You may not know it, but my job is parts.
NGK is one of my vendors. I am a NAPA sales manager.
I'll make a few calls.
I still need verification. Are the plugs you seek copper or platinum or iridium?
I also own a performance shop. I wonder.... why you are damaging plugs? I race IHRA with supercharged and nitrous engines. Properly tuned, they do not eat spark plugs at all. I build a lot of race cars, from big-block domestic iron to import aluminum.
