E9x M3 Intake
Advanced Flow Engineering
Info: afepower.com
Like any car, getting more air to flow through the M3's 4.0L V8 greatly enhances its performance and capabilities. So aFe's Stage 2 intake features either the Pro-5R cotton filter or Pro Dry S synthetic filter for better flow. It also utilizes the stock air box (cutaway in this photo) to keep temperatures down and provide a stealthy look under the hood. aFe claims gains upwards of 18hp and 15 lb-ft of torque, which we hope to verify with our Project M3 very soon.
