iridium plugs on 2006 nissan

As in will you see a performance improvement? No, the factory platnums are good plugs.

No. There is NO performance in the spark plug, unless they are the wrong heat range or they are TOTALLY worn out. Lots of hype about this but no substance.

Why?

You ever heard the mechanic's motto

If it ain't broke, don't fix it.

According to NGK, Iridium allows for the electrode to be thinner and the spark becomes stronger, burning the fuel mixture better. Iridiums are way cheaper than platinums, but the platinums are good enough.

I guess you would > anyone changed to iridium plugs on the new 2006 nissan models? worth doing?

Hi Guys

The most important thing to remember when it comes to Spark Plugs. If you are using Copper, Platinum or Iridium plugs, the most important thing is to make sure the plugs are NOT worn out. Platinum and Iridium plugs will last the longest, Copper the least.

Basically, you can have brand new Copper plugs and they will out perform worn out Iiridum or Platinum plugs.
