The K&N 63-3085 Air Intake fits some Chevrolet Silverado 1500, and GMC Sierra 1500 models. See vehicle applications link for details.
The K&N 63-3085 AirCharger air intake system replaces the restrictive factory air filter and air intake housing on some Chevrolet Silverado 1500 and GMC Sierra 1500 models. K&N air intakes are designed to dramatically reduce air intake restriction as well as smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-3085 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the original air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent hose. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install, usually in 90 minutes or less using your vehicle’s existing factory mounting points. The tools needed are a screwdriver, ratchet set and several wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

K&N 63-3085 Air Intake Product Reviews

2nd review. The system combined with a flo-thru exhaust, sounds like an '85 instead of a 2015. Good job.

Kit was very easy to install. Quality product, sounds awsome, and extra horse power is great for pulling trailer.

I like the 63 series K&N air filter I ordered for my 15 Silverado. The truck sounds good and there is a noticeable difference in the throttle response. I have not noticed a fuel mileage increase. The kit came with everything I needed. The install took about 30 miinutes and overall I am happy with the purchase.

Would have liked to had the option of a polished stainless pipe. Everything else was good. I've noticed very little fuel savings, not sure if the relearning is completed yet. Only been about a week and a half. Thanks, Bill Danel.
