Are these spark plugs good for a 2001 Jaguar S-Type? my Jag has 113K Miles, the previous owner never changed them so i think it is time before i start having problems.

Now are these good for my Jag?

I got this Jag with 108K miles and had the tranny rebuilt and oil changed at 110K(which everyone here helped me with), i already replaced the air filter, fuel filter and brake pads because the previous owner never did maintenance on it.





I really like this car and want to keep it running good. I still have to fix the heater, the drivers window doesn't roll down and the reverse parking assist light is stuck on OFF.

 

That's a sharp looking S-type.

 

Definetly go with the Iridiums. The coil link is removed. Rock Auto.com has great prices on both.

Since you haven't specified which engine you have, there may be a few more "cheap" parts that you want to replace as well.

I also agree, beautiful vehicle!

 

Listen to the suggestion about replacing some other parts once you get the manifold off for the plugs. Lots of threads on how to do it. Worth doing considering the parts are not expensive.

 

Def replace the coils!! i just did mine with 90,000 miles on them. Nice Jag!!

 

If there is oil around the plugs all valve cover gaskets should be added to th list!
