I was looking to replace my plugs... online the Iridiums are cheaper than the 2x Platinum plugs, but I thought the Iridiums were better/more premium/higher quality than the 2x platinums?

Which one is considered the higher-end plug?

Any "downside" to the Iridium plug?

TIA

Well what was ur reasoning for going with those plugs ? Because performance wise i have heard coppers are better (NGK v-power). From what I understand the only real advantage is a longer change interval. But to answer your question Im pretty sure the iridiums are higher end.

Well, from what I understand, the Platinums are the OEM replacement...???

So I checked NGK's site, and saw that the Plats were more expensive than the "higher end" iridiums. ... so I thought to myself, what the heck! might as well get the better plug for less money.

Why are the copper plugs better, performance wise? I understand where you are comming from saying that the plats/iridiums are just for longer service intervals.

I was always told and have seen on here before that coppers burn hotter and was told that like race cars run copper.

I always thought the NGK v-powers were oem replacement ? And thats what was in mine when I got it too.

The platinums are OEM and last the longest.

Yes it has been said that the coppers perform the best, are you gonna notice it? Meh... i doubt it.

When i first got my Prelude i searched and found the same questions asked, the Iridiums were by far the popular choice, they last longer then the coppers and were cheaper then the platinums.

NGK makes 2 iridium plugs. One is around $5 and the other is around $11.

One has a thicker core than the other. Not sure what a difference this makes. Look at sparkplugs.com

why not run regular copper plugs

I agree, run either the copper or regular iridium. There both cheap.

I allways thought that platinum plugs burned hotter. I would just stick with the iridiums or coppers.

I have a 92 JDM H22. It had Denso Iridium. I switched to the NGK iridium.Now my H22 kicks butt. Ask Sleepy H22, he knows. Oh thats the lower priced ones. #6441 on the NGK box. I was not aware of any thing more expensive except for the OE platinums. They are about 10.00 each.
