I been trying to find the best plug for the 2.3 T engine. When u go to a parts house it seems that they give u the same spark plug that the n/a engines uses. Does anyone have the Motorcraft part number for the Turbo engine?
Shouldn't the plug heat b at least one or two heat levels lower (meaning a colder spark plug) on the Turbo engine verses the n/a Engine? Thanks for any input....

We run ngk in all our race car stuff... I'd bet a couple boxes of spark plugs there's more ngk and auto lite spark plugs in high horse power cars than any other plug on the market.
We prefer ngks because they are a little more forgiving than the thick ground strap of an autolite
Just my .02

Jeez, ten seconds on rock auto as i recommended would have gotten you the info you requested MOTORCRAFT Part # SP447 More Information About this Part {#AGSF32CF6} Standard Gap: .034 |

And if that bet pertains to 2.3 turbos ( we are on a 2.3 turbo board after all) I will take you up on it. |

What's the bet?
Which plug lasts longer? which plug you Can make the most power?
I'll be honest with my personal results
I don't care to be wrong
You know why they choose motorcraft?

Does motorcraft make a nonprojected tip plug?

AWSF-32C is the standard turbo plug that's good to 30+psi. It should cross to a NGK BPR6EFS or a TR55. One step colder is a TR6 (Motorcraft AWSF-22C), two steps colder is a BR7EF (Motorcraft AWSFA-12C). Note the TR55 is stock in a 4.6L Mustang GT/Cobra except the Supercharged 03-04 Cobra which uses the NGK TR6. There doesn't seem to be a "need" to go colder than stock until you're REALLY pushing it and then it's more of a "why not" than a "need". The "stick with motorcraft ignition" recommendation is true for setups running the stock coil and such. Once you go with a CDI ignition or some other option, it's no longer so finicky about what components are used. The recommendation also applies mainly to plug wires, cap, and rotor, not so much the plugs. NGK's are great plugs, I run them in everything I give a crap about but I did run Motorcraft plugs in my SVO before I swapped the head (which uses a non-stock plug style). No idea whether Motorcraft makes a non-projected tip. I've always wondered about running a plug like this in "extreme" applications:  |

Wish I would have tried that plug in my victor headed engine.. 500+ nitrous... 6degrees total timing... Think it would have saved me a piston or two.
Bischoff mentioned them late in the year, we just nevergot around to it. Probably will with thebig block
You Get into reading plugs at all? And if so how do projected tip plugs read timing mark compared to non projected tip?

I've done some plug reading but more of it on my Banshee than on my SVO. Only did it on the SVO when I dyno'd it and I didn't try different plugs then.

WHAT IS THE ADVANTAGE OF RUNNING A COLDER PLUG? DOES THIS MAKE THE SPARK NOT BLOW OUT UNDER BOOST??? ALSO WHAT ARE THE SIGNS OF SPARK BLOWING OUT? RICHNESS??IS IT LIKE YA GOT A 2 STEP AT HIGH R'S?

Please stop yelling (shut off caps lock).
Colder plugs don't have anything to do with spark blow out. That's related to plug gap and coil/spark strength. If the spark blows out it will fall on its face. Typically it will blow out at tq peak though when cyl pressure is the highest, not at high rpm.

well looks like i have been somewhat corrected. Good thing i dont mind being wrong either Eric lol. The main reason i was so insistent on the motorcraft plugs is through my years of reading archived threads on forums i cant count how many times people have had issues with stumbling, missing, breaking up, etc, and the first advice is always "use motorcraft ignition components and try again"
