Horrible Customer Service By Summit Racing!! I have purchased three of the K&N Blackhawk Cold Air Intake system from Summit Racing. When I called Summit Racing about the tube having a manufactures defect, I was told that I didn't know what I was doing, He then put me on hold, to come back and tell me that the air flow sensor can be installed upside down. I explained that it can't be upside down and that the flange was welded upside down, and that I need a replacement. NOPE! That is what I was told. Call K&N and they will explain to you that that it can be upside down... I called K&N 3 days later (I'm busy), the K&N representative instantly knew what I was talking about, asked if I had the K&N box that was delivered, I said yes, he asked for me to read him some of the manufactures details from that box, and he said, we will send you a replacement tube, should arrive in 7-10 days... No worries about the shipping time, I appreciate the quality customer service and respectful manner in which this representative handled the situation. Summit Racing will sell you the same thing that you can purchase elsewhere, and will not help you past that point. They take your money, send you whatever, and then you are on your own from there... I will not buy from them again.
