I have an 86 camaro that I swapped a 3.4 v-6 in. I am using the 2.8 spec spark plugs and I was wondering what the best plug is for this motor with the 1986 igniton system. I have a new cap, rotor, wires and ana accel supercoil. Also have k&n filters.

I am understanding that autolite is a superior plug. What is the best plug for my applicaton?

 

I like runing the acdelco rapid fire. Cost per quility.

I belive autolite is the only "truely enginereed" plug. I had them in my dodge, didn't notice a difference over any other plug.
