There was problem with the sizing of the original filter I purchased. Once the customer service agent determined the problem was on their end, a replacement was sent immediately at no charge. The filter I received fits perfectly. Great! Thank you.

I have been buying K&N Air Filters for a number of years, and that is because I want nothing but the best. Good product and good price. If you want the best filters, buy the best....K&N.

I had to return the previous model because it was the wrong fit so it has been a process, however I appreciate Etoria. She assisted me and made the process so much easier to order the correct filter. Michael Weston

This was an easy to install, direct replacement filter for my 2004 JCW MINI Cooper S (R53) factory boxed filter setup. The cotton filter comes pre-oiled out of the box and ready to install. It also comes with a convenient hose clamp for the filter's flange. If you are wondering if this product needs filter oil, it does. Its not clearly mentioned in the spec list. The cotton gauze material of this filter needs to be oiled to maintain tackiness during operation. I would recommend buying a filter maintenance kit (filter oil and cleaning spray), especially if you live in dusty areas. My driving style varies from spirited driving to freeway cruising speeds and I have noticed a small increase in MPG for cruising speeds from about 28 to 32 mpg. Increased MPG during spirited driving was negligible. Overall, this is a great replacement for the expensive factory filter based on cost, quality and maintainability.
