Exhaust Valve - BMW M54 / E39 / E46 / E53 / E60 / E83 / Z3 / Z4 (many models check fitment) | 11347505731-AE

Standard: 30.5 x 5.94 mm

The AE range of high quality valve-train components includes application-specific valves, design and manufactured to OE standards.

The top-engine environment is increasingly hostile, due to turbocharging and other techniques for CO2 reduction. Only components that employ OE design expertise, with the latest advanced materials and manufacturing quality, can provide the performance and durability that professional engine technicians demand.

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 optimized for strength and temperature resistance and the stem optimized to resist wear.

Features and Benefits:

• OE Quality
• Optimized for strength
• High temperature strength
• Stem optimized to resist wear
