Ngk iridium part number

[YoNkErS87t]

Does anybody have the part number for the ngk iridium plugs?

I would rather have the ngk's because the denso's cost like $90 bucks for all six.

Why pray tell are you using "Iridium" for a turbo application???

I'm aware of mkiiitech section on plugs and the debate:
copper are just fine, cheaper, change more often, iridium are stronger, last longer, waste of money
Your question makes it sound like iridium should not be used on a turbo.

...These plug types are usually recommended for high power turbo charged engines where wear may otherwise be accelerated...

NGK Iridium plugs are exceptional for use in nitrous fueled, fuel injection and turbo charged engines.
sale hype I'm sure.
But could you explain your question?
fyi me, thanks.

[figgie]

simple...and mkiiitech explains it well.

The POINT (yes it is a point not a cylinder like in copper plugs) in Iridium spark plugs will NOT dispatte heat well. Meaning at elevated boosted levels. The chance of auto ignition is high.

[isnms]

ok, then my question now is: what boost levels are you referring to?
oem is platinum not copper

I am waiting for my ngks iridiums to come, maybe autolites are ok for you guys but my car runs like shit with them.

These spark plugs are copper core. I supply these to all the top racers in the Summit Sport Compact Series. They run 50 lbs boost and around 1500 hp. If they can use this, you can no problem.

I reciently bought and installed 1 heat range colder iridiums in my car with the NGK plug wires. Runs smooth as butter for me.
