Wossner Forged Valve Set to suit most 2.0 F4R Engines.
These kits are supplied in sets of 8 (inlet or Exhaust) with 2 options for the exhaust valve material. The intake valves are forged 1pc steel construction and the exhaust valve sets are available in forged 1pc steel or Inconel options.
If you require a full engine set you will need to add both the Inlet valve set and your choice of exhaust valve set to the basket.
As a guide we would recommend steel exhaust material in any atmospheric engine and forced induction engines up to 300 BHP. Over this the we would recommend using the Inconel exhaust valve material for higher power / temp forced induction engines.
**Please note these valves feature an altered collet height to help prevent the retainer bottoming out on higher lift cams. Due to this it is always recommended to use an uprated valve spring set. Either the Catcams or Supertech sets are suitable, but please feel free to contact us if advice is needed.**
These sets are not suitable for the Megane 3 RS!
