Installed on our 2005 Mini Cooper and saw immediate improved throttle response and increased MPG by 2. Looks great and the deeper engine growl is awesome inside and out. Simple and quick 30 minute install. Would happily purchase again and highly recommend this product.

Oil filter came with all the replacement parts necessary to change the oil in my Mini Cooper. It included the rubber O ring as well as the drain plug gasket.
Ron, Corona, California
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.
