Infiniti Parts for Sale

This page lists the Infiniti parts we sell for the G35, G37, Q50, Q60, QX50, QX56, QX60, QX80, JX35 and FX. You can buy every part shown above online, and each product page gives the models, years, engine and OE or interchange number it was made for.

Infiniti is Nissan's premium brand, so most Infiniti models share engines, transmissions and chassis parts with Nissan cars. The G35 is closely related to the Nissan 350Z, the QX60 and JX35 to the Nissan Pathfinder and Murano, and the QX56 and QX80 to the Nissan Armada and Patrol. That is why several of the Infiniti parts here also list Nissan models, and why our Nissan parts page is worth checking too.

Below you will find the parts grouped by system with their specs, common Infiniti repairs, how to check fitment, fitting tips and answers to common questions.

Common Infiniti Repairs

Oxygen sensors on the QX56, QX80 and QX60

These V8 and V6 SUVs have four oxygen sensors: one upstream and one downstream on each side of the engine. When a sensor wears out, the check engine light comes on, often with codes in the P0130 to P0161 range, and fuel use can rise. Many owners replace all four at once on a high-mileage engine, because the others are usually not far behind. Our sets of four make that simple. See our car sensors collection for more.

Brakes on the QX60 and JX35

These are heavy three-row family SUVs, and pads wear faster than on a sedan. Squealing, a grinding noise or a pad wear warning are the usual signs. Ceramic pads produce less dust and noise than semi-metallic pads, which suits a luxury SUV. See all brake parts.

Exhaust upgrades on the G35

The G35 shares the VQ35DE V6 and much of its exhaust layout with the Nissan 350Z, which made it a popular car to modify. A cat-back system changes the sound and can free up some flow. A downpipe and cutout go further. Check your local noise and emissions rules before fitting, because they differ a lot between countries. See exhaust parts for more.

Wheel bearings

A humming that rises with speed usually means a wheel bearing is going. The hub assembly we list for the QX50 and QX60 is a bolt-on unit with the bearing built in. See wheel bearings and hubs.

For background on the brand, the Infiniti article on Wikipedia lists the model history and how the names changed in 2014, when the G became the Q50 and the QX56 became the QX80.

How to Make Sure Infiniti Parts Fit

  1. Model name and year. Infiniti renamed its models in 2014. A G37 sedan and a Q40 or early Q50 may share parts, and a QX56 and QX80 may share parts, but check the years listed.
  2. Engine. Many Infiniti models came with a choice of V6, V8 or hybrid engines. O2 sensors, plugs and exhaust parts depend on the engine.
  3. Drive type. Rear-wheel and all-wheel drive versions often use different drivetrain and suspension parts.
  4. Body style. The G35 came as a coupe and a sedan, and exhaust systems differ between them.
  5. OE and interchange numbers. Match numbers like 313901XJ0A, 513296, P1649 and 234-5095 with your old part.

You can always send your VIN through our contact page and we will check for you.

Fitting Tips

  • O2 sensors: use an O2 sensor socket, and work on a warm (not hot) engine so the old sensors come out more easily. Do not get anti-seize on the sensor tip.
  • Exhaust: use new gaskets and leave all bolts loose until the whole system is hung, then tighten from the front back so nothing rattles against the body.
  • Brake pads: clean and lubricate the slide pins and bed in new pads before hard braking.
  • Transmission pan: use the correct transmission fluid for your car and refill to the level in the service manual.
  • Fog lights: coloured lights may not be legal on public roads in many countries. Use white or amber as required where you drive and keep coloured modes for shows and private use.

Infiniti Parts FAQ

Do Nissan parts fit Infiniti cars?

Many do, because Infiniti models share engines and platforms with Nissan models. Always check the fitment list for your exact model and year.

How many O2 sensors does my QX80 have?

The V8 has four: two before the catalytic converters and two after. Our set includes all four.

Will a cat-back exhaust trigger a check engine light?

A cat-back system goes after the catalytic converters and normally does not affect the sensors. Downpipes and cutouts can, depending on design.

Is the G35 the same as the 350Z?

They share the platform and the VQ35 V6, so many engine and exhaust parts are shared. Body, interior and some suspension parts are different.

Are RGB fog lights legal?

It depends on the country. Many places only allow white or yellow front fog lights on the road. Check your local rules.

Do you deliver Infiniti parts to my country?

Countries and delivery costs are shown at checkout. See our shipping page.

Infiniti and Nissan: What Is Shared

Infiniti is Nissan's luxury brand, and most Infiniti models are built on Nissan platforms with Nissan engines. The Infiniti G35 shares much with the Nissan 350Z, the QX60 and JX35 share with the Pathfinder and Murano, the QX56 and QX80 share with the Armada and Patrol, and the Q50 and Q60 share engines and many drivetrain parts with Nissan models. That means many engine, brake, sensor and suspension parts are the same across both brands. In this collection, the 3.5L V6 O2 sensor set fits the QX60 along with the Maxima, Murano and Pathfinder, and the front and rear ceramic brake pads fit the JX35 and QX60 alongside the Murano and Pathfinder. Interior trim, lights and some body panels are where Infiniti differs. Browse Nissan parts too when shopping.

VQ and VK Engines

Most Infiniti models from the 2000s and 2010s use the VQ family of V6 engines, in 3.5L and 3.7L sizes, found in the G35, G37, FX35, M35, Q50, Q60 and QX60. The VQ engines are known for strong power and a distinctive sound. The QX56 and QX80 use the VK56 5.6L V8. Later models use the VR30 3.0L twin-turbo V6. Common maintenance items for the VQ engines include spark plugs, ignition coils, O2 sensors, engine mounts and valve cover gaskets. Our LFR5AIX-11 platinum spark plug set uses an interchange common to many Nissan and Infiniti V6 engines; check the number against your old plugs. The V8 QX models use the QX56 and QX80 O2 sensor set.

G35 and 350Z Exhaust Upgrades

The G35 coupe and sedan from 2003 to 2007 share many exhaust parts with the 350Z. Owners often upgrade the exhaust for a better sound. Our 350Z and G35 cat-back exhaust replaces everything behind the catalytic converters, and the exhaust downpipe for the 350Z and G35 fits between the manifolds and the rest of the system. Check which body style and year your G35 is, because the coupe and sedan exhaust layouts can differ, and check local rules on exhaust noise and emissions before fitting performance exhaust parts. An electric exhaust cutout lets you open the exhaust for shows and close it for normal driving.

Transmission Service on Infiniti Models

Many rear-wheel-drive and all-wheel-drive Infiniti models use a 7-speed automatic transmission. Its oil pan can be damaged by road debris or develop leaks at the gasket. Our transmission oil pan 313901XJ0A fits the Q50, Q60, FX, G37 and related Nissan models. When you replace the pan, fit a new gasket, refill with the exact fluid type the manufacturer specifies, and check the level using the correct procedure at the right temperature. Using the wrong fluid can cause harsh shifts or damage.

Wheel Bearings on Crossovers

Infiniti crossovers like the QX50 and QX60 are heavy and often have all-wheel drive, which puts load on the wheel bearings. A humming noise that rises with speed is the usual sign of a worn bearing. Our front wheel bearing and hub assembly 513296 fits the 2019 QX50 and related models. See wheel bearings and hubs for tips on diagnosing bearing noise.

Lighting Upgrades for the Q50

The Q50 is one of the most popular Infiniti models for styling upgrades. Our Q50 Sport RGB LED fog lights replace the factory fog lamps and connect to a phone app over Bluetooth. Check that your car is a Sport model with the matching bumper, and check your local rules, since coloured front lights are restricted on public roads in many places. Find more lights in lighting.

Model Names Changed in 2014

Infiniti renamed its range from the 2014 model year. The G sedan became the Q50, the G coupe became the Q60, the M became the Q70, the EX became the QX50, the FX became the QX70, the JX became the QX60, and the QX56 became the QX80. Many parts carried over across the name change, so a part listed for the JX35 may also fit the early QX60, and parts for the FX may fit the QX70. Always confirm the year and engine, but keep the old and new names in mind when searching.

Using Your VIN

If you are unsure which part fits, the VIN tells a parts specialist the exact model, engine and build details. Send us your VIN and the number from your old part through our request a part page.

Infiniti Sedans and Coupes: G, Q50 and Q60

The G35 and later G37 made Infiniti's name in sports sedans and coupes in the 2000s. The G35 arrived for the 2003 model year in sedan and coupe form, followed by the G37 with a larger 3.7L V6. From the 2014 model year, the sedan became the Q50 and the coupe the Q60. These rear-wheel-drive cars, many with all-wheel drive, are popular with enthusiasts for their engines and handling. Common upgrades include exhaust systems, intakes, suspension and lighting. Common repairs include ignition coils, oxygen sensors, wheel bearings, front suspension bushings and brakes.

Infiniti SUVs: FX, QX56, QX60 and QX80

Infiniti's SUVs range from the sporty FX, later the QX70, to the large QX56 and QX80 built on the same platform as the Nissan Armada and Patrol. The QX60, formerly the JX35, is a three-row crossover closely related to the Nissan Pathfinder. On the large V8 SUVs, the oxygen sensors, the brakes and the rear suspension work hard. On the QX60, owners should watch the CVT transmission fluid service and the brakes, which wear quickly on this heavy vehicle.

CVT Transmissions

Several Infiniti and Nissan models, including the QX60, use continuously variable transmissions (CVTs). A CVT uses a steel belt between two variable pulleys instead of fixed gears. It is smooth and efficient, but it is sensitive to fluid condition and type. Use only the CVT fluid specified by the manufacturer, change it at the recommended interval, and avoid hard towing beyond the vehicle's rating. Symptoms of CVT trouble include a whining noise, a juddering feel when pulling away and a loss of power under acceleration.

Brakes on Heavy Infiniti Crossovers

Crossovers like the JX35 and QX60 weigh over two tonnes when loaded with passengers. Their pads and rotors wear faster than on a sedan. Our front and rear ceramic brake pads fit the JX35 and QX60. Ceramic pads produce less dust and noise than semi-metallic pads, which keeps alloy wheels cleaner. When replacing pads, check the rotors for thickness and smoothness, and resurface or replace them if they are worn or warped.

Oxygen Sensors: Upstream and Downstream

V6 and V8 Infiniti engines have oxygen or air-fuel sensors before and after each catalytic converter. A V6 typically has four sensors, two per bank. When one fails, the engine may set a code for that bank and sensor position, such as bank 1 sensor 1. Replacing sensors as a set, like our O2 sensor sets for the 3.5L V6 and 5.6L V8, makes sense on high-mileage engines, because the other sensors are the same age. Use anti-seize on the threads unless the sensor already has it, and do not get anti-seize on the sensor tip.

More Questions About Infiniti Parts

Do Nissan parts fit my Infiniti?

Many mechanical parts do, because Infiniti models share platforms and engines with Nissan. Check the fitment for your model and engine.

What spark plugs does my VQ engine use?

Many VQ engines use long-life iridium or platinum plugs. Match the number on your old plugs, or check your owner's manual for the specified type and gap.

Are the RGB fog lights legal on the road?

Coloured front lights are restricted in many places. Use the colour modes for shows and off-road, and check your local rules.

Will the 350Z cat-back fit my G35 sedan?

Check the listed fitment. The coupe and sedan exhaust layouts can differ.

Infiniti Maintenance Highlights

  • Engine oil: VQ engines like clean oil; change it on time with the grade in your owner's manual and check the level between changes, since some higher-mileage VQ engines use a little oil.
  • Spark plugs: long-life plugs still need replacing at the scheduled interval; on V6 engines the rear plugs sit under the intake plenum on many models, so plan the job accordingly.
  • Coolant: use the correct long-life coolant and replace it as scheduled.
  • Transmission fluid: automatic and CVT fluids need changing at the intervals in the manual, especially if you tow or drive in heavy traffic.
  • Brakes: inspect pads and rotors at every tyre rotation on heavier models like the QX60 and QX80.
  • Differential and transfer case: on all-wheel-drive models, change the fluids as scheduled.

Common Noises and What They Mean

A hum that rises with speed: often a wheel bearing or tyre noise. A clunk over bumps: worn sway bar links, control arm bushings or strut mounts. A squeal on start-up: a worn serpentine belt or tensioner. A ticking from the engine: can be an exhaust leak at the manifold or valvetrain noise. A grinding when braking: pads worn to the metal. Diagnosing the noise before buying parts saves money; a short drive with a trusted mechanic can narrow it down quickly.

Infiniti Exhaust Notes

The G35 and 350Z share a well-known exhaust sound, and many owners fit performance exhausts. Keep in mind that a louder exhaust can drone at highway speeds, and noise limits apply in many places. Choose a system with resonators if you want a sporty sound without cabin drone.

Exhaust Downpipes and Emissions

Exhaust downpipes connect the exhaust manifolds to the rest of the exhaust system. On the 350Z and G35, aftermarket downpipes are popular for sound and flow, and some designs remove or replace the factory catalytic converters. Removing catalytic converters is illegal for road use in many countries and states, and can cause a check engine light and failed inspections. Before buying, check whether the downpipe keeps the catalytic converters and whether it is approved for road use where you live. Our 350Z and G35 downpipe listing describes exactly what it replaces.

Front-Wheel-Drive vs Rear-Wheel-Drive Infiniti Models

Most Infiniti models are rear-wheel drive or all-wheel drive based on a rear-drive layout, but the QX60 and JX35 are front-drive based, and the QX50 has used both layouts in different generations. That affects which axles, wheel bearings and suspension parts fit. Check the drive type on your vehicle before ordering.

Infiniti Parts Ordering Checklist
