HPI4 - High Power Igniter - Quad Channel - Module Only

Overview

The Haltech HPI4 High Power Igniter delivers the high-energy spark control that forced induction and high-compression builds demand. This quad-channel ignition module transforms your ECU's low-current signals into the powerful spark energy needed to reliably fire high-performance coils, ensuring consistent combustion even under extreme boost conditions where standard ignition systems falter.

Technical Specifications

• Part Number: HT-020032
• Channels: 4 independent ignition outputs
• Output Type: High power ignition switching
• Configuration: Module only (harness sold separately)
• Control Method: ECU triggered ignition timing

Why You Need This

High-performance builds with aggressive timing maps, significant boost pressure, or high-flow coils quickly overwhelm standard ECU ignition outputs. The HPI4 solves this by providing dedicated high-current switching for each cylinder, preventing the weak spark and misfires that plague builds pushing serious power. Whether you're running a highly-tuned 2JZ-GTE build, an LS swap with individual coils, or an RB26 with uprated ignition components, the HPI4 ensures your spark energy matches your engine's demands.

Without proper ignition amplification, ECUs struggle to drive modern high-output coils effectively, leading to inconsistent firing, reduced power output, and potential engine damage under load. The HPI4's quad-channel design is perfect for four-cylinder turbo builds like SR20DET or 4G63 applications, or can handle half of a V8 setup when paired with additional modules. Our workshop regularly fits these to customer builds where standard ignition systems have proven inadequate for the power targets.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range, including Elite 550/750/1000/1500/2000/2500 and Nexus R3/R5 systems. The HPI4 integrates seamlessly with Haltech's ignition control strategies, allowing precise timing control while providing the current capacity your high-performance coils require.
