Function: Intake and exhaust valves help improve the efficiency of the engine's intake and exhaust. Smoother air intake enables the engine to draw in more air, which improves combustion efficiency and increases the engine output and torque
Quality Material: Intake valve kits adopts high-strength alloy steel. It can withstand the high temperature and high pressure environment inside the engine as well as frequent mechanical impacts, and has good abrasion resistance and fatigue resistance to ensure that the intake and exhaust valves maintain stable performance in the long-term use of the process
Package Included: 12 Intake Valves (1 Groove; Head 37.30mm x Stem 5.95mm x Length 101.35mm); 12 Exhaust Valves (1 Groove; Head 30.60mm x Stem 5.95mm x Length 97.20mm) to ensure smooth and reliable operation
