Stock Plugs.

Race cars have the plugs all of the time, a normal street car works the best with stock plugs. Not even a comparison worth making.

I wasnt making a comparo
All I was pointing out was NGK OR AUTOLITE COPPERS ARE NOT JUNK....

Its all good, The stock plugs are fine for MOST setups..

guys the reason for iridium is kinda complex, but makes a lot of sense for higher CR and high boost engines.

Take for example copper. Easily found, and one of the best conductors. Only other noteable one with a large difference is silver.

Normally, for the amount of metal on a spark plug, and the resistance difference between iridium, platinum, and copper, you wouldn't notice a difference, if it was like a wall outlet or ran off of 12V. but these things are ran off of 50K volts(probably more!).

so a .00001 difference in resistance, means a decent amperage loss in the form of heat.

Also consider the temperature range(not how hot the plug can stand, but of the metals). Now i am not sure of specifics, but i KNOW iridium is higher then copper. It survives entry into earth without being vaporized into a plasma!(fyi iridium is not found naturally on this earth in mineable quantities)

/end science lesson

I went down from iridium to those platinum plugs one time in my old car. Big mistake. It even idled rough, with brand new plugs!

i definitely agree with stock, or a slight difference in heat range due to conditions...

I don't see where anyone said they were JUNK,

What was said is, they don't work as well in a 2010 Camaro as the stock plugs do.

Everything has it's Place and or application.

We are running stock plugs in our 740+ RWHP LS3 with fantastic results.

Gotcha pal

AZ5G · 08-12-2010, 10:57 PM

Hmmmm...At 10k, changed to the NGK TR55IX with Granatelli wires and gained 9 RWHP...Bonus....It idles much better. Gapped plugs to .050....DD....Almost forgot to mention the stock plugs had no anti-sieze on them and were already showing signs of corrosion at the base, in AZ, car's never seen rain....DD
