Platinum Vs. Iridium

[dazwan]

I finally got some new plugs for the car (Engine is 7A-FE). Most places recomend using Platinum Plugs but when I've gone to put the plugs in there is a sticker on the engine which says "only use Iridium plugs".

Is there any real difference between the two types and is it safe to use Platinum plugs.

Also, do I have to change the gap on the plugs or should I leave the gap that was on the plugs out of the box (I reckon the gap is about 1.1 but I don't have any guages that thick!).

Iridium is a hotter plug it burns white rather than platium blue it is also designed for extended periods of use excellent for turbo and supercharged applications and is a sure thing for 100 000km so you dont have to change them!!!!!

the plug is actually made for the application so no you dont have to change the gap !!!

So you are saying I should have another 30k left on the plugs in the Avensis? :P :D :P

(The original Iridium ones that is)

I have run these things for the life of my two previos motors 356 000km and swear by them

but with my new motor being turbo have found that i have had to drop a complete heat range to avoid detination being so hot
