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.

This induction is almost everything you'd want it to be. Its well made, using quality materials, its really easy to fit (only took me 30mins) & its pretty good value for money. It also gives my 3 series BMW a slightly louder and better quality exhaust note, whilst providing albeit small performance gains. The only thing I'm not so keen on, is the design specifically relating to my model of car. The heat shield as is currently configured doesn't utilize the incoming flow of air from the existing air scoops in the grill. It seems silly to me to not take advantage of a constant supply of cold air coming into the engine bay. It also now means that the fexi hose coming of scoops is distributing dust & debris from the road all over the inside of the engine bay. Now I know there is always a trade off in some aspect of fitting after market performance parts, and the benefits of having the filter (in my opinion) are worth it. It's still annoying to see that it could be better. 4/5 Stars.
