Engineered for extreme boost pressure and high-rpm reliability in high-performance Nissan RB26 engine builds.
Product Overview
The Brian Crower BC3235 exhaust valve kit features 12 premium one-piece stainless steel exhaust valves manufactured with a +1mm oversized head diameter (31.15mm) specifically for the Nissan RB26DETT engine platform.
