Spark plugs, alot of different part #s

I read several posts and it's different part numbers people said are the best, but not sure which one?

NGK Iridium IXBKR6EIX-11, BKR5EIX-11, and on NGK website it shows NGK PFR5G-13E.

Which is the correct spark plug to get with the proper gap?

I believe the recommended plugs are NGK (5464) BKR5EIX-11 Iridium IX

I recently purchased mine on Amazon for my 2001 VDP.

They are packs of 4 so you would need two packs.

Never trust pre-gapped plugs, you always check the gap.

But . . . if I understand correctly from the NGK Iridiums I have used, these modern spark plugs are not constructed with overarching (and adjustable) body electrodes, so there is no facility to adjust the gap. This makes getting the correctly gapped plugs, as the OP asks, as important.

Best wishes,
