Which one is the colder plug?
Dude, you are killling me. Those are all the same part number plugs and the porcelin sticks out the exact same distance from the bottom of the plug. You can't see up into the plug to see how far the porcelin pertrudes, unless you cut the plug in half. In that picture they are showing how they make different heat range plugs. The blue indicates colder plug. NGKs part numbers run backwards from the other brands. The higher the number the colder the plug.

Same # heat range wise but the porcelain ends right near the top of the threads.
I don't know why I just know what I see.

How bout that! One is iridium IX and the other is lazer iridium?
Wtf that means ? I haven't the slightest.

Lee you should have done the reserch before making a ass of youself the higher the # the colder the plug. Good chart find.

Means The electrode tip was laser welded for better durability.

Yes the higher the number the colder and the lower the number the hotter.
It does not always matter what the # says on a plug.
A spark plug transfers it's heat away from the tip through porcelain to metal contact. The metal transfers the heat to the head.
If one plug has more porcelain to metal contact then it is a colder plug.
If another plug has less porcelain to metal contact then it is a hotter plug cause it takes longer for the heat to transfer to the head.
It's not rocket science , there is nothing inside the spark plug that makes it run hotter or colder .
When looking down into the plug you can see the porcelain on the CR9EIA-9 doesn't come all the way to the tip of the plug. It looks more like the one on the left.
The CR9EIX has the porcelain almost all the way to the tip.
AlsoI just heard from NGK that the ground strap on the laser plug is made of iridium , that's what makes it "laser". Never knew that before.

Laser iridium vs. Iridium ix here we go!
Laser Iridium ®
spark plugs provide superior ignitability and long service life. Smallest tip diameter available Iridium / Platinum surfaces ensure slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions
Laser welded Iridium center electrode tip Platinum disc welded to backside of ground electrode provides long life Trivalent Metal Plating for superior anti- corrosion and anti-seizing Faster starts and quicker acceleration Better fuel economy and lower emissions Best OEM Iridium spark plug available Original Equipment Manufacturer approved design

So...which one is better? I have always ran the stock Laser Iridium in the 14. I have always ran the Iridium IX plugs in my zx-11.

They are both great plugs and I cant feel any differance. The IX plug is what I have been using. Good info here and its not a colder plug than the EIA like dumbass thought before getting the facts.

So if I run a regular CR9E plug is that hotter or colder than the CR9EIX?....LMAO BTW, the CR9E can be run and seems to work fine in the bike too at half the price.

Think this is heading towards an oil rant thread.......it's down to preference vs. application - i'd say its up to how the bike is expected to perform, what it needs to do so consistantly, and most importantly how its tuned - i prefer the better performing plug with best durability.......but only for peace of mind since i dont race mine

That all depends if you know what makes a plug a hotter plug or what makes a plug a colder plug.
It's not just the number alone!
A longer porcelain insulator will make a plug hotter, a shorter porcelain insulator will make the plug colder . Why? The longer insulator takes longer for the heat to get to the head. The shorter insulator is quicker at getting the heat to the head.
Now im not saying it is a whole hell of a big change in heat range but it's big enough that engine builders and racers will use these slight i would say half heat ranges to their advantage. We on the street could barely niotice running a copper core or an iridium .
I'm not trying to be a smart ass , a know it all or what ever ,or get personal with anyone even though it may seem that way to some people . I apologize for any misconseption as this is and never will be my intention. I'm only sharing my findings.
My point is simply this.
Look at the pic . Without knowing #'s! Can you spot the plug that is hotter??
Hint : they are arranged from hotter to colder
Now if you were to stay in the same plug # like, cr9e . cr7e, cr6e , etc. then going by numbers is accurate. But say you go to the cr9eh and try to compare the insulator to the cr9e what will you find ? You will find the cr9eh is a hotter plug cause the insulator is much longer. Same goes with cr9eix and the cr9eia-9 . Stay with the same #cr9eix, cr8eix, cr7eix etc. the heat ranges will stay accurate to their #, Compare both plugs of the same heat range # and i promise you will find the porcelain insulators will be different lengths, and they are enough to be a half a heat range.

Just as long as you know that the CR9EIA-9 and the CR9EIX iridium plugs are not the same plug lol!

Oh, i get they're different - and there's several more brands and models of each brand available thats not being discussed, but its up to the owner and what they feel is neccessary for their own bike - preference vs application

Well that is completely up to you.
Pick one that suits your needs most.
A simple breakdown of both plugs is, the lasers have platinum built into the ground electrode to increase longevity. And is more expensive.
The IX is a half heat range colder of a plug and has no platinum in the ground electrode. It will wear a bit faster and costs less.

All the sparkplugs are a "#9" heat range can you believe it?
hot , warm ,cool
From left to right cr9eh , cr9eix, cr9e.
They are all a "half a heat range" different from each other.
Cr9e is a copper core and has almost no insulator when compared to the others. Would explain why some bikes with different setups , like a rich fuel map wont run right with the cr9e cause it is a little too cold of a plug and will not burn off excess fuel . But when they put the stock type back in their bikes run right even both plugs are "#9's"
