Vargas High Flow Catch Can System - BMW G8X M2, M3, M4

Product Details

Included as a core component of the G8X High-Flow kit, the VTT Billet Oil Cap Adapter is the essential link for owners utilizing their OEM valve cover in a high-performance environment. This precision-machined adapter replaces the plastic factory oil cap, converting the fill point into a high-volume ventilation port. By transitioning from a standard cap to a -16 AN interface, it allows for a direct, high-capacity path from the crankcase to the catch can. This setup is vital for S58 engines that require more venting than the factory PCV system can provide, effectively reducing "crankcase puff" and improving turbo oil drainage by eliminating backpressure within the block.

Key Features

• OEM Valve Cover Compatibility: Designed specifically to fit the factory BMW S58 valve cover notches for a perfect, gasket-sealed fit.

• Maximum Throughput: Converts the restrictive oil fill neck into a wide-bore -16 AN outlet to facilitate rapid pressure release.

• Billet Construction: Machined from a single block of aluminum to ensure it will never crack or leak under high thermal stress.

• Low Profile Design: Engineered to maintain clearance for the engine cover (where applicable) and surrounding intake plumbing.

• Leak-Proof Sealing: Utilizes high-quality O-rings to ensure a vacuum-tight seal against the valve cover, preventing oil weeping.
