aFe Magnum FORCE Stage-1 Pro 5R Cold Air Intake System - E85/E86 Z4 M Roadster, Z4 M Coupe

Maximum Flow Pro5R Filter

This intake kit replaces your restrictive factory air box. It features a 1.6mm powder-coated steel heat shield 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 Pro 5 R oiled filter, combined with the heat shield, improves airflow by 90%! 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.

This version uses aFe's highest flowing filter - the Pro 5 R. This filter uses a 5-layer, lightly-oiled cotton gauze material to filter out dirt and particulates, while improving airflow through the intake. For the best flowing filter, with the best performance gain, we always recommend the oiled aFe filter over the dry versions. The Pro 5 R filter is washable and re-oiled using aFe's approved Restore Kit.

This aFe intake kit fits all 2006, 2007, and 2008 MZ4 including:
2006-2008 E85 MZ4 BMW M Roadster
2006-2008 E86 MZ4 BMW M Coupe
