There are many loyal K&N customers willing to purchase a performance intake system the first day that they purchase a new vehicle. This might be due the proven horsepower gains made time and time again on the K&N dyno. Design is critical when it comes to making a product the guarantees horsepower. The key is to get the straightest air flow path possible as the air makes its way into the engine. All dyno test literature comes inside the box of each K&N intake and can be found on the K&N website on the product summary page.

Most factory intake systems choke down air flow and reduce engine performance. Air flow is important for big engines like the 6.0 liter powerhouse offered in 2007-2008 Chevy Silverado HD trucks. Automobile manufacturers sacrifice the power in order to quite engine noise but, most truck owners want to hear the engine roar when they mash the gas pedal. A truck is meant to perform, not spit out low emissions and sit silently at a stop light.

If you are looking for more performance out of your Silverado HD give K&N some thought. Part number 57-3067 is specifically designed to increase horsepower and torque. This K&N intake system made an estimated additional 11 horsepower and 13 lb-ft. of torque to the wheels. One simple bolt-on is all it takes to improve performance.
