It really is very simple and there is very little risk of damage if you are careful.

Get a set of feeler gauges.

Select the combination that give you something between 0.026 to 0.028"

Measure to see how far the gap is currently by sliding the feeler gauges you selected between the ground strap and electrode.

If the gap needs to be closed take the plug in your hand and gently tap the ground strap against a hard surface such as a vise or concrete. After a few taps remeasure the gap until it is in range.

No special tools needed, just be gentle with it. This is safer that using something to apply pressure and bend the ground strap. The feeler gauges will not be abrasive against the iridium tip electrode either. Gapped many many plugs this way without any issues or failures.

 

I pulled my stockers. Have 26k on them. Gap on 3 plugs is .032 and 1 is .034. Coloration looked decent. Nothing out of the ordinary. Not sure if larger than suggested gap was wear or just came from factory that way. The workshop manual suggests .028-.031
I installed Brisk Plugs and gapped them to .029. Did a couple of pulls and some regular driving. Sent my datalogs off for inspection, but looks good to me (doesnt mean much). -1 was max pulled by KS. Not sure if plugs have anything to do with that, but made me feel good. Pulls were done 2nd-4th WOT.
Engine Mods are:

-Unleashed 93 V5A
-Unleashed 3" Downpipe (Catless).
-2.5" Exhaust w/ 1 resonator.
-Cobb Turbo Inlet Tube/Cobb Filter.

You are not going to get detonation from hot plugs so you won't find additional or less knock based on the plug choice in a log. If the gap is too large or they are worn out you will get misfires which you will feel as the car not accelerating smoothly while WOT in gear.

Colder plugs are a precaution against pre-ignition. If you go too far and get plugs that are too cold, then you will again have misfires, poor starting, and poorer combustion.

 

Can you post your logs on here?

 

Nice, thanks for the explanation Alex.
I am a little apprehensive about posting datalogs. Would there be any "proprietary" information accessible in data logs? I am just asking for out of respect of the tuner.

 

In the previous platform where I was heavily involved (And where the COBB AP was primarily used) logs were never seen as a violation of proprietary information and people posted them a lot especially when troubleshooting. Posting maps is obviously a different story but the logs themselves don't hold enough information to make piracy of a map possible. This is another reason why maps are locked from most vendors.

Not sure what format you used but I can't open it

 

Its just a zip file. CSV files within. Should download to your computer then right click "extract files" once downloaded.
I'll throw it into my google in a few and post a link.

Just threw in one step colder NGK plugs at .030"
I don't have Microsoft anything on my computer to look at graphs or anything. All I can do is pull the plugs and check em, and keep an eye on my accessport for misfires.

Edit .039" ...

 

It is interesting that frpp is going two heat ranges colder than the factory plug for there power kit.

So i guess the pic at sema of those denso itv24 plugs was legit.

 

I can't read logs. Don't have the ability.
I'll have to fix/gap them tomorrow

 

You don't need to watch logs for spark blowout/misfires. You'll feel the car hesitate during acceleration and perhaps hear popping from the exhaust. You will feel it right away.

 

When under full load and boost it's a very noticeable kick.. Was worried it was preignition but unlikely.

I don't think I've ever felt preignition on any car. But this misfire felt bad on this car since normally it's so smooth.

I've been reading the big turbo MS3 guys running the NGKs like yourself with no problems. Some have actually said the NGKs do better in preventing spark blowout compared to the Denso, so I'll be installing the NGKs shortly. Thanks!!!

 

Just installed ngk's with my cobb tbe. I gapped them to .28 with no problems. Seems to be pulling less timing up top then before which is what I wanted.

 

^ do you have any before and after logs?

 

No just a visual observation of the gauges.

 

has anyone figured out exactly what plugs are included in the Ford racing package?

 

Yeah it is the ITV24's. Just keep in mind that the ford tune is more aggressive but still uses the stock intercooler so the 2 step colder plugs are necessary with that package.

 

Unless something changed it should be the Denso ITV24 plugs.

 

alright, was just curious now that they have shown up, i've seen some sets on ebay but none of em show the number good enough to see

 

Has anyone used or found the Brisks preferable to the NGK or Denso's?? It would be nice to get a good summary all in one post about the options and benefits vs cost for each brand.

 

There is a lot of personal preference involved with spark plugs. Everyone has their own opinion based on personal experience. The denso's are $3 more per pack than the NGK's and are closer to the factory gap. I personally prefer NGK's due to a bad experience I had with denso's once. But I know a few guys who have had issues with the NGK's so it brings it back to personal preference. If you were to put NGK's in a car and dyno then swap out the plugs for denso's and dyno again, there would be no difference in power and torque.

 

I will be changing my plugs again tomorrow. new youtube video will be out on sunday!!!

 

Newest video, very happy with results so far!!!

 

for those of you who missed the first episode...

 

Working on a map with ignition advance for Ethanol. I changed to the NGK-11 plugs today and took a log. Here's a comparison for the same map between stock plugs and NGK. Spark would have been even higher in the upper RPM but I'm hitting a ceiling that I need to change. I gapped at .028". Big difference in corrections.

Stock plugs
NGK Plugs

 

Same ignition setting? Same calibration, different plugs only?

 

Wow. That difference is huge.

Gives me hope for my change to Denso's.
