One of the most important part of your engine is the distributor. This is the device that transfers that spark from the electric system to the spark plugs, and is responsible for the timing of that spark. If it's not happening at exactly the right moment, you've got problems. Unfortunately, with so many "American" car manufacturers outsourcing jobs to places like Mexico and China, many of these foreign-built OEM components are of inferior quality and may wear out prematurely. The MSD Distributor is build right here in the USA, using good honest American labor that produces the kind of American-made quality that was once the envy of the world. MSD is a division of Autotronic Controls Corporation, which was founded by two engineers from White Sands, New Mexico. Their specialty is performance racing components that are optimized for a range of driving conditions. The MSD Distributor that most drivers choose is the Pro Billet Ready-To-Run model, which is a stand-alone device that requires no additional upgrades. With an MSD Distributor, you'll enjoy smoother idling, quicker start-ups, and a wider rpm range. With a durable, oversized shaft, you can adjust the ignition curve for your own driving style.
