iridium or standard

[Tkosanic]

What its the benefit to the NGK iridium over the NGK standard? Or is there even an advantage.

[gibvel]

Longer life and less changes.

 

Goose did some experimentation with standard and iridium plugs once and there was no difference in performance or MPG with the iridium over the standard.

 

So the only advantage is that you don't have to change them as often.

I agree with Goose. I've tried the Iridiums and in fact, they are installed now. I see no advantage at all though.

My 1st set of NGK Iridium plugs were changed out when I had put 60K on them. They looked as good as the day they were installed. I for one am very happy with the performance of these plugs. Can't say if they increased my mpg or not cuz I don't waste my time with mpg stats....more fun to just enjoy the ride and get gas when needed!

Boomer....who sez the less time spent changing plugs equals more time fer riding.

I think the Iridiums are harder to foul than a standard plug also, but this is just an opinion. No basis in reality.

I have 25,000 miles on mine with no trouble as expected.

 

Thoughts on Iridiums...

- less wear of gap to extend life at proper gap

- less chance of fouling

- longer life

 

I've used Iridium plugs whenever I can on whatever vehicle I can.

OK so heres a simular question. Gap type plugs or the "gapless" fire to side or whatever. Not the standard center electrode over pin. I pulled a set of factory Iridiums out of the wifes Durango with about 110K. they were burnt up but what the hect do you expect with that many miles and 10yrs. I think anything else would have been gone long time ago.
