Supertech Performance BMIVN-1033SL High-Performance Intake Valve

The Supertech Performance BMIVN-1033SL is a high-performance intake valve engineered for superior flow, durability, and reliability. Backed by over 20 years of manufacturing experience, Supertech works closely with professional engine builders to continuously refine their valve lineup, ensuring each component meets the demands of high-performance and competition applications.

Key Features:

• One-Piece Forged Stainless Steel Construction — Manufactured from EV8 (21-4N) stainless steel alloy for exceptional strength and long-term reliability under high-stress conditions.
• Black Nitride Coating — This hardening surface treatment produces a smoother finish than traditional chrome, reducing friction between the valve stem and guide for improved longevity and performance.
• Chrome Coating Option Available — A widely adopted solution in performance valve applications for added surface hardness and heat resistance.
• High Flow Design — Optimized geometry promotes maximum airflow into the combustion chamber, supporting power gains in naturally aspirated, turbocharged, and supercharged engine builds.
• Sold Per Valve — Order the exact quantity required for your engine build (e.g., order 16 for a 16-valve engine).

Supertech valves are available in a range of materials and alloys to match specific engine requirements. For extreme-heat exhaust applications — such as turbocharged or supercharged engines — Supertech also offers Inconel 751 nickel-base alloy valves in their lineup. The BMIVN-1033SL is the intake-side solution designed to deliver consistent, high-quality performance across a wide range of engine platforms.
