VAC Performance Valve Kit (BMW S14) (VAC-HPVK-S14)

Put Formula-1 based engineering in your N54 powered BMW!

Why should you use VAC High Performance BMW Valves and Spring for your advantage?

We use them ourselves!  Installed thousands of race engines, and street engines for years with nothing but excellent results!

Why is this kit the best?

Valves:

• One piece design (compared to 2 piece welded valves which typically fail at weld)
• Use of single-groove keepers (locks) as is popular with racers and builders (not pictured)
• Lightweight engineering enhances performance and increases valve train component longevity
• Low-friction coated to preserve valve guide bore
• Enhanced resistance to fatigue from heat and high RPM

Springs:

• Designed with the aid of a Formula-1 engineer!
• Made from H-11 Alloy. This metal is often used for highly stressed structural parts such as aircraft landing gear and still offers resistance to thermal fatigue.
• Shot-peened springs for stress relief and dual-interference fit to control harmonic resonance across the rev range.
• Dual-Spring Interference configuration offers the advantage if should something happen to one spring, the other can prevent the valve from dropping and causing catastrophic engine damage.
• 12,000 RPM rev-handling for added peace of mind and maximum performance

Use our VAC High Performance BMW Valve Spring and Valve Kit to extract the most from your high performance build!
