What Is Plasma Direct(High-power ignition coil)?

A revolution in ignition technology! Plasma Direct is the most advanced direct ignition system which integrally incorporates a high power amplifier into an ignition coil, using our own technology to enhance combustion efficiency by drastically increasing the secondary current and providing multiple sparks in a unique way. All our products are made in Japan with high quality, reliability and safety unrivaled in the industry. Plasma Direct is also OBD II (On-Board-Diagnostics) compliant. Installation is easy. Direct bolt-in to the engine, no splicing or cutting into stock wiring, simply replace the stock ignition coils with our Plasma Directs and ready to go!

Product Features

Plasma Direct lets a spark ignite more than three times at ultrafast speeds during one combustion process and also supercharges the sparks up to the highest RPM without damaging ignition plugs.

The secondary current (amperage) can be approximately double that of stock ignition coils, which allows the spark to reach many more molecules, thereby accelerating the ignition and combustion process.

Horsepower and torque are increased throughout the entire RPM range, so this upgrade will also reduce fuel consumption. Even engines with legendary smoothness will be further refined with the Plasma Direct upgrade.

Plasma Direct is made to a specific application. Please check the Application Chart below to find the correct model for your vehicle.
