Replacing the OEM filter immediately increased my fuel mileage in my Honda Fit 2.5 to 3.5 MPG everyday. I use this car as a delivery vehicle and keep track of the mileage every day. Impressive

I admit I was a little apprehensive, I even thought maybe it was the Placebo effect when I felt the car was going a bit better. But by the time I had driven a few weeks and then loaded up and driven up to and around the Lake district, I knew this product had single handedly made a noticeable difference and improvement to the way my car drives. Honda Jazz has all its torque and power high up - so you can get caught out at low revs, plus on motorways its often necessary to change down on hills - not any more. The power and pull went down lower after fitting this filter and there is a tad more at the top end as well - I am not saying its turned it into a sports car - more like I have a slightly bigger engine. Often on hills I am in a gear higher than before. Cherry on the cake was no damage to my fuel consumption - very similar and possibly a tad better.

Easy to fit and seems to do what you said it would.
