Customer Feedback

Great product! Fit perfect and works better than the stock air cleaner. I have a K&N air cleaner in my Ford diesel pick up and it works great.

Installed the cold air intake in my 2014 Ford Explorer Sport. Even with the turbo, the response is improved and the sound is awesome!

Excellent product. Received it in 1 day....FREE shipping. Easy install with easy to follow instructions. Sounds great and immidiate improvement in throttle response. I can't really feel the HP gain but definitely notice the torque gain. Highly recommend. IMPORTANT: You need a 3/4 inch drill bit if your sensor is the push in type. For some reason a Ford Fusion has 2 different types of sensors. I had my stock parts removed and had to get a buddy to run me out and get a drill bit. Other than that, 45 mins to install.
