Craig Forbes, Colorado
I bought the cold air box for my 2006 Ford F350, one year ago. The filter was just taken out for the yearly cleaning. Very nice system. I have seen an increase in mileage on the highway when towing my 5th wheel. Thank you for a great product.

Over all a nice unit, I suggest maybe making the air box about a 1/4 of an inch narrower its a real tight fit going in and maybe shortening the tube coming off the cover and adding another rubber hose so the cover sets on easier

Big improvement on accelerating. Don't know on mileage yet.only one of fuel so far. Very easy to install. Most of my driving is off road.
