E3 Spark Plugs Introduces Full Line Of Performance Ignition Products

New from E3 Spark Plugs – their expansion into a full line of race and street performance ignition products. These products are all designed to complement the DiamondFIRE spark plug. See more details below.

Official Release:

E3 Spark Plugs announces expansion into a full line of race and street performance ignition products; all designed to complement the company’s high output DiamondFIRE spark plug. The ignition line that was introduced at the 2017 SEMA Show, includes DiamondFIRE racing spark plug wires, street distributors, a 6CDI ignition box, a high output CD coil, an external 2-step rev control, race O2 Sensor, electronic oil-filled can coil and E3 high output performance coils.

E3s new DiamondFIRE Billet Distributor line developed for street and most race series is designed to have an OE fit for the most common Chevy, Ford, and HEI applications. Top mounted, they come complete with the cap, rotor, wire retainer and a fully adjustable mechanical advance curve kit. Each DiamondFIRE distributor is CNC machined utilizing 6061-T6 heat-treated aluminum housing; a hot forging process that eliminates weak spots and porosity. The adjustable mechanical advance features a cam plate and weights that are precision-stamped and blanked for on-target accuracy, dimension and balance. The high output magnetic pickup is engineered specifically for racing in the harshest motorsports environment.

E3s new 8.5mm DiamondFIRE Race Wires sport a class F40 spiral conductor rated at 40 Ohms per foot. The 100% silicone outer jacket encases a 100% silicone inner jacket with stainless steel terminals for added durability. Boots are available in straight or 90° configurations.

The DiamondFIRE 6CDI Ignition Box, drawing only 0.7 Amps per 1,000 RPM, delivers 525 volts to the coils and up to 130mJ of spark energy.

E3s new DiamondFIRE High Output CD Coil is engineered to work with the E3 6CDI capacitive discharge ignition box and other popular 6 series street/strip CD ignition control boxes. The design of the E-core and the use of heavy gauge windings produce a high voltage step-up transformer to ensure the fastest possible delivery of the most energy.

The External 2-Step Rev Control designed specifically for drag racing allows a lower rev limit in the starting and staging lanes. Two easy to read rotary dials allows changes in the stage rev limit in increments of 100 RPM.

E3s new Race O2 Sensor has a pre-terminated connector for quick installation and is designed to deliver improved engine response, regardless of race application – drag, road or oval, while ensuring a longer sensor life and reliable performance.
