New Plugs??
I have changed my plugs recently, putting in the ngk's instead of the champion that were already in her. What else should I change to get the most out of those performance plugs?

Borg Warner ... the ones for the trucks or vans.. cheaper... reason why u not get the Camaro ones is they're 7mm while the other ones are 8 mm

if you have headers then the 1991 suburban 5.7L tbi ones are 8mm and pretty cheap from AC delco with 90' boots on all wires
