I have been driving my 2013 Ford Transit Connect for a couple of months. I have purchased KN filters for all of my previous vehicles. The filter in my Vuck ( best description of a van and a truck) has increaincreased the power in my Vuck. ..and only slightly in the mileage category. I find it important to be able to pass someone on a 2 lane and this filter did it all. If you have a Vuck I strongly recommend it.

Easy step by step installation, amazing timing on the shipping. I have a ford 350 with a 6.0 and any one that has one knows the 7.3s are way better but after I put this on it was an amazing difference in truck all together, worth the money.

I was very impressed overall with ordering from K&N. My order shipped same day and arrived when it was supposed to. The cold air intake system I ordered for my 2003 Ford Crown Victoria Police Interceptor fit very good and the installation was simple. The instructions provided are excellent with step by step instructions with pictures of a Crown Vic engine bay. The increased performance can be felt along with increased throttle response. The sound of the air intake working under hard acceleration is a bonus You can really hear the air being drawn in and it sounds good
