My NC30 has iridium plugs in it (ER9EH-IX)

With the ZXR400 the general concensus was that the standard plugs were better in the bike.

The bike starts easy and runs great, the idles a little wishy but will be servicing the carbs, balancing and replacing the rubbers at the weekend.

Does anyone else run the iridum plugs and have they found they run ok in the bike?

nout wrong with normal plugs tbh, iradium are just over priced and do the same thing a normal one does . i use them in my 2t but often find myself swopping back to standards coz once they foul the wont fire.

Never used them and don't personally subscribe to the hype.

I never use them either.
I do prefer Nippon Denso plugs to ngk's in my nc though

The main advantage of using Iridium or Platinum plugs is service life.

They are good for modern vehicles with plugs that are extrememly difficult to get to, and can take hours to change, so less frequent changes are a big plus.

I don't use them.

I've had 35k km's out of a 1 set of standard plugs before. Don't know that you would want much more mileage than this!

Nothing more than marketing and money grabbing if you ask me...

on a similar note, why is it that the tiny vfr plugs are so fking dear!? my singlr cylinder cagive runs on 1 bigger plug which only costs about 4 quid. to replace all 4 of mine im looking at 40 quid!?

40 quid?!??!!

Bargain!

lol, how? why? more than a tenner a plug?? there about half the size of my other ones.lol

Because they are 8mm (tiny!) and there are only 3 models of bikes that use them.

New tooling to manufacture them plus less volume equals higher cost!

If you think the ER9/10's are dear then try the ngk 8mm race plugs.

Sorry for getting off topic...
