hi all,

im after a set of plugs for my AU series 2 VCT engine thats going in an EF XR6 and after a quick look on the NGK site im a bit confused

they have two plugs listed,
ZGR6B-11 normal plug with a 1.1mm gap
BPR6EIX-11 iridium plug with a 1.1mm gap

now i read that if i use the AU11 coil pack i need the plug gap to be 1.3mm because of the stronger coil pack but NGK dont list a plug with a 1.3mm gap for an AU series2 XR6 so can i just gap the normal plug to 1.3mm? or have i been mislead into thinking i need a plug with a 1.3mm gap when i only need a 1.1mm gap?

any help would be great, thanks guys.

im running the BPR6EIX-11 iridium plugs in my au3 vct engine thats in my ed..
they run fine.. although now gapped down to .9 for boost..

but you can run them at the 1.1mm instead of the said 1.3 it wont really make a difference...

thanks TROYMAN

i got it sorted now.
