HPI4 - High Power Igniter Quad Channel 2m Flying Lead Kit Length: 2.0m (78")

Overview

The HPI4 High Power Igniter transforms ignition performance on high-boost and high-compression builds where standard ignition systems fail. This quad-channel unit delivers massive spark energy through four independent channels, ensuring complete combustion even under extreme cylinder pressures that would blow out conventional coil systems.

Technical Specifications

• Part Number: HT-020035
• Channels: 4 independent high-energy outputs
• Flying Lead Length: 2.0m (78 inches)
• Configuration: Complete kit with HPI4 module and wiring loom
• Output Type: High-energy capacitive discharge ignition

Why You Need This

Standard ignition coils simply cannot maintain consistent spark energy when cylinder pressures exceed 40-50 PSI boost or compression ratios push beyond 11:1. The result is misfires, knock, and power loss exactly when you need maximum performance. The HPI4 solves this by delivering capacitive discharge ignition with energy levels that dwarf conventional inductive systems — think drag strip reliability for your street build.

This system excels on forced induction applications: turbocharged LS swaps running E85, big-turbo RB26 builds, 2JZ setups pushing serious boost, or naturally aspirated engines with aggressive cam timing and high compression. Where other ignition systems struggle with dense air-fuel mixtures and elevated cylinder pressures, the HPI4 maintains clean, complete combustion. The 2-metre flying leads provide installation flexibility for engine bay layouts where remote mounting is required, particularly useful in cramped swap applications or race car builds.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range including Elite 550, 750, 1000, 1500, 2000, and 2500 ECUs, plus Nexus R3 and R5 systems. The HPI4 integrates seamlessly with Haltech's ignition outputs, providing the high-energy spark delivery these advanced ECUs are designed to control.
