VTT Billet Oil Cap Crankcase Vent Adapter - Screw In - BMW S58, B58TU, B48, B46

Product Details

Engineered for the enthusiast who demands total control over their PCV system, the VTT Screw-In Oil Cap Adapter provides a robust solution for custom crankcase ventilation. This version of the VTT adapter is purpose-built to thread directly into VTT's proprietary Billet and Cast valve covers, ensuring a leak-free seal under the most demanding racing conditions. By utilizing a large -16ORB interface, users can customize their evacuation setup with anything from low-profile 90-degree fittings for tight hood clearances to massive -20AN lines for maximum displacement of blow-by gases. It is the ultimate tool for builders looking to integrate a professional-grade catch can or breather system into their S58, B58TU, or B48 platforms.

Key Features

• VTT VC Compatibility: Optimized specifically for VTT’s own line of aftermarket valve covers.

• Crankcase Pressure Relief: Eliminates the bottleneck of factory PCV systems, preventing "pumping losses" and protecting engine seals.

• Integrated Droplet Separator: Internal venting design acts as a primary stage filter to minimize oil migration into the ventilation lines.
