Spark plugs for vortech?
 

Hey Guys!
I just got my 4.0/v6 2006 mustang back from the shop that installed the Vortech v3 HO. I still have the stock plugs with 22,000 miles and the can tune from Vortech.

Tell me something, I should try to stay out of boost right now, because of the plugs and can tune?

The mechanic at the shop is telling me about one step colder motorcraft spark plugs are better for my car then the NGK TR-6, could this be true?

What plugs do you think would be good for my ride?
Thanks

Autolite HTO's.

They're kinda pricey, but it's what all the performance shops around me recommended when I replaced mine about 2,000 miles ago.

cross referance teh one step colder motorcraft plugs with autolight (autolight makes ford plugs) and just use those, IMO some of the best plugs for boost are Halos but autolights are fine to

Thanks guys

I'm going to stick with the NGK TR-6's
Thanks

get the autolite 5143's. thats what i use in my car. i too have a vortech.

once again, i will say listen to dwis lol get the autolite 5143's. cheap and yet very good plugs. chosen by doug at bamachips and dave at EE for the X-Charger, and used in the powerhouse turbo setups as well. that should give you an idea how good they are.
