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.

I got the K&N for my 2009 Mini Cooper S. Great price from K&N directly and it was shipped and delivered quickly. EASY installation and took all of 5 minutes. I'm a happy camper and good for 50K miles before needing cleaning.

Installation was very easy and only took about 20 minutes. One area needs improvement regarding fit. The metal replacement for the top of the air box should have thicker tabs to fit the back of the lower portion of the air box. Either thicker tabs or slip on spacers would help. My unit had a rattle at idle from the tabs vibrating in the lower air box so I built my own spacers which cured the rattle.
From a performance perspective I couldn't really determine a power increase through seat of the pants evaluation. Fuel mileage has stayed the same as it was. I'm using this unit on a Mini Cooper S Roadster and I consistently get 37 to 40 MPG and I don't baby the car. I also have a Quicksilver exhaust system installed.
The intake sound is very good and the blow off on the turbo is more noticeable than stock.

Overall, I'm satisfied with the purchase.
