I had a misfire on the explorer, and it turned out to be a cracked plug. I have Motorcraft Finewires in there now, they aren't too old, maybe 20K? I went to the Advance site, your head could spin from the choices. I'm thinking about replacing all of them if I can get more performance.

There are also some expensive ones, one caught my eye is the denso iridium TT.



Seems to have a double finewire, which would seem to be a good choice since OEM is finewire. These plugs cross to many GM engines as well.

I don't care about longevity, but a few more ponies or mpg would be nice smile

I've been using either Denso or NGK Iridium in my Honda's since 2001. Never an issue over 100k runs.

You will gain absolutely zero power from more exotic spark plugs, generally the advantage is simply longer life.

I have always used NGK Iridiums in all my domestic vehicles and Denso in the Asian cars I have driven. (Just because of availability) and never had an issue so I stick with them. I get the rated miles and more out of them too!

I have the Denso Iridium TT spark plugs in my 03 CRV. I have about 30,000 miles on them without any problems. The one thing I noticed when I changed my old plugs out is that my idle is now rock solid. My mpg has not changed and power is about the same as before.

Those plugs look like they deliver a perfect spark.

The Denso TT is supposed to be a very good plug. And the price is so good, too smile

Here is the Denso TT site with a description and a video

Those are pretty bold claims though. I'm sure they are great plugs but will I dyno more HP?

I went with autolite platinum XP which is OEM equivalent for my application.

With modern coil on plug ignition any plug with appropriate gap and heat range is going to do the job. I personally run single electrode plugs. I feel that the x2 and x4 plugs are simply marketing
