Let your E9X M3 Breathe

As you know, the E9X M3 is an impressive package from the factory. It delivers a driving experience like few other cars can. It still has some shortcomings from the factory that can be addressed with simple modifications, one of those being the intake system.

The two major limitations of the factory intake system are the intake elbow and filter. The biggest culprit for robbing performance is the factory intake elbow gets narrow where it bend towards the intake manifold. This design was done from the factory to cut down on intake noise and meet required NVH standards. This design is like forcing an athlete to run a marathon while only being able to breathe through a straw, it just isn't effective. The second, and only a minor hindrance compared to the intake pipe, is the factory air filter. It is designed to filter as much dust and particulates as possible while maintaining acceptable NVH. To do this it is made from extra layers of thicker materials which ends up restricting air flow.

aFe addresses the factory system with the following:

The intake charge pipe/elbow is entirely redesigned by aFe. The overall shape and routing of the charge pipe has been improved allowing air to flow more directly while the inside of the pipe is smooth which helps reduce air flow turbulence in the intake system. This redesign allows for a 41% higher flow rate than the factory piece.

This intake system is complimented with the renowned Pro 5R filter. The filter is constructed with several layers of material which progressively help filter out dust while maintaining high intake flow which your M3's engine desperately wants.

Note: Proven to produce an extra 18hp and 15lb/ft of torque
