I immediately noticed the increased performance. It was like driving a different car.

This is my third (2 motorcycles 1 car) K&N air filter and with that said, I am a believer in your product. I just installed the 33-2293 in my Mazda3 that I bought new back in 2008. While I only drive 9 miles a day I do drive it as Mazda intended Zoom-Zoom. From the moment I pulled out the drive way I noticed a big difference in throttle response and my old air filter wasn't even dirty enough to warrant the upgrade. Thank you for a fine product. PS: Just bought a new Mazda CX5.... What kind of air filter do you think I'll be putting in it???

Definitely put some zip in my MX-5! Easy to install. Fast shipping. This is my 4th vehicle with K&N filters or cold air intake!

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.

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.

Mazda 2.0l 111kw 2011, the best buy for the car.. Ready for new exhaust system..:)
Tim Sides, Coedpoeth, United Kingdom
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.
