K&N Cold Air Intake Kit: High Performance, Increase Horsepower: Compatible with 2001-2007 Chevy/GMC Heavy Duty (Silverado 2500, Silverado 3500, Sierra 2500, Sierra 3500) 6.0L V8, 57-3031-1

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 only 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.This part fits the following models:CHEVROLET Silverado 2500 HD 6.0L V8 F/I (2001 - 2006)CHEVROLET Silverado 2500 HD Classic 6.0L V8 F/I (2007 - 2007)CHEVROLET Silverado 3500 6.0L V8 F/I (2001 - 2006)CHEVROLET Silverado 3500 Classic 6.0L V8 F/I (2007 - 2007)GMC Sierra 2500 HD 6.0L V8 F/I (2001 - 2006)GMC Sierra 2500 HD Classic 6.0L V8 F/I (2007 - 2007)GMC Sierra 3500 6.0L V8 F/I (2001 - 2006)GMC Sierra 3500 Classic 6.0L V8 F/I (2007 - 2007)This list is a sample of all the compatible cars for this part.
