Maxiumum Flow Pro5R 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. Stage 2 intake kits also feature a heat-resistant plastic-molded intake tube that smooths airflow into the throttle body, improving airflow and throttle response. Each intake kit has a custom application-specific aFe filter.

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.

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 2006, 2007, 2008 Z4 models (E85, E86), including:
2006-08 Z4 3.0Si Roadster, Coupe
