so what about the iridiums?

 

basically they are just as good as copper, but can last longer. some people say the notice power with them, but that is usually from people who have platinums. i have yet to see a ngk copper user switch to iridiums and say they felt a gain in power.

another thing is people often mistake power gain from simply replacing old plugs with new ones. sometimes you also get the placebo effect also. which is when one thinks that since they spent $$$ on something makes them feel like they noticed a power gain.

 

Thanks for posting it Sleeper, so I don't have to...

 

whatt the hell are you talking about??? that's exactly what i said -- platinums last longer, not copper!! what the hell kinda newbie do you take me for??

but yeah, what you said is true.

btw, my friend, which is a "real racer" in your terms, has copper plugs in his car and he has always changed it at 2000 miles. he drove it to 3500 one time and then bang, engine rebuild #2. maybe it's because it's an FI car.

 

thanks... now i guess you saved me 50 bucks... thanks!
