ScienceofSpeed Engine Intake & Exhaust Valves

ScienceofSpeed offers lightweight high strength forged intake and exhaust valves for the S2000. 

Manufactured exclusively for the S2000, these valves feature a weight reducing dish. The intake valve features a tapered stem and swirl polished head which increase air flow speed and fuel atomization for maximum performance.

Valve train weight reduction offers several benefits including a higher rev potential of the engine, reduced horsepower loss from inertial loss, and the ability to run lower valve spring spring rate leading to increased camshaft durability.

Valve widths and lengths are within factory spec allowing these valves to be compatible with the factory keepers, guides, and guide seals.

Valves sold as a complete set (8 valves per intake or exhaust set).
