MSD 8.5mm Super Conductor Spark Plug Wire Sets

MSD 8.5mm Super Conductor spark plug wire sets feature a special helically wound core that has just 40-50 ohms of resistance per foot—but with an RFI suppression equal to a 1,500 ohm wire. In fact, each foot of finished wire includes 40 ft. of tightly wound copper for superior conductivity. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference "choke." This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. A tough, 8.5mm synthetic/silicone jacket over an extra-heavy glass braid and dielectric insulator keeps the current guided to the plugs. Underneath the high-temperature boots, dual crimp stainless steel terminals feature snap-locks to ensure a secure fit. Each set comes with clip-on cylinder markers for easy identification. MSD's 8.5mm Super Conductor wire sets are available in custom or universal-fit applications, assembled or not, with a variety of terminal and boot end options.

XS Power AGM Batteries

XS Power AGM batteries are some of the lightest racing batteries on the market. Independent test results have proven that they outperform other battery models that outweigh these power providers by up to 20 lbs. Cutting-edge lead acid battery technology produces more energy in a smaller space because each cell is compressed before case insertion, resulting in efficient power-producing packages that are completely sealed with no need to ever add water. This design is ideal for the abuse of racing, making these the batteries of choice for demanding racers and Monster Truck drivers who need top performance and reliability. When you are pushing to power the impossible, you need the non-stop capabilities of the XS Power AGM batteries best suited for your application. Product features include: * Designed to be an inch shorter than what the competition offers for fitting in places where space is at a premium * Deep-cycling ability and ultra-low internal resistance results in high cranking amps and excellent vibration resistance * Variable position mounting (except upside-down) thanks to the no-spill design * Offered in 6 V, 12 V, 14 V, and 16 V models

NGK V-Power Spark Plugs

NGK V-Power spark plugs offer economical performance for nearly any automotive application—and they're the only plugs with NGK's V-Groove technology. These plugs enhance ignitability, lower the voltage requirements of ignition systems, and have strong anti-fouling characteristics, while improving fuel mileage and acceleration performance. The V-Power plugs are also highly durable against electrical and chemical wear, making them long-life replacement plugs. Because of the V-Groove, the spark occurs at the edge of the center electrode—so heat is not absorbed by the electrode itself. This allows the flame kernel to expand quickly and efficiently for a complete burn and great performance. More than a hundred models are available, both universal and application-specific; order the plugs designed for fitment on your vehicle.

MSD Pro-Billet Ready-to-Run Distributors

MSD Pro-Billet Ready-to-Run distributors are the perfect upgrade for weak OE electronic distributors, outdated points distributors, and large HEIs or DuraSparks. All that's required is to install the distributor in the engine, and connect three wires and the coil! A maintenance-free magnetic pickup accurately triggers this ignition with increased output from the amplifier, easily outperforming stock ignitions. It will smooth out the engine's idle, improve starting, and perform at a much higher rpm. The housing is machined from billet 6061-T6 aluminum, using state-of-the-art CNC mills and lathes for a unit with no porosity or weak areas. For stability and endurance, an oversized steel shaft spins in a top-mounted sealed ball bearing, while an extra-long sintered bushing guides the shaft at the base of the housing. This shaft also receives a QPQ coating for low friction wear and resistance against corrosion from humidity and ozone buildup. The distributors feature MSD's adjustable mechanical advance, which allows you to custom-tailor an ignition curve to match your engine's needs. Most models are also available with a vacuum advance canister to help improve economy. Order the model recommended for your vehicle and engine application.

MSD Ford Blaster Coil-on-Plug Ignition Coil Packs

These MSD Ford Blaster Coil-on-Plug ignition coil packs feature a patented winding design and direct bolt-in replacement. The improved spark energy and voltage of the coil packs, combined with their reliability, have made them a favorite of performance enthusiasts. They are designed as direct bolt-in replacement coils for many SOHC Ford V8 modular engines. The housing and installation are the same as the factory coils, but that is where the similarity ends. Inside the MSD coil packs, engineers used better quality materials to assemble the primary and secondary windings. The MSD Ford Blaster Coil-on-Plug ignition coil packs take the spark energy right out of the coil and put it across the plug gap to improve the combustion and output of the engine.

Summit Racing™ Digital RTR Plus Billet Distributors

We've taken our original Ready-to-Run billet distributors and upped the ante with our Summit Racing™ Digital RTR (Ready-to-Run) Plus billet distributors. They now feature a digital module with a 7.5 amp rated dwell control circuit for maximum energy output. They deliver 400 volts and 125mJ of spark energy to the coil and upwards of 50,000 volts from the coil to the spark plugs. We've also added a single-stage rev limiter with a simple "tap to ground" process of the tachometer lead attached to the module to set the limiter. The tachometer dual purpose lead also produces a 25 percent duty cycle, square wave signal, so it can be used with multifunction tachometers and most popular aftermarket EFI systems. Another bonus feature of our digital technology is a fully automatic start retard. This built-in feature provides 4 degrees of timing retard during cranking and is fully dialed out by 300 rpm. This gives you easier and quicker hot restarts while lowering the initial start load on the starter and electrical system. With all these upgraded features, you're assured of peak output throughout all RPM ranges, quicker hot starts, EFI capability and the reliability of digital technology. The distributors still have the same lightweight, forged, precision CNC-machined aluminum housing for strength and stability; polished steel shafts with sealed ball bearings for stable operation through 10,000 rpm; and a maintenance-free, high-output magnetic trigger for accurate and reliable performance. All distributors come with a high-quality, 30 percent glass-filled PBT cap and rotor with brass terminals and contacts. An ignition box is not required for use with Summit Racing™ Digital RTR Plus billet distributors except when used with an aftermarket EFI system. Select the model recommended for your car, truck, or van.
