GSC Power-Division Manganese Bronze Exhaust Valve Guides with Stopper for BMW B58 / S58 (Set of 12) 3131-12
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Upgrade your cylinder head with GSC Power-Division manganese bronze exhaust valve guides, specifically engineered for BMW B58 and S58 engine platforms, including the Toyota GR Supra. This set of 12 guides (MPN 3131-12) provides a significant durability and performance upgrade over factory components in high-heat, high-boost environments.
- Manganese Bronze Construction: Offers superior thermal conductivity to pull heat away from the valve stems and provides natural lubricity to reduce friction and wear.
- Integrated Stopper: Machined with a built-in stopper to prevent guide migration or "dropping" into the port under extreme operating temperatures and high-rpm vibrations.
- Performance Ready: Ideal for high-horsepower builds using aftermarket valves and aggressive camshaft profiles where OE guide tolerances may fail.
- Set of 12: Includes a full set for the exhaust side of the cylinder head.
These precision-machined guides ensure consistent valve stem alignment and improved heat dissipation, making them a critical component for any serious B58 or S58 engine build.
