RACING VALVE SET VR38DETT

Tomei began operations in 1968 as a race car tuner in Japan. Tomei's racing heritage means their research and design team have first-hand knowledge of the extreme demands racing puts on an engine. Using only the highest quality materials means that Tomei's products can handle the intense strain and heat a purpose-built engine will experience whether it be on the street or the track. Tomei's attention to detail is second to none. All of their products are thoroughly researched and engineered to achieve optimal efficiency. Because even minuscule differences in measurements can cause catastrophic engine failure, all Tomei products fall within strict tolerances. Tomei machines all of their engine components to enhance airflow and ensure proper fitment and seal. Engines require as much fuel mixture to enter the combustion chamber as possible. For that reason Tomei has selected a larger diameter design to optimize flow rates. Due to the extremely high-temperature conditions experienced in the combustion chamber during high power runs, the durability of the valves was also addressed to improve resistance to high heat conditions. Tomei oversized valves are manufactured with the highest quality materials available to ensure they will perform in demanding conditions. Oversized valves were designed for increased flow efficiency on both the intake and exhaust side. The stem has a thinner design for maximizing airflow rate within the port with the reduced airflow resistance. This design also means the end product is lighter than the factory pieces. Ultra durable, Heat Resistant Race Spec Valves Designed to withstand high power applications.
