Is it possible?

Does anyone know if there are any type of performance spark plug wires one can put into the 2001 Chevrolet Venture?

Has any one rereplace the factoy battery with an optima? If so which one.

Also I know its a long shot is it possible to put a sunroof in the van? I know I am reaching a bit especially with the overhead console!

As for the wires, try:
