I'm fixin to change the optispark and water pump on my C4 ... i'm keeping the car pretty much stock .... there seems to be a million sources for parts, so was wondering what y'all's recommendations might be ....
Gerry, I've got a 94 coupe that I completed this year and went with an MSD Optispark ignition from Summit Racing and a new (not remanufactured) water pump from Bosch that I got at Pep Boys. Both parts are nice, well made pieces. I've had issues with NAPA water pumps and reman units. Hope this helps.
