Supressed spark plug end caps - where to buy them?

[axnutty]

Struggling to find supressed spark plug end caps. Anyone know where I can get some from? They all seem to be unsupressed

Why do you need suppressed? The leads themselves should be suppressed.

Just change to a resistor spark plug, it's all you need to do, and keep the unsuppressed extenders you already have. I cant remember the plug part number off the top of my head but BPR7ES rings a bell
