Spark plug caps

[new maxer]

Can anybody tell me the best spark plug caps to use. I'm thinking NGK, does anyone know what their part # is

[mark the shark]

Yamaha part number for the plug cap assembly is 81E-82370-20-00
You should be able to cross reference from that number. I Googled it and got about 5,000 results.
I would think that NGK or MSD ignition would be good choices.

I finally got new spark plug caps. NGK part # LB05EZ. Picked them up for $2.00 each, sure beats the $20 that Yamaha wanted for them. I've always had good luck in the past with NGK
