New spark plugs and coil gaskets
I am planning to replace the spark plugs in my 95 4.0L XJS. Do I need to replace the ignition coil mounting gaskets (see pic) as well?
Autohausaz.com suggests to replace the gaskets when replacing the spark plugs. Apparently, the gaskets costs ($6 each) more than the NGK plugs ($1.7 each).

I thinky they're there just to keep dirt out. I might be wrong on this but I think the Jaguar catalog refers to them as "dust excluder gaskets".
Since the coil cover itself has a gasket I wonder about the necessity having a gasket for each coil as well. A couple of mine are missing entirely. If something bad is supposed to happen from lack of a gasket I haven't experienced it.
Other will chime in.

I strongly suspect that spending $6.00 each for coil gaskets that should be 75 cents each is something the OWNER will love and the car could care less about.
I certainly appreciate the feel good factor, though, as I've spent a fortune on "feel good" parts for my three Jags. Coil gaskets are one of the areas where I draw the line.....sorta like those $7.50 ice cream cones at the designer creameries :-)

It's $40, and if it didn't cost 4x more than the spark plugs, I wouldn't be complaining.
I have a 2000 Ford Taurus that also uses the coils, and there is no gasket. I'm not sure there's another vehicle out there that requires a gasket. When I went in to a local parts store (not a chain, but a mom&pop) and asked for a gasket for my coil, they looked at me like I had three heads.
They tried to pull something up on the computer, but couldn't find a coil gasket for any car.
I think someone overengineered this thing. I would have appreciated it if they spent more time picking a paint that wouldn't flake off at the engine cover, than design a gasket to prevent a problem that doesn't exist.
