Overview
The Haltech HPI8 High Power Igniter transforms eight-cylinder builds with bulletproof ignition control that leaves factory systems in the dust. Purpose-built for high-performance applications where standard ignition simply can't deliver the spark energy needed, this complete 2-metre flying lead kit handles everything from naturally aspirated LS builds to heavily boosted rotary conversions.
Technical Specifications
- Part Number: HT-020043
- Channels: 8 independent ignition outputs
- Lead Length: 2.0m (78 inches)
- Output Type: High energy CDI ignition
- Configuration: Flying lead harness with module
Why You Need This
Factory ignition systems hit their limits the moment you increase compression, add forced induction, or push RPM beyond standard parameters. Weak spark energy causes misfires under boost, incomplete combustion at high RPM, and power losses that leave potential on the table. The HPI8 delivers consistent, high-energy spark across all eight cylinders, ensuring complete fuel burn even in demanding conditions like 20+ PSI boost or 8000+ RPM operation.
This kit excels in builds where ignition timing precision matters most — LS swaps running E85, RB26 conversions with big turbos, or any application where you're pushing beyond factory power levels. The 2-metre flying leads provide installation flexibility for engine bay layouts where space is tight or the ECU mounting location requires extended reach. We've seen this system transform problematic high-boost builds that suffered from spark blow-out into reliable, consistent performers that hold timing under the most demanding conditions.
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 HPI8 integrates seamlessly with Haltech's ignition control strategies, allowing full timing map control and individual cylinder trimming.

Complete Your Build
Most customers completing an HPI8 installation also add quality ignition coils and spark plugs suited to their specific application — whether that's LS coil-on-plug setups or traditional distributor-less systems. Our technical team can recommend the complete ignition package for your build, ensuring proper coil matching and spark plug heat range selection. With UK stock and expert pre-sales advice, we'll have your ignition system sorted without the guesswork or extended lead times from overseas suppliers.
