the lt5 has a very efficient combustion chamber and the stocker stuff works great to 700 hp
I've tried all the fancy plugs and wires and stuff and like the
ngk
delco
denso
all work really well and I've dynoed the car and can say there really isn't any difference
I would recommend the delcos and change them more often as it's good to inspect the plugs
last time I pulled $6 water shot out
