Uprated Forged Valve Set for the Renault F4R Engine. STD and Oversizes available
A common fault with the F4R is the 2 Piece valves that can break on the high performance engines. This inturn makes a mess of the engine and usually results in a scrap cylinder head and piston.
This uprated valve set is suitable for both High RPM for N/A applications and extreme heat from Turbo applications. They are a single piece forged construction.
8 - Uprated Stainless Inlet Valves (nitrided)
8 - Uprated Iconel Exhaust Valves
8 - Sets of Collets (locks) required for Exhaust valves.
Can be fitted with either STD or Uprated Valve train components i.e. Spring caps and collets.
Want a big valve head? We now offer oversized valve sets (+ 1.50mm Inlet and +1.00mm Exhaust). Select this option before adding to the basket. Please note that additional head work is required to fit oversize valves.
