Air filter K&N or Wix

K&N high flow lifetime filter. Higher airflow (you'll hear turbo spool and gain a few HP), and you never need to change it - you can wash it after 50-70,000 mi, or whenever you feel it's dirty enough to clean, but you've never got to buy another filter again...

Royal Purple HMX 5w 20 10-48 RP oil filter and a Wix air filter.

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.

Wix air filters cost me about $40 total and took five minutes to do both.

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

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.

I have the k&n filter and I don’t notice a difference, the only upside would be you can clean it and reuse it but other than that there’s not much of a difference than a paper filter

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.

K&N filters aren't really worth it as the increased air flow isn't going to result in any significant gains since air/fuel ratio is computer controlled anyway. Not to mention you would really need better exhaust and a tune to take full advantage of increased air flow. Also, if improperly oiled, they can cause MAF sensor issues.

SKIP the K&N filter. Not worth it at all. The oil that the K&N filters require can screw up sensors down stream.
