Customer Feedback

I used the same K&N drop-in filter on my 1990 Eagle Talon TSi AWD from 2002 to 2007, when I sold it.  The new owner of the car is still using the filter I purchased years ago.  I'm now using K&N air filters on my 1993 Mazda Miata, and my 1991 Mitsubishi Galant VR4.  It has made a night-and-day difference on the Miata, especially in low-end torque.  On the Galant, I now hit boost 200-300 RPM sooner, and I can definitely feel the difference in power.  Not only are K&N air filters proven to perform, they are also built to last.

Plus, K&N oil filters always have a nut welded on to the end of each filter.  As someone who changes my own oil, that's a godsend.

Toyota 75 Series Ute.

I owned a 1995 Toyota 75 series 4.2 litre Ute.  I could not drive from Cloncurry to Longreach on one tank of fuel.  I was lucky to get 495 kilometers to 84 litres of fuel at 2,600 revs. which is about 112 kmh Plus the vechicle was sluggish and had to be driven hard to get up and going.  It was recommended by a friend I fit a K&N filter.  I noticed the difference immediately driving in town.  The vechicle would pull in 5th gear at 40kmh and keep gaining speed without having to put the pedal to the metal.  I left Southport on the Gold Coast and drove to the main highway rounabout at Rockhampton before switching to the front tank.  Odometer read 712 klm's on one tank the vechicle was fitted with two fuel tanks.  I could get 84 litres out of the rear tank and 87 litres out of the front tank.  I drove 1466 kilometers at 2,600rpm on both tanks of fuel.  I could achieve 600+ around town because the vechicle didn't require hard driving to get to speed.  The vechicle went from returning around 5.5 klm's to a litre to around 8.57 klm's a litre.  I would recommend the fitting of a K&N air filter to any vechicle.  I have one fitted to my wife's Mitsubishi Galant GSR. and have now fitted one to my Landrover Discovery Tdi

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