Description
The Haltech V8 GM/Chrysler Hemi High Output IGN-1A Inductive Coil and Harness Kit is the premier ignition upgrade for high performance Small Block and Big Block V8 engines. When pushing the limits of forced induction, high compression, or nitrous, standard ignition systems often suffer from spark blowout due to extreme cylinder pressures. The IGN-1A inductive coils are engineered to solve this, providing a massive, high-intensity spark that ensures complete combustion and reliable power delivery even under the most demanding conditions.
This kit provides a professional, direct plug ‘n’ play solution for owners of Haltech E2000/2500 V8 Terminated Harnesses, as well as Elite + REM systems. By moving to an individual coil per plug configuration, tuners gain the ability to precisely control ignition timing and dwell for each cylinder, leading to improved engine smoothness, better throttle response, and increased top end power. The coils feature built in ignition modules, removing the need for external igniters and simplifying the engine bay’s wiring architecture.
Durability is at the core of this kit’s design. The harness is constructed using high-spec Tefzel (Milspec) wiring, which is utilised for its superior resistance to heat, oil, and chemicals; essential for the harsh environment of a high performance V8 engine bay. To manage the high current draw required by eight high output coils, the kit includes a heavy duty 75A TE power relay, ensuring consistent voltage is delivered to the spark plugs regardless of engine RPM.

Frequently Asked Questions
Why should I choose IGN-1A inductive coils over a CDI system?
While CDI (Capacitive Discharge Ignition) systems provide a very short, high voltage burst, IGN-1A inductive coils provide a much longer spark duration. This longer duration is often superior for igniting rich fuel mixtures in high boost applications, leading to better combustion stability and reduced risk of misfires.
Is this kit compatible with other ECU brands?
While the harness in this kit is specifically terminated for Haltech V8 harnesses (such as the Elite 2500), the IGN-1A coils themselves are universal. If you are using a different ECU, the coils can be utilised, but custom wiring or a different sub harness may be required to match your specific pinouts.
What makes Tefzel wiring better for a performance car?
Tefzel (ETFE) is a high performance fluoropolymer insulation. It is significantly thinner and lighter than standard automotive wire while being far more resistant to abrasion, high temperatures, and engine fluids. This ensures that your ignition harness will not become brittle or fail after repeated heat cycles in a performance engine bay.
Do these coils require a specific dwell time setting?
Yes. To get the best performance out of the IGN-1A coils without overheating them, your tuner must set the dwell times correctly in the ECU software. These coils are capable of handling high dwell for short bursts, making them perfect for drag racing and high performance street use.
