Iridium plug gap question
 

So, I am trying to be a carguy (Vash, you bastard, you inspired me again:D) and decided to change my plugs, clean the MFI and throttle body on my 5 gen 4 runner. It has close to 90,000 on it. After a few hoses and some swearing out of the way, I discovered that my original plugs are different from the number they gave me at the parts house. According the Denso catalogue on line, the plugs are correct from the parts store. I looked it up and the gap difference is 1mm vs 1.1mm. I know there's no gaping it on my own with these iridium plugs. What do you think, those of you that has experience with "modern" vehicles:D? I am temped to just put em' on. Ones I got has the larger gap, .1mm:rolleyes:

Waste of money.....use the Bosch copper or NGK.

I figure that I use stock parts?

I wouldn't sweat it, install them as is. If you try to gap the iridium plugs you'll ruin them.

For an air cooled 911 - yes. For a modern vehicle - no.
+1 to NOT changing the gap on Iridium.

Oh no, I wouldn't even try. Its twin plugged in my 930, the others, I have not looked. No can't do without a lift

Thanks. That was what I was thinking too.

Gaps never get smaller over time.

Unless something is banging against the electrode and shouldn't be. :eek:

.1mm or .004" would not worry about it, the ignition system can probably arc across 6mm gap.
