Thanks.

Those plugs are meant for AMERICAN vehicles.
Champions in Toyotas rank right up there with BOSCH
I have had bad experiences with both of those types of plugs in a TOYOTA.
Toyota has a patent on their SPARKPLUG heat ranges, so other plugs are only going to be close.
Over the last 23 years I have noted that the NGK or DENSO plugs are the only way to go. NONE of the others outlast or outperform the FACTORY PLUG.They sometimes cost the same or LESS than those aftermarket plugs.
TOYOTA has an option for a PLATINUM DENSO plug for your 95 T-100. If it were me, I would opt for them if your after a platinum plug.
Just my opinion.

Thanks, the problem is I don't see a NGK or Denso that is Double Platinum.

Did some digging and finally found the receipt. They were NGK Laser Platinum plugs. Part # BKR5EKPB-11 . The picture I found of them online showed them as a double platinum/double ground... I will pull a plug when I get a chance to see if they really were double ground as I don't remember that.

I also went to the NGK site and looked at all 5 plugs they say work on the T100. Only two of them are double ground:

NGK BKR5EKB-11 (OEM) Link
NGK BKR5EKPB-11 (Laser Platinum) Link

Don't worry about pulling your plugs, I'm going to order the "Laser Platinum" ones now and I'll see they are indeed double ground.

Thanks
