OEM Plugs are platinum as are most of the aftermarket replacements.
OP, did you clean out the threads and cylinder before putting the new plug in? Sounds like you could've had some broken porcelain in the cylinder. Unless you vacummed out the combustion chamber (Tube and shop vac) that's probably what you heard.
