Air Flow Perfection.
Our Super Alloy Exhaust Valves are for those running high BHP, high EGT setups that need a valve that will last in 1000c conditions. The Super Alloy Exhaust valves have chrome polished stems to create a smooth, durable finish for added life and better lubricity, especially when paired with Our Manganese bronze valve guides.
Under the head, the dish is maximized for weight savings while swirl polished and back cut heads promote better airflow without sacrificing durability. Available in Standard Size 32mm and 33mm oversized.
