New E46 M3 Turner Performance Air Intakes

The CSL Intake for E46 M3 is a flagship Turner product. We've seen incredible success with that project, however, there was still an appetite for something more simple and more affordable from many of our customers that are still eager to hear more of that S54 induction. The open intake design seamlessly integrates the OE fresh air scoop and also leverages stock mounting locations. The 4" conical filter helps provide significantly more S54 noises than the stock airbox. The wrinkle black finish looks right at home in the engine bay, and the heatshield is completed with the Turner Logo Plate.

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

This complete kit includes everything (except a tune) to completely transform your M3 in an afternoon. *Will require the use of an Alpha N tune*
