Customer Feedback

Went from a stock paper filter to a K&N air filter in my 2004 Mitsubishi Lancer ES. There is absolutely no hesitation with how my car responds now. I ran max A/C with fan speed in high, used fully synthetic oil, and the car still accelerated like a missile on the street. The engine is only a 2.0L 4 cylinder 120 HP non-turbo cast iron engine. Barely touched the gas and the car responded instantly even with a full load on the engine with four people. Mitsubishi recommends filter change every 30000 Miles, but with K&N you don't have to clean it till 80,000-100,000 miles on the filter. Much easier to get peak MPG at least, and yes a I drive a lot in the city and now top out at 24-33 MPG and 35-42 MPG on highway depending how I drive. The use of a stock or cold air K&N filter with fully synthetic oil will more than pay for them self.

I recently purchased my K/N filter for my 2006 Evo MR. I went from about 20 mpg to just under 23 mpg. I do have the engine flashed with some upgrades and this small purchase was probably the smartest one I have made so far. I will test the true mpg over the next few weeks, but I expect the numbers to be about the same.

Fit my 2014 Mitsubishi Outlander Sport perfectly. I drive conservatively so it added approximately 2-3 mpg to my usual average.
