Engineered to eliminate the pneumatic bottlenecks found in the stock S58 airboxes.
Features a unique air diffuser and pre-installed foam to ensure that protecting your car doesn't come at the cost of cooling efficiency.
This upgrade is specifically engineered to overcome the thermal limitations of the factory BMW S55 cooling system.
This kit replaces the restrictive and failure-prone factory cooling components with high-volume, all-aluminum alternatives to bypass the thermal bottlenecks of the F8X chassis.
This system maintains lower intake air temperatures (IATs) even under high boost or extended track sessions.
The ideal solution for BMW enthusiasts looking to build a custom oil cooling setup for the S55 engine.
