K&N Replacement Air Filter
  • Designed to Increase Power
  • Million Mile Limited Warranty
David Hoffman , Fort Worth, Texas
Filter is doing a good job with some noticable increase in power / acceration and on some small, but positive increase in gas mileage. However, the QC on the product was a little below standard with some large excess plastic / rubber on the filter top where it seals with the top of the air filter housing. Appears not to be a problem, but y'all should notice these things in production as a mold or something is our of line.
Víctor Pereira, Sevilla, Spain
Perfect! Acceleration is much more constant, less lag in power and fuel consumption has improved.
Chris Pluch, Toronto, Canada
I saw an immediate improvement to both the performance and fuel economy. Neither were startling but both were noticeable.
