AE Exhaust valve

Exhaust valve
made from 214N stainless steel, diameter: 1.3/8", length: 4.1/2"
Advanced top-engine technology
Valves are subjected to some of the highest stresses and temperatures in the engine, yet not only must they survive, they must also continue to seal perfectly. As a top-engine expert with a long heritage of innovation, AE provides the answer with high-precision designs. The choice of material is so critical that some AE valves, known as ‘bi-metallic valves’, are made from two materials, with the head optimised for strength and temperature resistance and the stem optimised to resist wear.
