Supertech High Performance Valve Kit, BMW M50/M52/S50/S52

Supertech Forged Stainless Steel Valves are precision made to exacting specifications and are suitable for both street performance and full Race vehicles.

Supertech valves have been proven to work great in street vehicles for day to day use where engine build up and byproducts can harm typical "race valves," yet these valves have proven their worth on max performance all out race engines, surviving lap after lap, race after race, and even multiple seasons without being replaced!

As the M50 and S50 engine are under 3-liters, they typically breathe fine with most camshafts on mild builds, but since the S50us and S52us sepc M3 engines use the same heads and valves, we have found great gains when fitting even mild S50 and S52s with these better flowing, and lighter weight valves.

Supertech valves feature:

• One piece forged stainless steel design (compared to 2 piece welded valves which typically fail at weld)
• Triple or Single groove stems to go with your application.
• Stock and Oversize available
• Lightweight engineering: enhances performance and increase valve train component longevity
• Low-friction coated to preserve valve guide bore
• Enhanced resistance to fatigue from heat and high RPM

• 1995 and older engines are recommended to get our upgraded locks
• These valves are a must-have when building a high performance and very high revving engine: They dramatically reduce valve weight and this improves valve train reliability greatly as the valve springs do not have so much mass to control. Crucial on the M50 family of engines like these.
• Over-sized valves can help enhance maximum engine output, a great upgrade with 264/256 and larger cams.
