Zetec turbo spark plug recommendations please
As title
Anyone recommend me some, or is it worth machining the head to accept Cossie type ones?
Thank you please

Most of the massive power Zetecs seem to use Cossie plugs, but below 450 standard plugs are fine.

Doesn't this cause the head to blow out where the plug sits due to machining it close to a water jacket or oil way ? A mate of mine had the done to his head and it blew the plug clean out of the head

It does get closer but not heard of one failing. I know Lee did this mod on his 592bhp engine, but he machines it so the plug sits higher in the head as well. He did this on his old 450+ bhp engine and Alex's old engine, and they both took an absolute caining!
Pic of a cross-sectioned head Lee had done shows the clearances.
