I want to change my spark plug maybe with an iridium set but I’ve a couple of questions..

Worth it to go with the iridium?

With the iridium I must increase the spark gap?
I’ve read that the correct original spark gap for the 400L is 0.7-0.8 (right?)



Thanks to all.

i have read lots of posts about iriduim spark plugs and it seems that people have had problems with them or make no noticable difference.
personally i would just stick with ngk's
have a quick search and you'll find a few topics on them already

Mmm..ok that's what I suspected..

I' think I'll go with the standard spark plug..

i have also heard over the years iridiums are a waste of time on a zxr400 they don't like em, stick with the originals.
