For a while on my new motor i've been running NGK BKR7E sparkplugs. Car idled and ran good...
I blew my headgasket with only 900 miles on my new motor. Replaced it today, and put in my NGK BKR8EIX sparkplugs. The plugs are 1 stage colder then what i was previously running, but they are Iridium.
The iridium plugs actually do run SMOOTHER then copper plugs. The car idles smoother, cruises smoother, and when i pulled the plugs they looked very clean for just cruising with such a cold plug. After all they are 3 stages colder then stock...
So, all in all, i feel that the Iridium sparkplugs actually do fire easier then a standard copper plug, which i didnt believe until i ran them...

or, its all in your head...

Copper here, replace every other oil charged

which plugs does the great mase use on boosted hondas?

How about non boosted ones?

I thought the whole point of the coppers was the fatter electrode and that the iridiums were way more prone to detenation because of the tiny electrode.

I must have missed the part with the measured results from a definative testing process...

I will stick with my copper core ngk's...

Seeing as how copper is a better conductor than Iridium/platinum, I don't understand how it could be a 'better' plug.

non-VTEC

the only thing platinum and iridium plugs are good for is longevity......they will not wear out nearly as fast as normal copper plugs.

It's not worth the extra cash.

No ****! LoL...

It's all in your head man. The only thing better about the iridium plugs is the weight savings from having a lightened wallet after buying them.

from what i read, they say iridium is easier for the spark to jump the gap with less voltage...then copper...
I hate platinum, they suck, and misfire like crazy....

I dont know guys, i was just saying what i feel. I have always ran copper plugs in my cars and nothing else, but after talking to a few people with supras, they run these plugs and love them, so i gave them a shot and my car does idle smoother. I have no-vtec with a large camshaft....so i have a lopey idle.... I feel its smoother idling and in the lower r's cruisin with the BKR8EIX...
