I think too many people just use kid gloves... If those boots are stuck, it's time for new wires. Rip the suckers off and upgrade the wires. On the GTP I never had to pull the engine forward but to each his own, it is mostly by feel... Lol. On the GP I've had to pull the engine forward though as it is a bit tighter there. Also, plug wires are lengthened for the application, the wires from the other car may work but you'll probably have sagging cables/slack, not good IMO. Lastly, use some dielectric grease if you care to on plugs and coils when replacing wires or plugs... Will help with next removal. Lol
