Fiesta ST Spark plug tech

[golfhack]

I just put in the Denso ITV22. I'll let u guys know how they work for me.

that good to hear, bet your relieved to see that! Are the positive corrections your seeing more consistent now across all 4 cylinders with these cooler plugs and narrower gap?

Yeah, definitely. Now we can turn the boost up further

What socket are u using to replace these. My 5/8 won't fit

 

[golfhack]

Hmmm, I thought that was the size I used. I know it needed to be a thin walled socket. I'll take look later tonight.

 

[westcoaST]

I had to buy a thin wall, extended length socket. I got it from KD tools through Amazon. Standard 5/8 sockets are too thick and too short.

I'll be waiting too hear, these are the plugs I'll be placing in shortly.

 

[golfhack]

I was having problem with inconsistent corrections across all 4 cylinders and the Densos have seemed to cleaned that up.

Denso ITV-22????? I thought The FiST uses the ITV-20

 

[golfhack]

The 22's are a step colder

 

[fiestastdaily]

any updates on the denso ITV-22s?

 

[golfhack]

To tell u the truth, other than what I have already mentioned, nothing notable.

Does anybody have the torque specifications for the spark plugs? I know the general rule for tightening plugs, but I just like the reassurance of tightening things to there spec.

Sorry to reopen this old thread. I'm getting ready to change my plugs. Has there been any updates on the spark plug front? Has a 1-step colder plug, with the stock reach into the cylinder, plug been found?

Yessir, you can use either NGK 6510, or Denso ITV22.

 

[CanadianGuy]

Been running the Denso ITV22 for 35k km. No issues.

So no gapping these just purchase and put in ?

If you buy the "generics" they do not come pre-gapped. I would get the NGKs over the Densos. I got my NGKs from AutoZone, using the generic part number. I believe it cross references to the Cadillac ATS with the turbo 4cyl. You can either buy these pre-gapped from a vendor like Whoosh or Tune+ or Stratified, or gap them yourself. They do not come pre-gapped if you buy them as generics (e.g on Amazon or VatoZone or O'Reillys, etc).

Changed the stockers for the NGKs, Today. 76k miles, and were gapped at .032. I dont think they look bad. But, I've never quite gotten into reading plugs. The NGKs, I gapped to .026. May be placebo, but, everything feels smoother. Over 50k of those miles are Stg 1 tuned by Cobb and Stratified. Wondering if the intermittent hesitation when accelerating was caused by the stockers being gapped so wide. Time will tell...

Anyone notice it's harder to start with the NGK's ? The Denso's def effected how quickly the engine started up on my car.

 

[alexrex20]

Yes the NGKs take about .25sec longer to start the car sometimes.
