What's up, I've been communicating with rob_e30 about the COP kit and I'm going to order it in a few days, but from what I've read, it should give you a better throttle response. I'm not one to spend my hard earned cash for something that I may have a doubt with, but I will sometimes look a things as a scientific tests or analogies..when the question arose if something could possibly work or not. The way I've been searching to give the "PROOF" any and every horse possible without breaking my bank is worth it to me. Will they show any type of an improvement? I'm not a 100% certain(but) the way they connect directly to the spark plug gives me the -yes go ahead and purchase green light.
