I'm new to the board, and noticed that the only forum marked for XJRs is marked for the V8 cars, 98 and later.
Seems like this is the place for my straight six and I, right?

 

Excellent! I have a question regarding spark plugs: What temp are the factory plugs? I'd like to go a bit cooler, but I'm having difficulty finding where to start. I'm also interested in what you've all been running, and what has worked.

I'm also afraid that I may have a faulty coil pack or two, is there a resonable source for these? Options other than Jaguar/Lucas?
Many thanks!

 

That's not "terrible", but I'm not seeing a brand on it....which tends to make me nervous with bargain parts.
