Supertech Uprated Valve Kit | Megane Mk3 RS 250, 265 & 275 | Renault F4R

Uprated Supertech valve kits for Renault Megane Mk3 RS (250, 265 and 275).

Supplied in kits of 8x valves.

Exhaust valves are supplied with a set of Supertech single groove valve keepers for the 6mm stems (part number KPR-6S-7-20)

Intake valves are black nitrided and exhaust valves are inconel.

Compared to OEM valves, the black nitride coating on the intake valves provides a lower friction interface with the valve guides and the inconel material the exhaust valves are made from is able to better withstand the high temperatures the exhaust valves see under normal operation.

Supertech part numbers:

RIVN-28338-1-8 - std size - intake - 32.3mm

REVI-28338FS-2-6-8 - std size - exhaust - 29mm (6mm valve stem)
