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........

The fit is just perfect and installation was so easy.

Car intake breathing is much better compared to stock air filter. Specially feel the smooth pick up between 30 to 60 mph. Very good and totally satisfied, just like every K&N product. Return customer: 88 Acura integra, 08 VW R32, 12 BMW 328i, 15 BMW 335i GT, 16 BMW z4 sdrive28i.
