V10 iridium spark plugs

[mikgnumv10]

Has anybody used iridium spark plugs in their v10 magnum? Is there any difference? I saw some champion iridium and NGK iridium plugs for $6 each on rockauto.

From what I understand, those plugs are too hot for the heat range and can actually downgrade performance and MPG.

That's not how it works.


No dont bother with iridium. They have a higher resistance to current and being these trucks came with copper, stick to copper. The ignition on these isn't outrageously strong
