NGK Plug Caps

I went on a deep google search for NGK spark plug caps the other day and thought I'd share my findings.

I ordered some NGK 8384 SB05EP Spark Plug Cap from ngk.com. I prefer the ones that clamp directly to the electrode without the nut. 16 still in stock
The P version means "with special waterproof cover". Don't know if that will cause any fitment issues, but we'll see.

I also ordered NGK 8080 SB05F Spark Plug Cap from ngk.com. Just in case the P version mentioned above has a fitment issue. 165 still in stock.

Searching by stock number helps sometimes with some retailers (found on complete chart above)

The boat websites seem to have older bike plug caps.

I have no relation with or knowledge of these retailers. Deal at your own risk.

The caps seem to be out there, but dwindling due to discontinued.

Good luck! Leave some for me!!!

You won't be the first one to have been down that path...
As for the NGK nomenclature the SB05E is for sparkplugs with the nut or solid post terminal and the SB05F is for threaded terminal.
Also note that the B stands for 14mm Ø plugs whereas plugs for the 1200 8V are 10mm Ø, they will fit just fine but an SD05 will have a better seal around the insulator.

I wondered about the D or B, but Pete Roper and Moto International suggested the B on previous posts.
I'm definitely not saying you are wrong, just putting this out there.

Besides, about all your gonna get are the Bs now it seems.
I did find some Ds on Amazon. Ships in 3 to 4 weeks. I wonder if they really have them or have to find them.
Not sure I trust the Amazon seller(s). Sketchy info. Says not mfg discontinues.

Thanks for your suggestions!
