Re: Identifing a 2.3 Motor?

A lot of folks say to only use Ford Motorcraft ignition parts because aftermarket items can be problematic.
Use copper plugs. NGK 2238 or Motorcraft SP447 AGSF32C, there's some others that are good too. You'll want to decrease the spark plug gap too according to how much boost you run in the car to avoid spark blowout. I am currently running .028" with 17 psi that is probably lower than it needs to be.
