Just replaced plugs on my 94 pick up w\ 22re engine. As always have done in the past I purchased the plugs from my trusty Toyota dealer. Had done this previously in 2002 but this time after I removed the old plugs realized that the new plugs were different. Checked the depth\etc of the new plug & it matched, so went ahead & installed the new ones & fired up the truck & it ran just fine. Just assumed that they had changed the plug to a newer design. Couple days later was passing by the dealer & drove in & found the same parts guy & asked him when they changed to the new plug & design & he says they hadn't!!! Turns out he had the platinum(iridium) plugs in the wrong slot & had picked them up by mistake. My question now is should I remove the platinums & replace them w\ the correct plug, which by the way, they gave me @ no charge or just leave them alone. Truck is running fine w\ the platinums installed but service manager said he would be afraid that over a long period of time may do some damage cause they are a "hotter" plug than the conventional ones. Advice needed from those of you that know how this may affect my engine would be appreciated. Thanks dc
