    CAPACITIVE DISCHARGE IGNITION (CDI) IS ESSENTIAL FOR MAXIMUM PERFORMANCE. ENGINES WITH HIGH LIFT CAMS SEVERAL STEPS ABOVE STOCK, CAN BENEFIT GREATLY, AS A CDI SYSTEM WILL BURN FUEL IN LOW RPM RANGE VERY EFFICIENTLY. YOU WILL NOT SEE ANY SERIOUS STREET ROD WITHOUT THIS TYPE SETUP.

    SPACE DOES NOT ALLOW A FULL EXPLANATION OF ALL THE BENEFITS TO RUNNING A CDI SYSTEM. JUST ASK AROUND, AND YOU WILL SEE HOW MANY PEOPLE HAVE FOUND THIS SYSTEM TO BE A GREAT IMPROVEMENT OVER HEI SYSTEMS. INSTALLATION IS VERY SIMPLE. THE MSD UNIT COMES WITH A FULL SET OF INSTRUCTIONS.

    AS USUAL, WE ARE VERY SELECTIVE OF WHAT TYPE PRODUCTS WE SELL. THIS UNIT MEETS ALL OF OUR REQUIREMENTS: QUALITY, LOW PRICE, & PRACTICAL.

    NOTE FROM OUR COMPANY PRESIDENT

    Read up on the many benefits of running cdi ignition and you will be amazed at what you are missing. Engines with medium to aggressive cams cannot burn fuel efficiently in the low rpm range. This is due to the aggressive cam profile, large cylinder head and intake runners, and high cfm carbs that most all medium to high performance engines have. These type engines that have that so called lopey idle that doesn't smooth out till around 2000 or more rpm are responsible for much of the carbon build up in the combustion chambers, and occasional plug fouling when cruising for any length of time, not to mention this worsens the drivability, performance and fuel mileage.

    CDI systems improve combustion to such a degree that you will notice the difference in many ways. The intense multi spark function is the key to it all. If you have a medium to high performance engine, and are running an HEI distributor, then all the above issues mentioned will most likely become a reality to some degree. If you do have an above stock street rod engine with a conventional ignition system, then you are holding it back from its full potential, not to mention the other issues listed in this article by not running a capacitive discharge system.

    Even if your engine is not in the high performance range, this system will still offer improvements in may ways over an HEI distributor. Faster start ups, better low speed drivability, and improved fuel mileage. There are no drawbacks! The MSD unit comes with very clear cut installation instructions for use with many different type distributors.
