Review on 🔍 K&N Engine Air Filter: High Performance, Premium, Washable Replacement Filter for 2015-2019 BMW (120i, 125i, 220i, 230i, 320i, 330e, 340i, 420i, and More) | 33-3051 by Aaron Jensen

I swear by K&N filters but I wasn't planning on getting a used item. As you can see in the photo above, this is what the item looked like when I sent it to the mailbox. The box was intact but the ribbon had come over the edge where it had been torn earlier, presumably by another buyer. As you can see the plastic coating was removed and I'm not sure if it was cleaned, then I replied that the plastic had pink oil stains on it and no other ones I've bought had anything like it. I'm upset because I'm not sure if I should waste my time cleaning and throwing this out if it was in another car or not! Terrible product - should have read the latest reviews!
