NGK or Denso

[OLD FART]

Which is the best plug for a lightly modified, stock-boost
Terminator? Also, where's the best place to buy either
of them in the Dallas area? Thanks :beer:

I've had really good luck with Denso IT20's. They are the same heat range as Motorcraft 12FM1 plugs. The 12FM1 plugs were used in some 1st run 03 Cobras. The Denso's will work for stock boost on up to 12 or 13 lbs. For stock boost, I would gap them at 0.040in.

My last dyno with the IT20's didn't show a hint of spark blowout.

ALA G8R, Thanks for the info.

I like my Densos. I had IT20s and recently switched to IT22s.

Bob,
Why did you change to 22's?

I'm about to fit a 2.8 and have a set of IT20's sitting ready to go (planning the Apten or LFP Eaton later this year).

However I just ordered a set of AGSF12-FM1 as I've heard so many bad things about the Denso's cracking and breaking.

That is what I heard as well with the Denso.. lots of them cracking and dropping the pocelin into the cylider, that could be really bad if a valve crushes it on the way out the exaust.

I am about to put on a 2.8, which plug would be better, it22 or it20's?
