K&N 33-2335 Air Filter Product Reviews

Monday, April 30, 2018 - Part 33-2335
Perfect, drop in, fit to replace the factory filter. I felt a noticeable difference in my Miata afterwards. I was definitely needing a new filter and I always go with K&N. Always good quality, from my Civic, my Camaro and now my Miata.

Easy to fit. Took less than 5 mins. I’ll be honest though. I’ve noticed no difference in performance at all much as I was will the product to improve efficiently and response. Overall I wouldn’t spend the money again given the choice.

A work colleague recommended a K&N filter to me, so I bought one directly from their website despite other online sites such as EBay offering their product at slightly higher prices. Unfortunately, I made a mistake with my car manufacture date and when the filter arrivied it was clear it wouldn’t fit. I immediately contacted them and they assured me that I would get a refund and that I should re-order my new filter, and gave me the correct part number. I did so, and straight away, my refund appeared on PayPal. Delivery of my filter was literally three days, which is exceptional as it’s free over a certain price. To me, what I fully commend K&N for is that when I contacted them for clearly my mistake was they advised me what to do and I had the correct item dispatched in return. I would fully recommend this company, not only because they sell top quality filters, but they also deliver a personal service to anyone who needs it.
