I have Bosch Platinum +4. Mostly because I want fouling resistance, longer life and no gapping.

I used the regular AC plug, but whatever you do, make sure you have the right plug for your engine. In 86 they switched heads from iron to aluminum and they are different plugs. The owners manual that I have only had the plug number for the iron head engine. As a result, my car had the wrong plugs in it when I got it. I replaced them with the right plugs and got 2mpg better.

I like NGKs. They seem to work great for me. I don't see the sense in plat plugs since I try to change my every year or so.
