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.
