|

Hi all
I am interested to know what spark plugs people are using in their 3L cars? I've had Champion D16's in mine, but they may be a bit cool.
Many thanks in advance

I always used to use NGK A6 (or AB6)
Recently on my revised engine (4½ block) I'm using 14mm NGK BPR5ES which have been faultless. |

Thanks John. That A6 is the same as the Champion D16 - or at least very close |

I've used AB6 for some time now because A6 seem no longer to be made.
My recollection is that some people suggested not all NGK plugs were genuine and there is some way of telling from the printing on them or the boxes. |
