Review on 🔧 K&N Engine Air Filter: High Performance, Premium, Washable Replacement for 2019-2020 MAZDA 3/CX-30: Compatible with Models 33-5096 by Andres Mayes

Looks good but doesn't fit as accurately as the Mazda filter it replaced. The sealing lips do not perfectly match the sealing surfaces of the air filter housing. It fits well enough and will presumably seal well, but that's a little disappointing. As for the claims of more power and better fuel efficiency - well, maybe especially compared to a filter that's gotten dirty and restrictive. It's likely to let more air through compared to a clean new paper filter, so there might be a few more ponies to be found; but only at full throttle and high revs. I don't feel any difference, but I didn't expect that either. I like it mostly because it doesn't need to be changed, just cleaned from time to time.
