twin turbo spark plugs
 

hello
can anyone tell me if i should put colder or hotter plugs
on my 89 lx 302 twin turbo
thanks

Im sure you are totally fine with factory Ford Motocrafts, or even auto lites...Im not sure what you should run for a GAP, but I am sure someone else can chime in.

I am still using Motocrafts in my Supercharged 302.
Good luck :)

You should be running one or two ranges colder plugs, and depending on boost, gap them around .024"(high boost will casue spark blowout"no:

autolites ones stage colder for up to 10psi, 2 steps colder after that is a good rof thumb. each car is different.find out what your car likes.
