Fantastic. I'm excited about having my dealer install it.

A+ quality. Awesome sound, so now I can hear more induction noise and better performances. Very happy

I'd just like to echo the other comments about how easy it was to find the right product, order it and how quickly it arrived from the US to Aus. I ordered a panel filter for the stock air box on a 2016 BMW Z4 M-Sport - found the part in seconds using your search by vehicle function. Paid for it with just a few taps and it was installed in my car three days later........
