Okada Projects Plasma Direct Ignition Coils – Honda Civic Type R FL5 (2023+)

Okada Projects Plasma Direct is a high-performance direct ignition coil system that represents a major advancement in ignition technology. By integrating a high-power amplifier directly into each ignition coil, Plasma Direct dramatically improves combustion efficiency through increased secondary current and a unique multi-spark ignition strategy.

Designed and manufactured entirely in Japan, Plasma Direct delivers exceptional quality, reliability, and safety. It is fully OBD-II compliant and installs as a true direct bolt-on upgrade—no wiring modifications, splicing, or cutting required. Simply replace the factory ignition coils and you’re ready to go.

Key Features

• Multiple ignition sparks generated at ultra-fast microsecond intervals during a single combustion event
• Secondary current (amperage) increased to approximately double that of factory ignition coils
• Improved flame kernel growth for faster, more complete combustion
• Increased horsepower and torque across the entire RPM range
• Improved throttle response and smoother engine operation
• Potential reduction in fuel consumption due to more efficient combustion
• Direct replacement for OEM ignition coils with no vehicle modification required
• OBD-II compliant with built-in noise suppression to prevent ignition interference

Ignition Performance Explained

Plasma Direct produces a much higher ignition energy compared to factory coils by delivering significantly increased amperage during the initial spark discharge. This allows the spark to reach more air-fuel molecules, accelerating ignition and promoting stable flame propagation.

In addition to a stronger primary spark, Plasma Direct generates multiple ignition sparks in rapid succession. This multi-spark provision further enhances combustion stability, particularly under high load, high RPM, or forced-induction conditions.

Advanced internal noise filtering ensures consistent spark delivery while eliminating electrical interference that can cause ignition instability or ECU errors.

Installation & Compatibility

Plasma Direct ignition coils are vehicle-specific and engineered for precise OEM fitment. Installation is fully plug-and-play—remove the factory coils and install Plasma Direct units using the original mounting points and connectors.
