"Oil-Free" ProDry S Filter

This intake kit replaces your restrictive factory air box. It features a 3-angle aluminum velocity stack adapter, 16-gauge powder-coated steel heat shield, trim sealed to seal out hot engine air, and a custom aFe brand cotton filter.

By removing your stock intake air box, you are removing the most restrictive portion of your Z4's intake system, increasing both horse power and torque, improving acceleration as well as throttle response.

aFe is among the first intake manufacturers to offer a dry filter option on their intake kits. The Pro Dry S filter in this intake kit has an oil-free filter media that flows better than stock paper filters but requires less maintenance than alternative oiled filters. For cleaning, the dry filters need only to be brushed off and cleaned with the approved aFe Restore Kit. For maximum power gains, we recommend the Pro 5 R oiled filters. The oiled filter will flow better but will need occassional re-oiling as part of a regular maintenance schedule.
