XKE sparkplugs
#5
If yours is the 4.2 triple SU engine, the original specs (assuming the original petrol and ignition components) called for Champion N.11Y, gapped at 0.025". I think the current equivalent is the Champion RN11YC4. Lots of folks use the NGK BP5ES - I'm doing a regular service on mine next week, and that's what I am installing. That 0.035" gap is a bit ambitious, unless you have more 21st century ignition zapp mods compared to what was original to this ignition system. My car is stock except for Mike Eck's Points Saver Deluxe black box. I'm gapping mine at 0.030".
I'm not familiar with the later twin Stromberg engine, so that may be different. Spark plugs are a bit of a religious issue, so your results may differ.

Restoring 1967 xke 2+2
I'm installing a Pertronix distributor and coil with Accell wires. I'll be using the NGK's BP5ES gapped at .35 for initial setting. I've been running Bosch plugs in all my other vehicles and rec vehicles with no problems. I decided to use the NGK's from input from this forum and others. Thanks all.
