ACCEL’s SuperStock 4000 series spark plug wire sets are designed to upgrade an OE ignition system for high-spark delivery levels for street driven applications. The 450 degree F rated silicone jacket is extruded over a tightly woven, rugged fiberglass braid. The braid is applied over high dielectric strength EPDM (Ethylene Propylene Diene Monomer) inner insulation for ignition wire performance that exceeds SAE specifications.

Product Features:

• 7mm And 8mm High Gloss Silicone Jacket
• 450 F Rated Silicone Jacket
• Stainless Steel Plug Terminals
• RFI Suppression For Street Driven Applications
• Custom-fit Universal And Import Coverage
• High-strength Fiberglass Braid Construction

The MSD 8.5mm Super Conductor is the ultimate performance wire. Its extremely low-resistance combined with the ability to suppress Electro Magnetic Interference is a combination that defies the common laws of physics.

Product Features:

• Less than 50 ohms per foot for superior spark
• Ferro-magnetic impregnated core creates an effective EMI choke
• Forty feet of conductor is wound into a single foot of wire for high EMI suppression
• Conductor core features Dupont Kevlar material for increased tensile strength
• Durable outer sleeve is a proprietary compound for resistance to high heat or abrasion
• Proprietary compound sleeves for resistance to high heat/abrasion

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) “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. The MSD’s 8.5mm spark plug terminals feature Dual Crimp terminals. As the name implies, the terminals feature two crimps; one for the sleeve of the wire and another separate crimp to grasp the conductor.

For a long time, racers have known that one of the best things to do to an engine to improve performance is to stabilize the ignition timing. The MSD Flying Magnet Crank Trigger system does exactly that by using four magnets embedded in an aluminum wheel. Although similar in appearance to other crank triggers, the MSD Flying Magnet design works on a different principle. Most crank triggers have a wheel, with steel studs sticking out, bolted to the harmonic balancer. As the crankshaft turns, the studs pass by a stationary magnetic pick-up, triggering the ignition. This pick-up can be triggered by other bolts, debris, or even vibrations which will cause a loss of power or engine damage.

Product Features:

• 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.
• Kits feature special brackets and mounting hardware for a variety of engines.

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 falsely 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 CNC-machined aluminum bracket securely holds the pick-up in place and is slotted to provide a wide range of timing adjustments. Spacers are included so you can mount the bracket on engines with standard motor mounts or engines with a .25″ motor plate. These systems will trigger MSD 6, 7, and 8 Series Ignitions and all MSD Timing Accessories.

• 7″ 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.
