The 57 Series Generation II air intake, also referred to as an FIPK, is K&N's ultimate performance product. These performance intakes are designed to increase power by as much as 10%. 57 Series FIPK's are CARB exempt, street legal in all 50 US states, come with K&N's Million Mile Limited Warranty and are guaranteed to increase power. K&N air intake systems replace 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 translates into more power and torque for your vehicle. The air filters on these kits are washable and reusable. Most of our air intake systems are easy to install using tools commonly available (see installation instructions).This part fits the following models:CHEVROLET Silverado 2500 HD 6.6L V8 DSL (2005 - 2006)CHEVROLET Silverado 2500 HD Classic 6.6L V8 DSL (2007 - 2007)CHEVROLET Silverado 3500 6.6L V8 DSL (2005 - 2006)CHEVROLET Silverado 3500 Classic 6.6L V8 DSL (2007 - 2007)GMC Sierra 2500 HD 6.6L V8 DSL (2005 - 2006)GMC Sierra 2500 HD Classic 6.6L V8 DSL (2007 - 2007)GMC Sierra 3500 6.6L V8 DSL (2005 - 2006)GMC Sierra 3500 Classic 6.6L V8 DSL (2007 - 2007)This list is a sample of all the compatible cars for this part.
