I just purchased a 2003 cavalier LS sport model... my 00' cougar bit the dust... i wanted to replace the spark plug wires but it looks like the plug wires are built into the piece of plastic with the engine badge and the coil pack on it... i dont actually see plug wires in there... is it possible to upgrade the plug wires on this car?? if so how do i go about doing this?? thanks! corey

It doesn't use wires, Ecotec engines use coils/coil packs
