Show original supplier description
This set features oversized intake valves with a 36.00mm head diameter and a 30.50mm exhaust head diameter, significantly improving flow rates. The waisted stem design further enhances this by allowing a greater volume of air and gases to enter and exit the combustion chamber as the valve extends. The construction utilizes SUH35 Heat Resistant Steel for the intake valves and Inconel 751 Alloy for the exhaust valves, ensuring extreme durability and resistance to high temperatures and power applications. The optimized head, face, stem, and lock groove designs contribute to superior sealing performance, efficiency, and longevity under demanding conditions. This racing valve set is specifically designed for the 2017-2021 Honda Civic Type-R and the 2023+ Honda Civic Type-R models. It is intended for use in high-power applications and is considered a race-spec component.
