In reply to a message from Weston Keyes sent Sat 23 Aug 2008:
Although you might be able to make the car run OK with the NGK
plugs, Jaguar calls for Champion N9YC plugs for the V12 XKE. I have
always had good luck with them. I have had running problems on cars
in the past and changing to Champion plugs have cured the problem.
Why would anyone not want to run the plug that the manufacturer
recommends, especially when it is a quality plug?–
The original message included these comments:
Hello Folks,
I am working on a V-12 that has NKG BP5ES plugs. It is running rough and the plugs look OK but thought I would replace them as a matter of course. The engine has 90K miles. Should I stick with NKG or is there another brand that might do better?
Many thanks
