NGK Irridium vs. Double platinum. I can't seem to decide which one. Even though I keep reading that irridium is better, It doesn't seem right that the better one would be half the price. Can anyone confirm Irridium is good/better/best for our car?

 

You dont need iridium if your making stock power, or bolt on Power.

Stick with the Coppers or the Double Platinum if you wish but Iridium is a waste and might decrease performance a bit.

 

Yay, I have them.
They are better then platnium as far I am concernd... But what do I know?

 

Why did you start 2 threads for this?

 

sorry, the other one was for the plats, just wanted some clarification on irridiums for this one..

 

They'll last longer and that's it

 

go with the oem irridium plugs, plat. plugs made my ignition coils die

 

Your first post ever and you're wrong

... Plats were OEM.

 

i agree, im using iridiums and i dont recommend until you are FI or NOS, i just have bolt-ons and since i got the iridiums, seems like i lost some power compared to the old platinums i had before.

 

Nay, use platinums.

 

thank you all, plats it is

 

good choice.

 

are you boosted? if not you will not notice any performance diffrence whether you use coppers iridiums or platinums. whatever you do dont use those POS bosch platinum +4...they suk my as5.

 

Irridium plugs are only for High performance applications, If your stock or NA, get copper plugs, best bang for your buck
