Love the quality of all zzp products. They got there stuff together with these 3800 Series GM supercharged motors! Everything I've bought from zzp has been a+ quality, and I don't mind paying a bit more for quality and dependability, and zzp has a awesome reputation, I now c why... I've bought there smaller pulley an belt kit, colder plugs, 10.5mm wires, colder thermostat an gasket, and my nex purchase is the zzp coil packs. 1 by 1 I'm getting everything I want an u can notice and actually feel the difference with the added power! Better mpg, and more torque I've got outta mine :)
United StatesSpark plug wires
Excellent fitment and good looks
United StatesGood Stuff
I replaced my coils, wires, and plugs all at the same time and I can say these are pretty sweet. I had old old ACDelco wires and these rock it. Due to their thickness I couldn't route them all the exact way they were before, I can see why people say they're a little short I couldn't get wire 6 to route the same way as the others. These with new plugs and the high voltage packs have given my 04 Grand Prix NA some *****. She starts up clean and holds nicely now.
