This is a set of six \u003cstrong\u003eLFR5AIX-11 spark plugs\u003c\/strong\u003e, the platinum-tip plug that cross-references to the 4469, ILFR5B11 and PLFR5A11 numbers used across a lot of Nissan, Infiniti and Hyundai gasoline engines. One box covers a full V6, so you can swap the whole set in one go.\u003c\/p\u003e\n\n\u003cp\u003eWe sell a lot of ignition auto parts, and plugs are one of the easiest wins on an older engine. A fresh set brings back a stable spark, smooths out the idle and takes load off the ignition coils, which tend to fail early when they're forced to fire across worn-out gaps.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Choose These LFR5AIX-11 Spark Plugs\u003c\/h2\u003e\n\n\u003cp\u003eThe platinum tip on the center electrode wears much more slowly than a plain nickel plug, so the gap stays close to spec for a long time. That means a steady spark, smoother running and fewer trips under the hood. These are a direct replacement for the original interchange numbers, with the same thread, reach and heat range, so there's nothing to modify.\u003c\/p\u003e\n\n\u003cp\u003eNot sure your plugs are the problem?

Pull one of your old plugs and compare the number printed on the insulator, or check your owner's manual. Keep your cylinder count in mind as well: this pack has six plugs, which suits V6 engines. A V8 needs eight, and a four-cylinder needs four.
