Spark Plug "tip"

When changing spark plugs, always use Motorcraft double platinum's, or fine wire platinum's. They are designed to be
the correct heat range for your 2.3L, 3.0L, or 4.0L engine, as well as Ford's EDIS.

A word of caution about gapping these plugs. On the double platinum's, there are platinum beads on the center electrode, as well as the outer electrode:










Make sure you use the "wire" type of spark plug gauge, NOT the "circular" type of gauge.
When using the "wire" type of gauge, DO NOT use force to insert it in the gap, the platinum
beads can be easily damaged. To adjust the gap, bend the outer electrode close to the
spark plug threads.


Use one of these type of gap gauges:

DO NOT use this type of gap gauge:

OK. I'll use a platinum plug.. and when half of it freezes, falls off and makes it between the cylinder wall and piston, taking out the rings.. will you buy me a new engine?

I'll stick with my coppers.

That's been known to happen with Bosch platinums, NOT Motorcraft, Autolite, or NGKs.

Why are the circular ones bad?

probably not as accurate seeing as it looks like a slow increase in thickness not set, flat thicknesses

Again, You fail. Hint on the word ' freezes '. You just don't get it and never will. Your Motorcraft, Autolites and NGK's will do the same.

It's ok D. Some types of plugs are just not well suited to power adders.

technically you're not suppost to adjust the gap on platinum plugs cause it will damage the tip.

I'm sorry D, as with many things, your wrong again! The platinum has come loose only on Bosch plugs from thermal shock, and even mechanical shock from pre-ignition!

We both know that. Mr. ' Ayers ' didn't catch on though.

X73298784290. Funny how he goes to Sema and has aftermarket parts on his truck yet he hates aftermarket parts.

IMO for a **stock** motor that will see **stock** conditions. Bob is right.

But for a power adder like a turbo, blower, or nitrous. I choose to ignore his advise. In that realm he knows not what he speaks of.
I'll take high quality materials and a unshrouded spark thank you.

Rich, the purpose of this thread was to understand the proper way to gap platinum plugs!


Do you want to start discussing what you don't know? I wouldn't trust anything from somebody that chooses to run the wrong heat range plug most of the time.......

Just incase you haven't noticed, the Densos you are running have the same electrode structure as Motorcrafts (shrouded). I'm not surprised you fell for the "unshrouded"
marketing hype BS!!!! As far as platinum, and iridium, these metals are used on electrodes to make the plugs longer life by reducing erosion.

I gotta say, Bob is right, this is the proper way to gap a platinum plug. Most platinums come pre-gapped, but if you ever find yourself in need of gapping a platinum, this is the proper procedure to follow.

You know Bob.. when your a hammer everything starts to look like a nail. The days of me trying to reason with you based on science and logic are over.

Nice quality pictures and a good post. Thank you for the info.

Rich, over and over you have shown a lack of understanding when it comes to basic electrical principles (MAF sensor operation, spark plug heat range,
falling for "buzz" words like "unshrouded", proper battery voltage, capacitor operation, etc.).
For somebody with an engineering degree, I find this surprising.

But, I have to hand it to you, at least you admit to it:


"I could have my EE friend measure something and tell you what you need to know? (I'm ignorant about this stuff)"
