Your customer service department provided great service when I had to reorder/exchage air filters. I do like how your air filter works.

Needed a shorter filter to fit my 383 in a 78 Corvette so I asked a K&N tech if they had something. He sent me an email with this part number (E-3740). Fits perfect and since it is a lifetime filter, you can't beat the price.
