End Plugs

[Locozodiac]

Summer is next block, been installing lately several Yam and Toh engines, both brands give customers spare new plug sets wrapped in sealed plastic bags. Have noticed both brands as delivering blackish like end colour plugs, instead as store's shelf shinny new. Well, as I like to have everything shinny, end up cleanning them with a soft paper metal sheet untill ends are as NGK factory delivered, so to stop the process of errasing my finger prints too while polishing, was wondering if using blackish plug ends compared to shinny new would be that much of a big electrical performance difference on the engine, what are your thoughts, ideas, imputs about ?

I doubt it'd make much difference given the resistances that some HT leads have.

I noticed that on the new NGK plugs . It looks like they are putting some sort of coating on them , maybe to stop corrosion or improve contact

I'd agree with Nos. Given the resistance of the air gap, a bit more from some kind of coating isn't going to make any difference at all.
