Great purchase, well worth the money.
The K&N air intake installed very easy, looked and fit great. It sounds better and looks better than the factory unit, not to mention the filter itself is cleanable and reusable. It's hard to notice the 10hp power increase on a truck as big as mine, but the throttle response is better and it seems rev up easier than before. I also gained a 1 full MPG on the highway. I bought it with a discount code and got a mail in rebate from K&N so I got a great deal as well!
