They're quick and easy to install. Honestly- I buy the K&N cold air intakes because the noticeable improvement of the engine note. Furthermore, the throttle response is a little better from stock. However, be aware, around shift points, there is an annoying whistle that resembles that of a throttle body spacer. Hence, the 4 star rating. FYI: Cold Air Intakes give meniscal power and MPG gains. Any MPG gains I might have gotten are destroyed by my led foot- The engine just sounds too good with 77.

More power!

I definitely feel more power with this intake; however, I purchased it for the increase in MPG. So far, I haven't seen the improvement I was hoping for. I'm seeing about a .8 MPG improvement. Today I'm purchasing a tuner in hopes that will give me what I'm looking for. It does look good under the hood!

Easy to install, sounds great. I did notice some improved power between 30-60mph. Have not witnessed any improved fuel efficiency, but then again that is not why i bought it.

Money well spent

I installed this before taking a 2K mile road trip down south. This sounds great when the gas is pushed and the mileage and HP was definitely increased. Installation was a breeze.

Overall a good package, easy to install. Under normal driving conditions there is no difference in performance and it is no more noisy than stock. When the skinny petal is pressed it does get noisy, like a four barrel kicking in, I personally like it. Next step is to get the air out as efficient as going in to complete this package, then I would expect a slight increase in mileage and performance.

Need more air!

This air intake kit is good, the first few days when I had it on my F150 5.0, it was really loud, but after a week or so, it's not loud anymore, just making a little bit more sound than the stock, I'm not expecting this air intake system to gain the sound, but the air volume, hope it will last long.

Great add on.

This is an easy and effective way to add a little more punch. According to their dyno tests, it seems to add more punch to V8s with 4 valves per cylinder then ones with 2 valves per cylinder. Figures, let 'em breathe!
