GSC Power Division
GSC Power-Division 4B11T Chrome Polished Super Alloy Exhaust Valves - 30mm (+1mm) - Set of 8
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Designed for high-performance Mitsubishi 4B11T engines, this set of eight GSC Power-Division Super Alloy exhaust valves is built to withstand the extreme thermal loads found in high-boost, forced-induction applications. These valves feature a 30mm head diameter, providing a +1mm oversize over factory specifications to significantly improve exhaust flow and cylinder scavenging when paired with professional cylinder head machining.
The proprietary Super Alloy construction offers superior heat resistance compared to standard stainless steel, preventing valve head deformation under intense combustion temperatures. Each valve is chrome polished to a mirror finish, reducing stem friction and minimizing carbon build-up for long-term seat consistency and performance.
- Fits Engine: Mitsubishi 4B11T
- Head Diameter: 30mm (+1mm Oversize)
- Material: High-Temperature Super Alloy
- Finish: Chrome Polished
- Quantity: Set of 8
