Air filter Mann or K&N

Works like a charm I love it and highly recommend!

I installed K&N. Great replacement for the stock filter. Noticed a bit more induction whistle and the car definitely feels like it breathes better.

I put in a K&N filter and the improvement is noticable. I posted my milage on a filter post. The 300 mile trip includes a mountain pass and other steep elevation changes. We normally get 21-23 mpg, but we got 25.6 going, 24.2 returning at 65 mph average speed each way. I made the trip again yesterday and got 26.1 mpg going, average speed 69 mph. My last tank of gas for normal driving around town for 350 miles with a mixture of city and highway driving had a 23.0 mpg average. That is 1.5 mpg better than normal. I attribute this to improved airflow.

I'm pleased with my K&N as well. It was given to me by my stepson, who works at an auto parts store. Otherwise, I would have maybe gone for the dry filter. I really like the mileage improvement this has given me as well as the noticeable better response.

K&N filters are reusable. Totally worth the upfront cost.

if you want a performance oriented filter James Baron Racing sells a dry flow panel filter that's a drop in replacement for most 2012+ Mazda's. They're made by K&N but have no oil whatsoever. They flow better than OEM and they're cleanable. Probably your safest option.

I found a used ABD racing filter and I could feel it with out a doubt. I bought a K&N filter and drilled holes in my box and I say it was a waste.

Not a whole lot of difference, that is until you swiss cheese the air box!

Over cleaning a K&N does more harm than good. K&N's need dirt to be effective. Clean K&N's let through too much dirt, until they become effective.

I'm not a believer in K&N. I've always thought of it as being rather gimmicky.
