Default 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.

What are the OEM plugs? Why those.

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.

Which iridium?

Is there a different part number for the supercharged since it is running hotter?
