Exactly like stock, but with 289% of cross sectional and thus 289% of the original air flow to engine intake. Talk about removing bottlenecks from performance!
Fits to S50, S52 and S54 Z3M Roadsters and Coupes, and every other Z3 with Z3M bumper. Includes outside temperature holder and brake cooling functions just like stock.
NOTE: Use in conjunction with Erik Eriksson Design Z3 / Z3M chassis specific upper engine room parts: For example 4" Z3 / Z3M outlet vent, 4" Z3M CSL horn or 4" Z3M CSL Snorkel.
