K&N 33-2335 Air Filter Product Reviews

Friday, August 10, 2018 - Part 33-2335
Replaced MX5 manufacturers filter on my 2011 2.0L Sport with K&N couple of years back and noticed real differnce in pick-up and top revs. Suddenly found red-line limiter whilst getting onto the straight at Brand Hatch. Never happened before so was quite a shock. Thought I’d broken it - nah Bellettproof. Expect better driving performance not turbo power and rid yourself of one of the many manufacturer’s deliberate performance restrictions designed for the US market. John. LONDON

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.
