The part is apparently good quality. It was a simple installation, but the directions on how to mount the bracket were fairly unclear. However the part works well and creates good torque in the upper half of engine revs where the stock intake was lacking. It also creates a better deeper sound in those rev ranges as well. Overall I am impressed and satisfied.

Incredible! I am an 18 year old on a very tight budget and had to work 2 weeks to get the money for it, and I was worried I would be disappointed in it. I mainly bought it for sound improvements and I got just that. With every push of the gas pedal I get a very distinct PSSHH sound as it gulps in air, and then it basically increased the volume of my engine. It did nothing to my exhaust sound, but the engine itself sounded far far better. Furthermore, I do not see a huge change in horsepower or MPG as 9HP is nothing drastic, but I am sure it still helps. I have a 2001 BMW 325i and this filter kit came with everything needed and I installed it within 90 minutes, and used tools I found around the house. This is the first and only modification I have ever done to any vehicle and the instructions were clear and easy. I am beyond happy with this purchase, and have recommended it to many friends.

Absolutely perfect. Easy DIY install for someone without previous mechanical experience, and I can feel the extra umph whenever accelerating. I would recommend to anyone looking for a quick and easy performance upgrade.
