more likely the engine running lean to cause them to melt....
I've had the ceramic crack on one of the Denso IK27's I have installed, I replaced the one plug and all appears to be OK.
I think if I were going to change plugs, I would buy a different brand

cracking and melting are 2 different things..
I installed a new set of Denso IK27's, then a week or so later was checking the gap on them and noticed the crack. I just replaced the cracked one with a new one and I THINK all is still OK.
I'm thinking of changing the Denso's to another type (racing 9's) though as I get a bit worried about it cracking again

the hks plugs are made by denso aswell arent they?
ive always used ngk iridiums and never had a problem with them.

one of the main reasons for plug breakdowns is the ht leads!
as the spark tracks down the outside of the plug and causes it to crack!
early ford mondeo's were notorious for this.
if you find this has happened to your plug then change that lead at the same time as theres a good chance that it will happen again;-)
the only plugs i will not buy for any vehicle due to many probs in the past are: champion! they are truly useless and a waste of money
i generally use ngk's on any vehicle i work on, but denso and bosch also are not far behind in terms of quality.
however you do occasionally get a faulty batch of plugs that do not work properly, ive had this a few times even with ngk, so just return them to wherever you bought them and get yourself another set!
