K&NEngine Air Filter: Reusable, Clean Every 75,000 Miles, Washable, Premium, Replacement Car Air Filter: Compatible with 2002-2012 MAZDA/FAW (6, Atenza, FAW Ruiyi, MPV, Pentium B50, B70), 33-2278

From my experience compared by other brands the K&N Filters is the Best .

I installed this filter into my car but I can't tell any performance different from a conventional filter so far. Perhaps time can tell? This supposed a washable filter. But it must use special solvent from the manufacture. There no cleaning instruction in the box, it only cautions not to use compress air or wrong type of cleaner. Load knows how much cost of the cleaning solvent? I am not too happy about that. But the filter looks very good.Kim

perfect fit like original , very nice sound

So far so good. Don't know why I waited this long to put one of these in my vehicle. I will add one of these to my other vehicle when the time comes to change it.

This is my first K&N product and I bought it primarily because of some positive things I've heard from friends about K&N. The filter was a snap to install on a 2004 Mazda MPV, just two clips and drop it in. I didn't realize that it was washable so that was a bonus that when it's dirty I can just wash it off and put it back in. Not sure that I noticed any significant difference from having this filter.

I love K&N Filters. Period

This filter is well worth the money. I have had it for 30,000 miles now and it hasn't missed a beat. Very small improvement in performance you can barely tell but when going up hills you can tell it is getting more air. My favorite thing is that it lasts forever and cleans in a snap.

The item fit fine with no modifications.I have nothing else to compare it to.Unknown at this time if there was any mpg increase - it's only been a week.Did not notice any performance difference, but the car is not driven hard.I figure it was the same cost as 3 factory filters so if it lasts until 90,000 miles, it will pay for itself.

Mazda 6 MPS - a little tight to fit, but it's in there and the lid's on !!

Gave instant performance upgrade, recommended

Turned up sooner than expected, which was a bonus. Fitted it and noticed the improvements in performance straight away. Recently did a long run to Cornwall and the MPG was great, even with towing a caravan. Have used K&N filters on previous car's and they have always given great results. Would recommend without question.

Received filter earlier than expected which was an added bonus and have shared the experience and cost with fellow members of the Mazda 6 Owners Club

cheapest k&n i could find and has made a slight difference, which is always good =)
