Product Description

The GSC Power-Division 2092-12 intake valve set includes twelve 30.1 mm head diameter valves engineered for high-flow performance in modern turbocharged B58 and S58 engines used in Toyota Supra and BMW platforms. Chrome-polished stems reduce friction within the valve guides, while swirl-polished, back-cut heads promote improved airflow for more efficient engine breathing and performance. These valves are constructed from modified 21-4N stainless steel for strength and durability under high boost and elevated RPM conditions.

Designed as direct replacements for OEM intake valves in vehicles such as the Toyota Supra 3.0 L B58 and BMW Z4/M3/M4 with B58 or S58 engines, the GSC 2092-12 set is ideal for engine rebuilds, performance upgrades, or high-output applications. Professional installation with correct valve springs, seals, and retainers is recommended for best performance and long-term reliability.
