Regitar USA RME014 Distributor Cap for GM V8 Thunderbolt IV/V HEI Ignition

The Regitar USA RME014 is a premium distributor cap designed specifically for marinized GM V8 engines equipped with Thunderbolt IV and V HEI (High Energy Ignition) systems. This critical ignition component distributes high voltage spark from the coil to each cylinder at precisely the right time, ensuring reliable engine performance in demanding marine environments.

Key Features:

• Engineered for GM V8 engines (5.0L, 5.7L, 7.4L, 8.2L) with Thunderbolt IV and V ignition systems
• Compatible with HEI (High Energy Ignition) systems only - not for point ignition systems
• High-dielectric strength construction resists electrical breakdown and moisture intrusion
• Brass terminals provide superior conductivity and corrosion resistance
• Designed specifically for Mercury/MerCruiser marine applications
• Direct replacement for OEM Mercury part numbers 815407A2, 805759Q3, and others

Regular inspection and replacement of the distributor cap is essential for maintaining peak engine performance. As this component ages, electrical insulation degrades, leading to misfires, rough running, and difficult starting. The RME014 delivers reliable ignition performance for inboard marine engines, making it an ideal choice for routine maintenance and tune-ups.

Engine Compatibility: Mercury/MerCruiser GM V8 engines with Thunderbolt IV and V HEI ignition systems from the early 1980s through early 2000s.
