Adds a couple HP but it definitely helps with the mpg. You can hear a whistle when you step on the gas. Really RECOMMEND this K&N Cold Air Intake.

Installs in about an hour with just a few tools. I think that they should come with the rubber already installed or at least have the pieces the right length so you dont have to use tin snips to cut them. not really sure it is necessary anyway. screws on clamps loosen up eassily, maybe they should come with loctite on threads or at least mention to customers to apply some. these are just my thought for easier install for people that are not as mechanical. I love the performance though.

The nice thing about having a car you really like, one that has you standing silently in the garage just to watch the light reflect off the bodywork, is that you can then personalize it. The K&N 57 CAI is my latest addition. Top quality, flawless instructions, great performance results. My mileage has gone up, and so has the performance. Great combination! No downside.

The product seems to really increase my acceleration and the sound is unquestionably more bassie. It looks great under the hood.

This was my first time adding anything to my mustang. I have to say the quality of the parts were great, and the price was a great deal as well. As far as the installation went; everything was fairly straightforward, except for when I needed to cut 6" off of the factory vent tube. The pictures were not very specific on what I was supposed to cut. Also, K&N made specific mention to not get rid of any of the factory pieces, and yet they had me cut the factory piece in order to make the K&N part work. If something went wrong and I had to put the factory parts back on. I would have had to order a new vent tube to replace the one that I had to cut. Luckily, I ended up cutting it correctly and everything works just fine. Not sure how K&N could have made the factory vent tube fit without cutting it, but it would have been helpful if I could have had a video to watch for my specific vehicle. The only video tutorial that they had on their site was for the older model V6 mustangs, and that wouldn't have helped in this situation. Other than that one issue; everything went smoothly. This weekend I'm going to check all the bolts and make sure none of them have loosened over the past week. As far as performance goes. I can tell a slight improvement in responsiveness. I typically don't hit higher RPM's, but even at the lower end it seems to help a little. I'm sure that having an automatic V6 mustang limits my performance as well. Overall, great product. I'll be looking for more ways to improve my performance.
