Am I understanding spark plugs right?

[JDCMoney]

I just read alot of info esp from reptile there...

last week I did a complete tune up including a/c delco wires and iridium plugs.

but from what I understand now I should put in autolite 104s gapped .050-.055 with my setup

I have a thrasher CAI, 3.4" Pulley, 160* Thermostat, ported and polished blower, cat/ubend/res delete.

With that do you guys recommend changing the iridiums with autolite 104s gapped at .052?

yes, i would. i put iridiums on mine a while back and i got nothin but misfires. stick with the copper al 104's.

Is your car missing? Is it knocking? If not leave them.

the iridiums will last longer, but the coppers will make the car run better just because of how they work.

First I would open up that exhaust to breath properly and scan for knock because the only exhaust mod I can see is a cat/res/u bend delete? But coppers are better but will wear faster.
