Owner reviews for air filter

They replaced the filter and cleaned the system under warranty.

This made me go check if my car had one. It did even though it makes no sense on a convertible. So I changed it. 14 years and 70,000 miles and the filter was OE ford. The PO must not have known it was there or cared. It's like my A/c got a turbo mode now.

Hey that's one thing that is easy to replace in my e46 bmw 3 twist pins under the hood by the windshield and its out

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 went green filter and no lid at first. Added a ton of sound and enough turbo response to be noticeable. Recently added an RS lid bc I was worried about them being discontinued. It decreased the overall sound but made it better. It’s more high pitched like a tune 2JZ now.

I went with the K&N high flow filter, keeping the cover on. I’ve noticed a bit of a difference, but I’m too scared to take the cover off, as I don’t want particulates in my engine

I have run K&N's on all my cars as far back as I can remember. I'm waiting for spring when I can do a baseline comparision of HP before and after the K&N install with my GTECH Pro competition before I do the installation.

The K&N out of the box messed up the MAF on my old 2.5l Jetta, but 2.5l's are notorious for having a delicate MAF with an aftermarket intake.

K&N filters let in too much dirt when they get older & after a few washes following instructions you can see right through them. Then when oiled, dust plugs them up very fast. When over oiled, the oil can destroy the MAF. All in all not worth the $60 for a panel.
