Mallory’s UNILITE (R), and magnetic breaker less ignition modules are self contained module assemblies which have no moving parts to wear out. Using Mallory’s time tested breaker less ignition circuit, combined with modern surface mount thermal-clad construction, these ignition modules can drive both OEM and high performance ignition coils. For best results always use a Mallory PROMASTER coil or a Mallory chrome electronic ignition coil. These are also an excellent choice for triggering one of the Mallory HyFire series of electronic ignition controls. Hookup is as easy as a three wire connection.

• Service Part
• No Moving Parts To Wear Out
• Self Contained Unit
• Can Drive OEM
• Can Drive High Performance Ignition Coils

For a long time, racers have known that one of the best things to do to an engine to improve its performance is to stabilize the ignition timing. The MSD flying magnet crank trigger system does exactly that by using magnets embedded in an aluminum wheel. The MSD flying magnet crank trigger uses four magnets secured in the aluminum trigger wheel that pass by a stationary non-magnetic pick-up to trigger the ignition. This flying magnet design produces accurate trigger signals and the non-magnetic pick-up cannot be false triggered. Each flying magnet crank trigger includes a two-piece mounting bracket for the non-magnetic pick-up that in most cases will work on either the passenger side or driver’s side of the engine (the SB Chrysler and SB Ford brackets mount on only one side). The adjustable bracket provides a wide range of timing adjustment and spacers are included. These systems will trigger MSD 6, 7, 8 and 10 series ignitions and all MSD timing accessories.

Product Features:

• 6.25 in. Diameter
• Absolutely the most accurate way to trigger the ignition.
• The non-magnetic pickup cannot be false triggered.
• Powerful magnets are embedded in a billet aluminum trigger wheel.

HEI owners now have a choice to replace their stock coil with the MSD high energy unitized coil for GM HEI distributors. This coil is a direct replacement of the stock coil and offers increased spark energy when used with the MSD HEI module, PN 83645. The coil features special low induc?tance, high temperature windings which charge faster to give you increased spark energy at higher rpm. The premium epoxy filled construction is designed to withstand harsh race applications as well as the wear and tear that daily usage dishes out, and still deliver more spark energy to the spark plugs.

Product Features:

• Direct performance replacement for GM HEI coil-in-cap dist.
• 70:1 Turns Ratio
• Lower Primary Resistance Produces High Voltage Output
• Full Power Sparks To 9000 Rpm w/PN[83647] MSD HEI Module

Engineered with optimized low resistance, high turns ratio windings around an M36 high silicone magnetic steel E-core for higher energy and voltage outputs. Compatible with late model GM computer controlled remote mount HEI systems. Direct bolt-in, plug-in replacement. Brass coil wire contact increases energy transfer and resists corrosion better than aluminum. Complete with new mounting hardware.

The traditional ACCEL combination of yellow wire and red spark plug boots has been added to these SuperStock Spiral Core 5000 Series wire sets, which feature color-matched wire and spark plug boots in blue, black, and red. With only 500 ohms/ft. of resistance, more ignition energy can reach the spark plug, producing a longer-lasting, hotter spark flame kernel. The results is higher performance through improved efficiency, quicker throttle response, and reduced emissions. This 8mm wire’s double silicone construction is rated to 550 degrees F. The high-gloss wire jacket resists moisture, chemicals, and heat extremes for longer life and great looks. The fiberglass braid adds greater pull strength and terminal retention, while the stainless steel spark plug terminals provide excellent long life, electrical conductivity, and corrosion resistance. Both universal and custom-fit applications are available for early and late model cars and trucks.

The MSD 8.5mm super conductor wire is the performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference. In a single 12 inch length of super conductor wire there is only 40 – 50 ohms of resistance. That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it’s great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective electro magnetic interference (EMI) or choke. This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. Available in universal kits and bulk lengths.

Product Features:

• Less than 50 ohms per foot for superior spark
• Ferro-magnetic impregnated core creates an effective EMI choke
• 40 ft. Of Conductor Wound Into A Single Foot Of Wire
