Description

Upgrade your engine with Supertech Black Nitrided Stainless Steel Intake Valves. BMIVN-1055S fits the BMW N/S55 SS Black and is sold as a single unit.

Supertech Black Nitrided Intake Valves are forged from high-grade stainless steel and treated with a proprietary black nitride surface finish. This advanced treatment increases surface hardness and resistance to wear, corrosion, and carbon buildup while reducing friction between the valve stem and guide. The go-to upgrade for performance builds on naturally aspirated and forced induction engines that demand longer valve life and improved flow consistency over OE valves.

• 1-piece forged construction for maximum strength
• High-grade stainless steel base material
• Black nitride surface treatment for increased hardness and wear resistance
• Reduced carbon buildup and stem-to-guide friction
• Corrosion resistant finish for long service life
