Smile Spark Plugs
Just a short bit if information needed from others experience.

What spark plug and coil life can be expected in the 2000 XK8?

And what plug is recommended?

Thanks guys.

I saw an improvement at 71k. No reason you couldn't wait longer though. Used Imodium plugs 0.052 gap.

My 1999 XK8 convertible just passed 129,690 on the original coils, runs like a dream.
