Thanks

Simon.

There are dozens you could use.

Regular old BCPR6ES etc are perfectly fine or you could go to fancier stuff.

I bought the genuine replacement plugs from Monkfish. Probably good for 50,000 miles.
I did price them up at Vauxhall years ago, I think they wanted £22.00 each! I often wonder how they are still in business?
From what I remember there are a few makes of copper plugs suitable for an LS1, but they don't last as long.
