Anybody know of any suitable looking rubber boots that fit these caps out there?
I’ve seen a few different styles, here’s just one example…:

I looked at Green Spark Plug Co., but couldn’t seem to spot anything, unless I’m not navigating their site properly. (It’s entirely possible!)

Because they’re installed over the plug cap itself, I’ve measured the cap at that end to be approx ~13mm at the little end flange, so I guess I’m aiming for an internal diameter at the plug cap end of the boot to be around ~12mm and then 7mm at the other for the spark plug wire.
Any suggestions welcome…
Cheers
