I'm confused here...
I've been looking into spark plugs for the GDI. The service manual specifies the NGK IZFR5B plug, which seems to be made specially for the 2.4 GDI engine.
However, the service manual specifies the gap at 0.55-0.65mm, with a maximum of 0.75mm.
However, NGK state that the IZFR5B is a 0.8mm plug
Who's right?! I can't help feeling that 0.55mm is outrageously small, and the plug is specific to this engine so should be set right from the factory?
