K&N 33-3025 Air Filter Product Reviews

Monday, September 10, 2018 - Part 33-3025
This is my second purchase from this fine Company. Purchased for our newish Mini Cooper S with the John Cooper Works package boosts the power to roughly 220bhp. We enjoy the benefits of the increased power in Sport mode, but ultimately expect to see the gain in fuel consumption over the coming months. I also have one fitted in my 2016 VW Passat Diesel R Line - 200bhp, and am currently returning 67mpg in Eco mode. I don't always drive in Eco mode though.

The air filter arrived in good time and was very good. However, it has not added anything to my car - that maybe as a Mini Countryman Cooper S's filter is a BMW one and is very good? Don't know. K&N filters have always improved my vehicles in the past.
