I just recently got a new motor put in my 89 cougar xr7 and the shop that installed the motor put in regular Autolite resistors with a gap of .040 and I was wondering if I were to change to the Autolite platinum or even double platinums would I notice a difference and what should I gap the plugs at since my car is completely stock. It seems to run fine the way it is now I can pull from a Z06 off the line but after that its toast. So should I keep the gap the same or take it to the stock .054 gap?? Thanks
