Houston Hunter Jr, Marrero, Louisiana
I received the filter kit in reasonable time, all of the parts seem to be there. The installation was realitively straightforward. The only real issue that I had was, it took two people and clamps to close the cover enough to install the 10 nuts and washers. One person could NOT do this alone. I bought this unit because I was frustrated with the difficulty in changing the OEM filter without breaking something. Who knew this would not be much better. At least I won'the have to buy a new filter each time.

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.
Charles Loftus, Phoenix, Arizona
Wonderful system, it is a tight fit. I noticed a HP difference right away. My only issue are the screws. Two have loosened and fallen off. Others are getting stripped out. I'm waiting for a call back from K&N to see how I can get a replacement set of screws.
