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.

I love this K&N Air Intake. Look's so much better than the stock Ford Intake that came on my 2006 F150 STX. The sound is Awesome I did not think i would be able to tell a difference in the sound but along with my FlowMaster Exhaust you can tell it's not stock, it sounds great, when you step on it you can hear the Air being sucked into the Intake. On MPG, I've been using it for about 2 week's now, I fueled up and almost run it all out before installing the new Intake, then fueled up again after it was installed and drove the same way back and forward to work. I can tell some change in MPG, it really does help. There is also a change in the  Throttle response and HorsePower. Installing this Intake is easy to do, and when you open the hood, It's the first thing that hit's your eye's. The only thing i had a problem with is the Intake tube had a spot on it about the size of a half dollar that looked like it had sand paper took to it, almost like the tube had been used before. But luckily it was on the bottom of the tube so when installed you never see it, so no big deal really. All in all i give this K&N Intake a 5 out of 5, I love it.
