Green Cotton Air Filters has just launched a direct replacement filter for the 2.2i, 2.5i and 3.0i versions of the Z4 sports car.
This filter promises to improve air flow and filtration, which not only means better performance but, according to Green, also greater levels of protection for these powerplants.

Each filter, which is manufactured from two layers of tightly-interwoven cotton fabric, reinforced with stainless steel, is also reusable once it’s been cleaned and re-oiled using the Green Service kit (sold separately). This means Green Cotton filters have a much longer service life than the OE part too.

This filter for the Z4 is priced £54.04. Many more fitments are available, so call the official UK stockist of Green filters, Auto InParts, on: 01525 382713 for further info.
