D7F726 or D7F720

[Gaz.]

Trying to sort out some spark plugs for Soph's X Reg (2000) 1.2 8v. Problem is, this is the changeover year between the D7F 726 and 720 engines, so her reg brings up both codes on various parts systems. This then throws up NGK BKR5 or NGK BKR6, dependent on the engine.

Had a look on the sticker in the driver's door but couldn't fathom the engine type, so is there any way of telling them apart?

I don't have her V5 so can't look on there for an engine code.

the difference is only one heat range so wont notice on the vast majority of cars. Go for the 5's

Figured as much but wanted to double check. Thanks Danny.

EDIT: It brings up BPR6 not BKR6, but the Iridiums come up as BKR5EIX and BKR6EIX, so I'm going to presume they're all the same fitment.
