Ordered my custom length firecore wires at 11:55 got a shipping notice email at 1:01 have to like that turn around
12 Years ago I dynoed a new set of firecore wires vs a new set of msd. Dyno operator said I was wasting my time until he seen the results got over 5 hp from nothing but the wire change. This was on a 735 hp pump gas engine.
Been my first choice ever since.
