I guarantee it will require more force for removal than the recommended install torque settings

The ST Helm manual calls for 13nm. I just guessed as my torque wrench doesn't go down that far.

Yes they are iridium. Anti seize for sure. If you stayed at a Holiday Inn you're good to go. I use feeler gauges to the desired gap. Hold the plug in a vise gentle tap it doesn't take much force. Old plug lefty loosey new plug righty tighty. NGK come .044 I put mine at .028

.044 that seems very high. When you gapped them does the top arm kinda sag down now? Is that ok?

Nope that is too far of a gap down and I believe ngk recommends gap no more than .010 down from original gap.

I'm running ungapped, no problems. Logs look good.

Which plugs are you using? NGK? At .044 out of the box?! (Head explodes)

 

[KristianST]

I'm worried about using a couple of these, does this picture tell you anything?

You bendee spark plug electrode?

Yeah. Out of the box, didn't check the gap other than visually.. Couldn't find my gapper. Lol

Nope out of the box some looked really awkward

Out of four denso's itv22 that I got from Edge, one had center electrode bent like yours out of the box....Gapped them at 0.28" and had random misfire around 5200 rpm twice in an hour driving enthusiastically..Took them out and carefully re-gaped them at 0.26".. Big difference, before I would get dead range in my gas pedal while slowly rolling into boost almost like fuel mapping issue....not anymore, strong, even and linear spool all the way up to 6000rpm. Running mr. T's 93 V5 aggro, forge IC,K&N filter.....After installing Denso's didn't do reflash, didn't reset KAM or change anything other than spark plugs...my old plugs( orig. fomoco ) looked good after 32k, nicely tan brownish colored...

So you through it in even with a center electro bent?

 

[DB1E]

Yes I've put them in with one of them having slightly bent electrode, just like yours....hmmm makes me think if any other forum members got one spark plug tip bent in a set of four as it appears we have pattern forming....

Ok, NGK's out of the box misfire under certain conditions running V5A 25psi but not the regular 93 tune. Spark probably blowing out.
I'll be shortening the gap tomorrow.
Only happens under full load and full boost. Seems like just one cylinder also.

25 psi? I bet you need a tight gap to overcome the effect of high pressure.

It's technically 24.xxxx but yeah I'm not even going to bother logging to try to reproduce the miss. Gonna go with .32 and if I need to drop it to .28 I will. If I still get a miss, switching to Denso's.

It's been a few weeks and I haven't had any problems with NGKs gapped at .028. I've updated my Cobb firmware, sent Randy some data logs, and got a new tune. Going to try some data logging this weekend but it looks like rain. 10min of rain in Phoenix equals flood.

Mine is set to 0.028" and no problems thus far. 5000kms. Started my eth tune too, Plugs are holding nicely.

So you guys are suggesting go straight for. 028. Going to do it right now. Just thought that was too far from the original NGK design.

I guess I should also let my tuner know what I'm up to.

****** loco is right that to put the gap in ford spec range is more than NGK suggest for gapping their plugs. I felt comfortable going the extra .006" to put it at .028". .030 is within Ford's spec and only .004" out of NGK's. I probably should have started there to collect data but I didn't.

If this helps here's a pic right after a series of pulls. No noticible deformation of the ground electrode from going out of NGK gapping specs. Yup, that's anti seize... I'm a rebel
