Exhaust Valve +1mm by Cosworth
At Cosworth, our +1.0mm large diameter exhaust valve greatly aids in improving exhaust air flow out of the cylinder head. These unique exhaust valves are machined from Iconel, which we aggressively tested with heat up to 2400 F to prove that it could handle continuous high temperatures. Material reliability paired with our swirl polish to ensure smooth air flow and dished face for added weight reduction, provides a durable and essential component for your high power build.
