A full set of six Supertech intake valves for the G16E-GTS, machined from 21-4N stainless steel and black-nitrided for durability and smooth flow. The upgraded alloy handles the higher spring loads and engine speeds of a built head far better than OEM, and the set re-valves the entire intake side at once. A go-to upgrade for tuned GR engines.
