Air filter K&N or Fram

I 3d printed and designed a cold air intake adapter that works like the Neuspeed intake. I put a big ol’ K&N filter on it and made the car much better on levels of acceleration and throttle response.

I removed the air filter (standard, paper one) and found it clean. I replaced it with a K&N anyway.

I had the smell problem. Dealer changed the filter, didn’t help. I installed FRAM CF12552 and that took care of it.

I use K & N filters on all my vehicles, both air and cabin, probably around $100.00 for both. They are a lifetime filter, they need to be cleaned occasionally, about every 30k or so, but you'll never need to buy a filter again! It made a difference in performance of my Pilot and every other vehicle I've owned.

So far, I haven’t had any trouble with the K&N air filter. The only thing I could see being an actual problem is if you don’t remember to clean it often enough.

I bought a K&N for my 23 GT. Works great.

I have the K&N one. There wasn't much noticeable difference for mine, although mines a Non-S. It did save me more money long term as I only have to clean it and prime it vs replace it.

I wind up usually coming back to K&N as I have ran them in about 5 different vehicles over the years including in Corvettes and 8cyl. trucks. I prefer them unoiled after cleaning that way you minimize fouling the maf sensor. As far as performance gains in my 1.4l base Jetta- throttle response is a bit improved but I don’t know if there is a gain in hp (6spd manual as well).

These k&n air filters are trash. They basically dont filter at all. Thats how they achieve increased air flow.

I am not a fan of K&N filters because they have to be cleaned and supposed to be air dried because blow drying can tear the media. I'll be damned if I'm going to notice my air filter is dirty and have to set aside a few hours of my day for it to dry in the sun before I can oil it and drive again, I rather just buy a $10 filter and be done.

Not to mention if you apply too much oil it can get into the MAF sensor and from what I've seen they also have less surface area than a paper filter, albeit they probably don't need the extra surface area, but it does mean they can clog faster.
