K&N Replacement Air Filter

Amazing filter. Bought it back in 2011 from factory store with 31,000 miles on the car, dropped in the K&N and man did it make a huge difference. Gas mileage on highway went from 26 to 29, city improved slightly, only 2mpg up from rated which was 16, so still something. Acceleration and power came on sooner and throttle response was quicker. Extremely worth it. Now I'm just saving up to get one for my 2016 Focus ST.

Only had the filter in a few days, but it seems to add a little kick & engine seems to sound smooth as silk.

I didn't need to buy one, I already had one. I had to take my cold air intake off to pass smog and put OEM back on. Wasted money being on a retired income.

I have used this air cleaner on my Mustang since it was new (2008) and the performance has been excellent. Though the original is still in great shape, I purchased this as a spare for when I need to clean one and don't have time. I travel a lot and sometimes the areas are very dusty. Note: It is similar to the stock cold air system but a lot less expensive.

I received my filter promptly and in good order. I removed the original filter from Ford with little effort and was able to install the new one with some effort by bending it slightly into place without having to disassemble the connection joint. I appreciate that the screen is on the outside of the filter rather than having the paper composite on the outside and the screen on the inside like the original. That is the main reason I had to replace it because a critter had chewed the composite down to the screen and left exposed. Thank you so much for a great product that fits the Bullitt well.

The part was a great fit and was easy replacement for the stock part without any modifications.
