GSC Power-Division Manganese Bronze Stopper Style Exhaust Valve Guides for Subaru EJ205/EJ207/EJ257 (Set of 240) - B3025
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits Subaru EJ205, EJ207, and EJ257 engines.
Engineered for high-performance builds, these GSC Power-Division manganese bronze exhaust valve guides are a critical upgrade for Subaru EJ-series cylinder heads. Manganese bronze provides significantly better heat transfer than standard cast iron guides and offers a lower coefficient of friction for the valve stem, reducing wear in high-stress turbocharged applications.
The stopper style design features a machined shoulder to ensure a precise, repeatable installation depth every time. This prevents guide migration, a common failure point in high-heat or high-RPM environments. This bulk pack of 240 pieces (MPN B3025) is ideal for professional engine builders and machine shops processing multiple heads.
- Material: High-strength Manganese Bronze for superior thermal conductivity
- Style: Stopper style (machined shoulder for positive seating)
- Location: Exhaust side
- Fitment: Subaru EJ205, EJ207, and EJ257 platforms
- Quantity: Bulk set of 240
- Manufacturer Part Number: B3025
