One of the easiest, and cheapest ways to increase horsepower and efficiency is by replacing your OEM air intake.

K&N is one of the most decorated, and trusted names in the performance intake Industry. And they've earned it! Through extensive development and testing, they've created a line of performance air intakes that promise moderate HP gains right out of the box! For example, without a professional tune, the LS3 system yields 17+ HP.

But HP isn't enough these days. Cost and fuel efficiency is a must, and K&N delivers. Most intake systems yield a mild fuel efficiency increase, and every air filter is washable and reusable. In addition to all that, every K&N intake system comes with a free Million-mile warranty.
