The Eventuri Z4 B58 intake system consists of a series of components designed to perform a specific purpose and manufactured to the highest standards. Made from 100% pre-preg carbon fiber with no fiberglass, it features a smooth internal surface that maintains smoother airflow.
Each intake system consists of:
Dual-feed carbon fiber airbox
Custom-built high-flow dry cone filter
111mm ID carbon fiber inlet pipe
CNC-machined temperature sensor mount
CNC-machined breather adapter
Gold-reflective heat shield
Laser-cut stainless steel brackets
Silicone coupler with OEM-spec clamps
Dual-feed carbon fiber airbox Air Intake
Made of prepreg carbon fiber, the airbox seals the filter from engine compartment heat and provides a dual supply of cold air. Since the airbox is positioned next to the exhaust manifold, it is crucial that the filter be completely sealed: therefore, the airbox was designed to encapsulate the filter while providing a large internal volume. To seal the intake pipe, a laser-cut plate with a rubber sealing strip that attaches to the airbox was designed. The intake pipe passes through the plate, and the rubber seal ensures that heated air does not enter the airbox. To further reduce heat absorption, an additional heat shield with a gold reflective layer is placed on the side of the exhaust manifold, effectively combating radiant heat transfer.
