Supertech Upgrated Intake & Exhaust Valve Set Megane 3 Rs

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.

Can be fitted with either STD or Uprated Valve train components i.e. Spring caps and collets.
