Designed for high-performance builds, these GSC Power-Division Manganese Bronze Intake Valve Guides provide superior thermal conductivity and wear resistance for BMW B58, S58, and Toyota GR Supra engines. These guides are a critical upgrade over factory components, especially in high-boost or high-RPM applications where valve stem heat management is essential to prevent seizing or premature wear.

Each guide is precision-machined from a proprietary manganese bronze alloy, offering a lower coefficient of friction than standard OEM guides. The integrated stopper design ensures consistent, repeatable installation depth during the cylinder head assembly process, removing the guesswork and ensuring proper valve stem geometry.

  • Proprietary manganese bronze alloy for enhanced heat dissipation and durability
  • Integrated stopper for precise, consistent installation depth and alignment
  • Lower friction coefficient than factory cast iron or steel guides
  • Designed for use with high-performance stainless steel or titanium valves
  • Set of 12 intake valve guides
  • Manufacturer Part Number: 3132-12
