That big powerful engine needs a few things in order to do its job properly. It needs fuel, first of all. It requires air in order for the fuel to ignite properly. Finally, it needs a spark in order to create that contained explosion that actuates the cylinder and starts the crankshaft. (It needs lubrication and cooling as well, but those are other issues.) With any one of those elements missing, that engine will simply not operate. An MSD Ignition Wire Harness will go a long way toward ensuring that spark reaches the fuel-air mixture in those cylinders. The MSD Ignition Wire Harness is available in numerous styles and contains all the features you would expect from a component manufactured by a company with almost forty years' experience in the design and manufacture of products for high performance vehicles. Each MSD Ignition Wire Harness is designed specifically for the make and model into which it is to be installed, right down to the matching connectors and wire colors.
