According to Denso, the ITV22 is a step colder than the stock LTR6 plugs

LTR6 = ITV20
LTR7 = ITV22

Thanks for the pic info, but we already knew that and that is what we are trying to figure out. Is why people are pulling a ngk plug that is 1 step hotter and differant brand then what the Ford parts system is saying should be in our car (oem spec).

The part number for the MS3 factory plug is ILTR6A-8G. Again with the 6 indicating heat range and why they run ITV22/LTR7's as one step colder. Anybody with a 2014 want to pull out a spark plug and see what it says?

 

[go46ball]

has anyone pulled an LTR7 out of a car yet? I have a feeling ford just has is F@#*ed up in the parts system.....

seems like LTR6 is the correct plug since that is what is in all of our cars from the factory... making ITV22 be a step colder...

But then why would Ford Racing offer a 2 step colder plug for a calibration tune (way overkill and plugs would foul out quick causing misfires), that is why I am thinking if anything Ford made a change and as long as there are no issues brought up then they aren't pulling the NGK's to replace them with the new plug reference. But if you were to take your car in for a tune up today, I bet if you pulled the plug it would be a SP-527 plug.

I would question the spark plug cross reference site before I question ford. It is possible that they could have it wrong or that the ITV22 only pulls up because that is the only plug they have in the system that fits the same as the SP-527. That still leaves the question as to why ford racing offers the ITV24 as an upgrade with their tune.

EDIT:

Just saw this in the Ford Racing Tune thread in the OP.

This tune has been tested thoroughly by Ford Racing. Its going to boost your power within safe parameters (tapping into what Ford left on the table) ensuring that you aren't generating engine temps that might contribute to failure of the catalytic converter.

I could be wrong here but I think what might be going on with the ITV24's is ford is running 2 step colder plugs to keep the engine temps down for fear damaging or fouling out the factory catalytic converter.

maybe the guy making the SEMA display board put 24's on it cause all the 22's they had were in test cars, LOL.. we are putting alot of faith in a display that may not even be exactly whats included in the upgrade.

 

[go46ball]

I would have to agree!

from all this data I think that the 22 is a step colder.

I will send you back the 24's when they get here next week and swap them out. Thanks EDGE.

That is actually a very good point!! Denso ITV22's have been on a galactic back order for over a year now with a few sets trickling in here and there. We have a handful of sets in stock right now from a small surprise shipment we got a couple weeks ago (our first in over 6 months and no where near the amount we have on order). But most places don't have them because they are very hard to come by at this time. So it actually could be pretty reasonable to assume that they just stuck some ITV24's up there to complete the display and hoped no one would notice.

I like this thread. When we figure out which plugs to go with, I will order some.

I can't wait to follow this build... Do you have a build thread where you are detailing everything?

The ST owners guide supplement calls for the CFYS12Y2 spark plug, which cross references to an Autolite XP5363, and on the autolite cross reference is also the Motorcraft SP-527 as specified in the Ford part's system as being the o.e. replacement heat range for the ST which is by all accounts one range colder than you're seeming to find in your engines when you have pulled them.

Why would the manual specify something that isn't actually on the car? (Like the twin plate clutch, and other misnomers in the guide).

No tr3 performance is gonna create one soon tho. I have posted pics of my build on the vendors section on tr3... Check it out and reply if u want or pm.. I honestly cant wait and ik i mention it alot but im only 23 yrs old and im anxious bout it.. I want the best and i want it done right

 

[UnfocusedST]

So I'm wondering if they put the wrong plugs in our cars because of a shortage?

I doubt the wrong plugs are in the cars... Its more likely that the Autolite and Motocraft plugs are not one step colder and than stock.

 

[luckypants]

Could it be that the "old" plugs are euro spec that got installed in all our motors since they were built in Valencia for a while until Ford spec'd different ones for the US?

 

[gringoloco]

I am going to try out the ITV24 plugs, just going with my gut on this one. Worse case scenario they are too cold and foul out, Edge if we really have the stock heat range of the plugs you pulled then it's another misguided information from the manual, etc. But I wonder if ATP, TR3, Kmac have even changed to different plugs? No posts about eating plugs, so if we all have the ngk's then there hasn't been any issues running them so far up to the fuel limit of the stock setup. So I don't think we can go wrong with either the ITV22 (or ngk equal) or the ITV24. The only thing I don't like about the ngk's is they are gapped to .44 the ITV22-24 are gapped to .30-.32 almost factory spec. To gap down the ngk's to .30 is a lot and irridiums aren't really made to gap so to speak, or if you do you have to be really careful. Because the tip is very fragile since there isn't much material there.

 

[Yellowjacket]

Keep in mind that Ford will install whatever plug will achive the lowest emissions possible. In this case I would suspect the hottest plug it can handle with the most efficient burn. Im out of town at the moment and have no way of finding out. Being the plugs are iridium, I dont think even 2 steps colder would foul. Just my opinion. I did order a set of the denso 24's and will run them during my tuning session.

Just asking, has anyone fouled a modern iridium or platinum plug? Its been my experience that they are pretty resistant to loading up. The newer ignition systems are pretty stout.

Thanks skizzo81, we'll look forward to some of the results from your thread.
