K&N RC-5178 Oval Universal Air Filter Product Reviews

Wednesday, November 7, 2018 - Part RC-5178
K&N air filter for 06 Ford super duty truck with 6.0 power stroke diesel was easy to install, replacing a 12 year old filter with 240,000 mileage.

I was planning a road trip and ordered a replacement for my 10 yr.old filter. Upon install I was missing a silicon sleeve and clamps. The were sent red label ups without question. I was able to leave a day early. Thank-you Mark

Talked to Victor today because the new style filter does not fit my 2005 F250. He was aware of the problem and is shipping me the parts I need. Flat out the best customer service I have ever had. Thanks Victor and K&N.
