Does anyone have industry knowledge about spark plugs?
I'm really confused about what spark plugs 500x 1.4L turbo is supposed to use:
Service manual states gap 0.65mm (0.026"), but gives no part number
Ones I pulled out car were: NGK FPT 55249868 supposedly 0.7mm (0.028")
Ones I used replaced them with while back were: Bosch YR5D33S 96320 at 0.7mm (0.028")
Recently I've installed Denso IXU27 at 0.9mm (0.035")
but all of these are supposed to be compatible with Magneti Marelli 062120137312 which are gapped at 1.0mm (0.039")
