Will These Spark Plugs Do With My Combo

[lovinspeed]

Good Day All

I have a 91 5.0 with a paxton SN93 supercharger (still has stock injectors, heads, mass air). This is my first time with a supercharger, so my expierence is lacking. My question is, will Champion 25cc spark plugs do or do I need colder plugs?

Also, what do you recommend the gap should be?

Thanks for your replies

I would go with an Autolite 23 or 24 for your car gapped @ .032

I second the autolite 23's gapped .032-.035"

Thanks for the replies. I live in a small town in Northern Ontario, Canada. We only have a Canadian tire store. Does anyone know of a place to buy autolites online?

So the Champion 25cc are no good? Anybody from Canada know of another brand that is good, that would be available at Canadian Tire.

Thanks

5.0 Mustangs tend to love Autolite/Motorcraft plugs, i would run these.


I beleive autozone sells them online. You could also go to Ford. I don't know Ford's number system for plugs that are one range colder than the 42C.
