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.
Craig Forbes, Colorado
Easy installation. Fuel increase was only .5 to 1 MPG with no real performance increase. 2001 Ford F250 4X4, stock 7.3L diesel. 6inch lift with 33 inch tires.
William Knight, Arizona
Have filters, now, for our old 1987 F250 Ford truck, our old 1987 Mecedes Benz 300TD Diesel wagon and our 1996 BMW Z3.
We're happy with all three filters (so far...).
