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.
Each kit includes 8 Exhaust valves and 8 Inlet valves. We offer different materials to suit both Atmospheric and Turbo engines. In all cases the inlet valves are constructed from 1 PC forged stainless steel with options of Inconel exhaust valves higher temp turbo / forced induction engines.
Steel Exhaust valves - Suitable for all atmospheric engines and turbo applications up to 350 BHP.
Inconel Exhaust valves - Aimed at high temp performance turbo engines, but can also be used in atmospheric engines. Recommend for engines over 350 BHP.
Once again these are full sets of 16 and all inlet valves provided are (Stainless steel) you simply select which material exhaust valves you require.
Need advice, please ask.
All kits can be fitted with either STD or Uprated Valve train components i.e. Spring caps and collets.
Want a big valve head? We offer oversized valve sets (+ 1.50mm Inlet and +1.00mm Exhaust). Select the oversize option before adding to the basket. Please note that these are only available with Inconel exhaust valves, but are suitable for atmospheric and turbo applications. Additional head work is required to fit oversize valves.
