5.2 - Spark Plug Replacement ( )

Remove the cap on the engine top cover by undoing the three torx head bolts.

Working methodically along the engine, undo each epoxy cased ignition coil and gentle pull upward to free the assembly from the plug.

Use a conventional plug socket and extension bar to undo and remove the plug. Unless the engine has recently been started and not warmed up, the plugs should be a light brown/grey colour. Whiteness can indicate a lean mixture or water in the cylinder from a blowing head gasket. Dark and sooty suggests a rich mixture, but is normal when the engine has just been started and stopped when cold.

Gap the new plugs to 0.035" / 0.09mm and fit by tightening until they feel tight, but donít overtighten. Reattach the ignition modules and gently rebolt them in place. Refit the engine cover top cap.
