"Oil-Free" ProDry S Filter

This intake kit replaces your restrictive factory air box. It features a 16-gauge powder-coated steel heatshield that blocks hot air from entering the filter. Each intake kit has a custom application-specific aFe cone filter that replaces the stock panel filter. The larger aFe filter, combined with the heat shield allows more air to flow to the engine. By removing your stock intake air box, you are removing the most restrictive portion of your intake system, increasing both horsepower and torque, improving acceleration and throttle response, and producing a more-aggressive engine note. Step-by-step instructions for a quick and easy install are included. aFe reports a gain of 11hp and 10ft/lbs of torque on the Z4 M.

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.

This aFe intake kit fits all 2006+ MZ4 including:
2006-2008 E85 MZ4 BMW M Roadster
2006-2008 E86 MZ4 BMW M Coupe
