Any one here got any opinions on these plugs good or bad.

 

Cheers

Been using the GReddy Iridium plugs for the last year with no problems at all, i've been very pleased with them. I know a lot of other people use the HKS/Denso also with no problems either.

LOL here we go again Simon with a big can of worms,Ok I will start........................

 

 

I used HKS iridium super fire racing plugs and I was MORE than happy with them. :bow:

Not massively impressed with them myself. Were fine to start with but didn't last very long before causing poor running & poor starting problems. Went back to pukka Nissan (NGK) plugs and all fine again.

Andy what make did you use?

What boost you running Andy ?

Simon do a search, I personally use NGK pfr6b-11b, this subject has been chewed to death :D

Oi Mark,I was told the NGK plugs crumble at high boost but maybe he needs to take some of these.................................. :rofl:

Denso are really good in my bike :bow: never had them in the Zee yet :x: but will do next time :dance:

Andy what make did you use?

 

Think it was the ND ones (from Johnny).

Was running about 12.5 psi I think.
