What is the best spark plug for my XJR ?
Opinions ?
The kenne bell site says they have tested lots and the Denso U-groove performed well and held up well the longest, longer than iridium tipped.

I'm looking for the best performance 1/4 mile wise.
I have the NGK iridium in my wifes XJ8 with no issues.
I was curious if there were things people liked better...
I see Eurotoys sells the densos.
