When we first got our hands on a E46 M3, we were eager to release our CSL Intake. After popular demand, the experts here at Turner took it upon themselves to make a more affordable intake option. Our engineers took the original stock intake and made it better. The intake system we designed outflows the factory intake, maintains factory MAF scaling, provides increased induction noise, and looks great in the engine bay. Our intake was CAD designed inhouse to seamlessly integrate with OEM inlet ducting and stock mounting locations.
Through rigorous research, development, and testing of this intake, Turner has created their perfect version of an "Open Intake" that flows more freely than the stock intake, providing options to suit your needs for a cost-effective solution. Flow bench tested in-house at Turner, the Turner E46 M3 intake flows more air than the OEM M3 Factory intake.
Features:

Wrinkle Black Powdercoated Heat Shield Assembly with pre-installed edge trimming.
Precision fit heat shield provides fresh cool air to the intake while keeping hot engine bay air out.
Heat shield mounts in stock location with supplied hardware
Maintains OE fresh air inlet scoop.
Aluminum MAF housing maintains OEM MAF scaling.
4" conical hi-flow reusable air filter; featuring 8 ply oiled cotton gauze construction and a bell mouth inlet to maximize flow and filtration efficiency

Performance:
