The K&N 57-3031-1 FIPK air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they 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 57-3031-1 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the air cleaner mounting tray. 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. 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 the existing factory mounting points. The tools needed are a screwdriver and two wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

I am overall very impressed. There were very detailed instructions on the installation, everything fit just as it should, and now my truck is running and sounds better than ever.

Very happy with the cold air intake. Took a trip with it and showed a slight increase in gas mileage. I also put a dual exhaust with 3 pipes on after my trip. Looking forward to pulling my 6000 lb trailer.

Great service, on time delivery. This cold air intake was an easy install, it took about 30 minutes to remove the old stock system and install my new K&N one. I notice a better throttle response, especially when towing the 5th wheel that's about 9,000lb. loaded. My ride is a 2004 Silverado 2500HD 6.0 with 120,000 miles on it. Thanks K&N.

Great product! Engine noise sounds better then ever and can tell when you step on it, that there's a K&N cold air intake under the hood. I'm very happy with this purchase and easy install. Thanks K&N.
