spark plugs

[griffter]

Going to Halfords on the way home tonight but I forgot to check the Bible before I left this morning

I know I've got NGK's fitted at the moment but I can't remember the detail...
What plugs do I buy for my 92 4.3 please?

I use NGK B7ECS, I have just had to replace the old ones this week in the hope of rectifying a persistent mis-fire (no luck, nice waste of £32!)

Cheers.

Interesting as I'm sure mine were B6ECS - so you use a hotter plug. I was thinking of trying a hotter plug as if anything the B6's run a bit cold with the Mark Adams' ECU on my car.

Is yours a 4.3?

DOn't bother with Halfords... they don't stock them or know that they exist!!

Yep, Halfords don't stock them, or at least my local one doesn't. I had to get mine from a TVR dealer on Saturday as I couldn't find anyone who had them on the shelf. The dealer said they buy them by the hundred, as if they run out they can't get them locally either!

[griffter]

Oh bugger!

Any view on B6 vs B7?

Guess I'll take what I find when I find it then!
