3.94 Inch Cold Air Intake System with Heat Shield, For 2015 Cadillac Escalade, Chevy Suburban/Tahoe/Silverado, GMC Yukon/Sierra

Cold Air Intake for the Escalade, Suburban, Tahoe, Yukon, and Sierra

This is a 3.94-inch cold air intake system with a heat shield, built for the 2015 Cadillac Escalade, Chevrolet Silverado, Suburban, and Tahoe, and GMC Sierra, Yukon, and Yukon Denali. If your factory airbox is choking off airflow with a restrictive stock filter and a long, narrow intake tube, this system replaces it with a larger-diameter tube and a shielded, cone-style filter designed to pull cooler air from outside the engine bay.

Why These GM Trucks and SUVs Share an Intake

The Escalade, Silverado, Suburban, Tahoe, Sierra, and Yukon for the 2015 model year are all built on General Motors' full-size truck and SUV platform, sharing the same engine bay layout and factory intake routing even though they carry different badges across the Cadillac, Chevrolet, and GMC brands. That shared platform is why a single cold air intake, sized to the same 3.94-inch opening, fits across all of these nameplates instead of requiring a separate part for each one.

• 3.94-inch (100mm) mandrel-bent intake tube for reduced airflow restriction

Compatibility

Fits the 2015 Cadillac Escalade, Chevrolet Silverado, Suburban, and Tahoe, and GMC Sierra, Yukon, and Yukon Denali. Because engine bay layouts and available engine options can vary by trim within a single model year, it's worth confirming your specific engine size against the fitment above before ordering, particularly if your truck or SUV has any existing aftermarket intake or airbox modifications.

Signs Your Intake Is Restricting Airflow

A restrictive factory intake doesn't usually fail outright the way a worn mechanical part does — instead, owners tend to notice it as a factory airbox that traps heat around the filter, a stock filter that's difficult to service without disassembling multiple housing pieces, or simply the sense that throttle response feels duller than it should for the engine's size. Because the change is gradual and the factory system technically still works, most owners only notice the difference in throttle response and intake sound once they've driven the truck with an open, shielded intake in place.

Why Owners Upgrade Their Intake

The main draw of a larger-diameter, shielded cold air intake is pulling in cooler, denser air from outside the immediate engine bay rather than air that's already been warmed by the engine and exhaust components nearby, since cooler intake air is denser and supports more efficient combustion than air that's already picked up underhood heat. Owners who tow, haul, or simply want a more direct throttle feel and a more noticeable intake sound under acceleration are the most common buyers of this kind of upgrade, and the washable, reusable filter also means lower long-term maintenance cost compared to replacing a paper filter element on a set schedule.

Installation Notes

Installing this intake means removing the factory airbox and intake tubing, mounting the new heat shield and filter assembly in its place using the factory mounting points, and reconnecting the factory sensors and hoses to the new tube. This is a bolt-on job that doesn't require cutting or permanent modification to the vehicle, and most owners can complete it with basic hand tools in well under an hour. Double-checking that all factory electrical connectors, including the mass airflow sensor, are fully seated before starting the engine is worth the extra minute it takes.
