Great product.

Got my filter fast and it works great. I have it on my 09 maszdaspeed3 and it helped throttle response and woke the car up a little,. and you can even hear the turbo a little better. That being said, my stock filter was at least two years old before getting the K&N drop in. Next step, going to the dealer and letting them clean the intake for optimal performance.

This is my second K&N filter I've purchased. The first was for my wife's car. It was easy to install, and I definitely noticed an increase in pickup. This time I ordered the wrong filter, which brought customer service to bear. Daniel was most understanding and accommodating, shipped me the correct one instantly upon receipt of the UPS tracking number for the return. I haven't driven the car since I installed it, but anticipate the same increased acceleration.

Had K&N filters on every car and bike for three decades. This filter was plug and play, just like all the rest! I would consider upgrading to a cold air system you make but not one that requires removing the entire front clip like some do. Your turn. Thanks for continuing to make a superior product and use this letter as a testimonial if you desire.

Filter for 2010 Miata and 2015 Civic. I haven't had but one drive with the Miata, and I think there is a difference, but with the Civic with a five speed, I'm getting 40 miles per gallon on the highway, and almost that on secondary country roads. I'm still breaking the car in gradually, so I haven't had a chance to really test the performance, but so far, VERY positive results!!

Okay, so first I have to thank the guy who said it fits the i-Stop Mazda 3, because I wasn't sure until I read that. Secondly, the air filter I took off was filthy, had grass in and everything, so basing my experience after that. Can I tell the difference? I think I can, but that might be wishful thinking, the car does feel more responsive, and whereas it had a tendency to stall starting off in cold damp weather, now it seems to be flawless. But I have only done about 100 miles since buying the filter. Am I happy with my purchase? Yes. Would I buy from again? No doubt.

I have been using K&N filters exclusively for 35 years and would use no other - I still have the my first K&Ns, which are destined for reuse. All our vehicles get a K&N at their first service. The current purchase was for a Mazda 3 I-Stop that appears to be a limited run design. Annoyingly, it is more expensive than the standard larger K&N for this vehicle. Purchase from K&N UK direct was as cheap as anywhere else with a delivery that was swift and trouble free. The replacement and fit were perfect as usual.
