K&N Replacement Air Filter
  • Designed to Increase Power

This air filter is amazing. I have some noticable power gains and my gas mileage has improved even more so than the listed 38 mpg highway. Installed in about 15 seconds and it was ready to go. On a recent trip to Las Vegas I was able to drive from my home in San Diego to Vegas and back with a quarter tank of gas still in the tank. I will let you do the math on that one, but it is one of the best purchases that I have made for this vehicle.
