K&N Air filter - Page 3 - Toyota Yaris Forums

another thing to keep in mind is there is this stupid carbon filter on the top half of the airbox cover. it is plastic riveted in. if you remove this extra filter it's good for a few more CFM....if you plan to keep your stock box

For what it's worth, I took the K&N drop-in out after first reading about MAF gunk up in this thread. After reading a bit more and learning it comes down to the amount of oil on it after cleaning, I put it back in. Noticed a smoother idle. Can't speak for power and MPG seems the same, but definitely noticed a smoother idle.

K&N does not help much..i feel like it just saves money by washong, drying and putting them back on..
