Fits perfect, easy install and as is the case with all my previous K&N filters, works great.

Having a 2015 Mustang Eco Boost, I was looking for either a cold air system or a K&N air filter but couldn't find any at the local parts store. I figured that they were not available yet however that was wrong, buying from K&N is the way to go. Free shipping and there isn't a middle man cost. I have used K&N air filters on my last three Mustangs. I've used the recharge kits, which is super easy. As far as performance gains, its a very mild kind of feel to how it runs with the stock paper filter.If [Name Brand] uses them with their performance kits through [Name Brand], you know that a lot of testing went into it.

I've used K&N filters in my past couple of mustangs. Excellent value, they last forever and can be washed and reused after re-oiling. Also, they probably add a few HP. My filter was shipped in less than a week, so I got good service.
