Irridium Plugs???

The only other plug I have ever liked is the DENSO Hot "U"
W24ES-U But not the platinum -ZU.

Regarding this claim:

Silver is the best electrical and thermal conductor of any metal. This makes Nology Silverâ„¢ the best spark plugs in the world. Period!

I always thought gold was, maybe not? EDIT: I guess silver is a shade better conductivity than gold, but we always gold plated every connector we cared about because gold would stay bright for so long.

I'm always looking for inexpensive performance upgrades. Too bad they don't exist :laugh:

I think I just need new coils...

If I put my color tune plug in my #1 cylinder, the spark visibly weakens and turns yellow quickly, then goes out completely killing both cyl 1&4. If I punch it, the spark comes back, but only for a moment.

Bike runs OK, but It does miss once in a while durning take off...

New coils... for sure.

Gold is used because it will not corrode and has no electrolytic reaction with surrounding metals. Obviously here gold would not be very practical for a couple of reasons. 1) Cost, 2) melting temperature, 3) Rockwell hardness, otherwise, it would not last very long. The Nology plugs are expensive enough at $9 each. I stocked up on them about three years ago at $6 each.
