I would have given a better review of this product but the 90 degree tube that bolts to the intake/throttle body is cheap plastic. Tried to tighten it down and the threaded nut cert broke free and the bolts wouldn't tighten.

The K & N intake system is first rate, this is the 3rd one I have installed, and also the most difficult. There were several steps that were not applicable to my truck. The pictures in the instructions were way too small for these aged eyes, and I think the instructions are important as the 3 I have installed were all different, due ti different production years. Great product, great sound, better mileage, and more horses. What's not to like.

Was looking for an intake to give a complete upgrade to the engine. K&N was perfect. Upped my MPGs and can definitely tell a difference in acceleration. Also, the engine sounds a lot better.

Looks good and fit good! All you can ask for. Haven't noticed any difference on the mpg yet but we will see!! Make sure you go step by step.

I've only had it on my 08 F150 for a couple weeks but there has been a noticeable increase in power. As far as mileage I'm not sure yet. It was easy to install, it takes a little longer then expected to install

Easy to install only took about an hour on my f150. Haven't noticed any increase in the gas mileage but does seem to have a little more go.

Looks good, sounds great! Better throttle response. Not sure on increase of mpg, due to not being able to keep my foot out of it.

This went on my grandson's truck. He is 17 and his first project for his (formerly his Dad's truck) truck. I just assisted when necessary. Really, I only had to intervene a couple of times with an extra hand in hard to reach spots. It was that easy!
