Thread: What threaded tip style spark plugs to use?

Looking for some info on terminal types. I can no longer use the standard 'Solid Terminal' end types, due to COP conversion. I figured out that I need either an 'Loose Terminal' that has a removable cap, or a 'Stud Type' (pictured above) that comes just with threads.

Searching for this info online is hard, since most retailers don't list what the type is. I would like to get something close to an NGK BKR7EY-11, but this seems really difficult.

Anyone here ever researched this?

I run the Denso plugs, the tips are screw type but there crimped. Be careful on the bench grinder there easy to remove

Got a part number?

I use IKH24 in my VET. H is for long thread. So look at the IK22 for short thread in 7 NGK heat range equivalent if your not using the vet or 20v head.

What type brand of cop requires this? Never seen this before.
I'm currently trying to go cop with gsx-r1000 coils and aem ems
