K&N 99-04 Chevy Silverado V8-4.8L/5.3L Performance Intake Kit

The K&N 57 Series FIPK 57-3021-1 air intake system replaces your vehicle's restrictive factory air filter and air intake housing. K&N air 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 57-3021-1 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. The placement allows air to be directed past the mass air sensor through an aerodynamically engineered intake tube into the engine's throttle body for a guaranteed power gain. The oversized 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 and mass air sensor requiring only a screwdriver, ratchet set and several 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.Installation InstructionsUser 1Installation InstructionsInstallation InstructionsThis Part Fits: Year Make Model Submodel 1999-2004 Chevrolet Silverado 1500 Base 2004 Chevrolet Silverado 1500 Hybrid 1999-2004 Chevrolet Silverado 1500 LS 1999-2004 Chevrolet Silverado 1500 LT 2002-2004 Chevrolet Silverado 1500 WT 2004 Chevrolet Silverado 1500 Z71 2002-2004 GMC Sierra 1500 Base 2002 GMC Sierra 1500 HT 1999-2003 GMC Sierra 1500 SL 1999-2004 GMC Sierra 1500 SLE 1999-2004 GMC Sierra 1500 SLT 2002-2004 GMC Sierra 1500 WT
