Buying Guide: Key Purchase Considerations
- Distributor compatibility: Confirm your distributor brand and model (Delco, Ford, Bosch, IHC, etc.) and match to the kit’s listed compatibility.
- Trigger type and maintenance: Decide between Hall Effect sensors or lobe sensors and understand how this affects maintenance and tolerances.
- Aesthetic and wiring: Some kits preserve stock distributor appearance; others upgrade wiring and module placement. Plan wiring routing in advance.
- Installation complexity: Some kits are plug-and-play; others require minor adapter wiring or sensor alignment. Consider your DIY comfort level.
- Environmental durability: Marine environments demand corrosion-resistant components and sealed electronics; look for durable housings and gasket protection.
- Engine performance goals: If your aim is smoother idle, better throttle response, or improved fuel economy, weigh the claims against your engine’s baseline condition.
FAQ
- What is an electronic ignition conversion kit? A kit replaces mechanical ignition points with a solid-state ignition module to improve reliability and timing accuracy while preserving the distributor’s appearance in most cases.
