NGK TR55 spark plugs good for LT1 ?

[Kevin - Blown 95 TA]

I don't know what to tell you Steve. Do you know that iridium came to Earth on an asteroid?

TR55 - standard plug
TR55GP - single platinum
TR55IX - single iridium

The above plugs have a standard ground electrode subject to wear

PTR4B-15 - double platinum
ITR4A15 - iridium center electrode & platinum puck ground

THESE are the 100,000 mile plugs

The iridium/platinum retails for about $10
