Customer Feedback

I can't compliment the kit more than the performance does. The kit brought new life to a 20 year old engine. The ease of assembly made it even more enjoyable. Thanks for a great product. Mike '96 Ford Bronco

Ordered for my ford f150 because i like the way it's made, found I can now buy it in my local walmart store.

I didnt think it would make that much of a difference. My 02 Ford F150 4.6 has been having issues with power and it was dogging out on me. I went for a drive after i installed it and WOW It sounds so mean and the power is unbelievable. I wasnt expecting that much of an increase. Ill have to drive it more to see if the problems went away. I struggle up the same hill every day on the way home from work when i just took it out i accelerated faster up the hill than i did before on flat ground i fell in love with my truck all over again. Thank you K&N you guys are amazing I am forever grateful i am going to tell everyone i know about your product.
