K&N Replacement Air Filter
  • Designed to Increase Power
  • Million Mile Limited Warranty
Kevin Hubert, Huntertown, Indiana
Gasket seal is really tight compared to original filter, (outside edge was a tad to big) had to finesse it into place. Once the lid was on and tightened down it looked like it was evenly sealed. Noticeable increase in performance and fuel economy is better, (2.5 with less than 13,000 miles). I am very happy with price and experience of shopping on the online store. Price was lower than throw away Chinese filter. Thank you! MADE IN USA!
