An MSD ignition box under your hood contributes to the complete burning of all the air and fuel you supply your engine
No matter how good your intake, exhaust, and injection system is, if you don't have an MSD ignition to light the mix it's all going to waste
MSD spark plug wires can deliver all the high voltage sparks MSD is famous for without radio interference
You can add MSD ignition parts like caps and rotors to your HEI ignition and improve the spark without a full-bore MSD installation
Leave it to two missile engineers to create the best-selling performance ignition of all time, but that's exactly what happened: You know their invention as the MSD ignition, which stands for multiple spark discharge. And the name says it all. An MSD ignition system is so effective because it allows for multiple sparks per combustion cycle, practically ensuring that the fuel/air mixture will be fully burned. We all know that the more complete combustion you get, the more power you produce, so that's the formula by which MSD ignition products produce horsepower. MSD ignition works off a principle called capacitive discharge, the basics of which are produced in the famous MSD ignition box that is a part of most MSD ignition systems. But MSD ignition is about much more than just the capacitive discharge box. That's because MSD ignition has become synonymous with high quality ignition parts of all types, including tune up parts, billet distributors, plug wires, coils, and magnetic trigger systems. Of course, MSD ignition parts work best when they're combined with each other into a potent system, but MSD ignition parts can also be added piecemeal to an older points system in order to achieve modern results. For all your ignition needs, check first to see if there are MSD ignition parts available. You can save money over rebuilt or lesser quality parts and you always get increased power because of the increased spark delivered by your MSD ignition parts.It's amazing that even on late-model cars and trucks, the distributor cap is still relied upon to provide accurate, complete spark energy to light off the fuel/air mixture (the exception being on the newest distributorless ignition systems, of course). Since the distributor cap remains such an essential component in your ignition, rely on a premium quality MSD distributor cap for your vehicle. Instead of using cheap plastics and aluminum terminals, an MSD distributor cap is constructed of alkyd resins that don't conduct any electricity and resist carbon tracking and moisture condensation. The terminals on an MSD distributor cap are brass for the best possible conductivity, and terminal gaps are precisely located on the MSD distributor cap to reduce spark scatter. Thick bases and molded vanes, along with dual hold-down mechanisms, are employed on every MSD distributor cap to ensure firm, accurate seating on the distributor base. Want more? Step up to a Pro-Cap MSD distributor cap. The Pro-Cap MSD distributor cap uses a special Rynite resin in its construction that provides maximum strength and heat resistance for even better durability. So, even if you aren't running any other MSD components, an MSD distributor cap can give you a hotter, more accurate spark, and that's one giant leap towards more horsepower and better reliability from your ignition system.Made to the same exacting tolerances as everything MSD supplies, MSD spark plug wires deliver the juice in a big way. MSD spark plug wires are designed with two goals in mind: Optimum power transfer and minimum RF interference. The two goals are frequently mutually exclusive, but MSD spark plug wires utilize new technological breakthroughs in spiral-core wire design to provide the lowest resistance possible while still maintaining excellent RF shielding. Super Conductor MSD spark plug wires have the lowest resistance of any wire of their kind (non solid-core street wire), but they have the RF shielding of a wire with 30 times their resistance! To give you an example of how tightly wound the coils are in these MSD spark plug wires, MSD claims that each foot of wire contains 40 feet of wound copperthat's a lot of winding. For those of you on a tighter budget, try Heli-Core MSD spark plug wires. These MSD spark plug wires feature a lot of the same technologies found in Super Conductor wires but built into more affordable MSD spark plug wires. All MSD spark plug wires are available in custom sets for most popular applications, with universal sets and bulk wire also available. Give your spark plugs a special delivery of high voltage the best way you know how: Install MSD spark plug wires on your car, truck, van, or SUV and see horsepower and fuel economy improvements.
