VAC Motorsports High Performance Valve Kit, BMW M50/M52/S50/S52, 6mm Valve

VAC Forged Stainless Steel Valves are precision made to exacting specifications and are suitable for both street and race vehicles.

They work great in street vehicles for day to day use where engine build up and byproducts can harm typical "race valves." These valves have also proven their worth on max performance race engines, surviving lap after lap, race after race, for multiple seasons without being replaced.

Our valves feature:

Single piece forged stainless steel design

Application for original 3 groove keepers/locks

Lightweight engineering; enhance 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.
