I love this product. I have always thought Airaid was the best and I bought a Ford F350 turbo diesel just because it had the Airaid system in it. Now I'm just waiting for the refund that I'm supposed to receive after I sent back a filter I bought that I ordered incorrectly. I will continue to buy Airaid as long as Airaid is in business. Thank you for your great customer service and the way you make a customer feel when talking to them. Thank very much for all the help that you have given me.
