E3's line of DiamondFire matched ignition products features all of the components needed to produce a well-integrated ignition system. The components are designed as a complete system but can also be used as stand-alone parts. E3 offers everything from distributors to coils, all complementing the company's race-proven DiamondFIRE spark plugs. E3’s DiamondFIRE race wire features an 8mm silicone outer jacket, a silicone inner jacket and stainless-steel terminals. The wire uses a class-F40 spiral conductor that has just 30 ohms of resistance per foot. That’s the lowest resistance possible, ensuring the maximum amount of power is delivered to the spark plugs. DiamondFIRE ignition wires are designed for a direct OEM fit and are available for most popular applications. The high-quality core provides unmatched strength as well as high-temperature durability. Surrounding the core and stainless-steel windings, a layer of latex silicone enhances conductive efficiency and core stability. Boots are available in straight or 90-degree configurations.

DiamonFIRE 6CDI Ignition Systems

Any attempt to boost engine performance should begin with an ignition-system upgrade. Engine modifications that increase the fuel mixture entering an engine or that squeeze the mixture a bit more densely while elevating the rpm ceiling can produce significant performance gains, but only if the charge is effectively set aflame at the correct moment on every cycle. Such engine modifications make it tougher for a stock ignition system to keep pace. So why not first install an upgraded high-performance ignition system to fully reap the benefits of the engine tweaks? E3’s new DiamondFIRE line includes all the components needed to produce well-integrated ignition systems equally at home on the street, in the dirt or at the track. The components are designed to function as a complete system but can also be used as stand-alone parts. E3 now offers everything from distributors to coils, all complementing E3’s proven DiamondFIRE spark plugs. The ignition-system line, introduced at the 2017 SEMA Show, includes a billet racing distributor (shown here), DiamondFIRE 8mm high-performance or racing spark plug wires, a digital capacitive discharge ignition box (DiamondFIRE 6CDI), a high-output CD coil, an external two-step rev control, race O2 sensor, electronic oil-filled can coil and E3 high-output performance coils.
