Vargas Billet Coolant Port Block-Off Flange - BMW S58 Engine

Product Details

Simplify your BMW turbo build with the VTT-FAB-041-P Billet Coolant Block-Off Flange. If you are moving away from the stock turbo configuration, the factory coolant routing often becomes redundant or physically interferes with new hardware. This CNC-machined flange provides a professional-grade closure for the front cylinder head coolant port, ensuring a leak-free seal even under high-pressure cooling system demands. The added 1/8' NPT port makes it a dual-purpose component—acting as both a secure block-off and a convenient data-logging point. It is the perfect finishing touch for builders who prioritize a "tucked" engine bay aesthetic and high-performance reliability.

Key Features

• CNC-machined for a perfect, airtight seal against the cylinder head.

• Integrated 1/8' NPT port provides a clean mounting point for aftermarket sensors.

• Simplifies custom plumbing by removing unnecessary factory water lines.

• High-strength billet construction prevents the warping or cracking common with plastic or thin-stamped parts.

• Sized for late-model BMW engine architectures (S58/S55 compatibility).
