Correct spark plugs for au xr8

[redauxr8]

Im buying some MSD leads and coilpacks for my AU.
Does anyone know what the correct code for the sparkplugs are?

I was under the impression that it was : BPR6EFS-13...... But someone else told me that it was BPR5EFS-13..... Anyone know which is correct?

Cheers

This should be a good starting pint.

Either one is ok, No.5 is the stock heat range, the no.6 range plug is one range colder. Ford went with the hotter plugs to get a complete burn at idle and meet emission targets. But this contributes to pinging on some cars. I have been running the no.6 plugs for 9 yrs now as this was the advice I got from Michael at ICE ignition.

Only lists TR55IX Iridiums.

I run BPR6EFS13 - same as the last Holden 308 EFI.

Thanks for your help everyone.

Any hints on getting plug five out safely with 4001s?

Use spark plug socket with a shifter on the end instead of the ratchet handle.
