Hello, just purchased a 96 Cobalt 200 with a 5.7 LX EFI Mercruiser powerplant. Looking to do a full tune up, I read through the owners manual and am planning on doing all the lubes, filters, wires, plugs and cap and rotor. Does anyone have any recommendations as to a good brand name for the filters, wires and cap? My local NAPA sells tune up parts for my specific engine, has anyone had any luck with NAPA marine parts?
