Okay, maybe I am alone on this or just used to old school stuff. Why do the plugs on this truck come without the metal ring gaskets?

Tapered seal?

 

[thePUNISHER]

Yes. Tapered seat requires no seal

That is why they need to be torqued properly, they don't have that forgiving gasket.

Hmmm guess Ill go buy a Torque wrench. I just snugged them up with one hand.

Just curious. Where are y'all buying the SP-534's from? I've called every auto shop and they don't even carry them. I had to special order them from the dealership and they won't be here till tomorrow.

Kinda sucks I won't get to throw on the tune until I've got em in.

Damn we don't have a tasco or an oreillys around here. I called both advance auto and autozone and neither of them even carry sp-534 plugs.

Some vehicles still use the "Crush rings" on the spark plugs ( usually import) But the vast majority use a tapered seat plug
Heck....my 83 Mustang GT uses tapered seat plugs...you'd prob have to go back to 60's to late 70's to find a V-8 cyl head that uses crush rings

I know this is an old thread, but how are these working for those of you who purchased them?

 

[winchested]

They aren't. Everyone runs Motocraft Sp 534 and all the tuners seem to reccomend staying with these plugs as well.

 

[2Canches]

Yup ^^^^^^^^^

Is it the same number for the 15's? Maybe I should consult the all mighty owners manual. As my mods progress, I'm going to eventually have to address the plugs. I must say they look like some of the easiest plugs to change. My 4.0 Ranger is/was a PITA, but I've done them many times, so they're easy for me. It took a lot of bars of soap, and many beers to perfect, but I can change them out in about 20min.(OHV4.0 w/1.58" JBA headers)

Thanks!

Get the newest, flutter is gone.

Any tune I run, I get a flutter under load. Mostly when I am in 6th and start building boost... it goes away when the truck downshifts into 5th and the rpms are higher. What are the possible causes?

You need to log and send it to your tuner for evaluation, but first tell him what's it's doing, he might just know the problem is and send you a new tune(s)

Correct! Finally got a decent log of it. Talking about it now! Thank you Mr. B!
