The secondary spark current on an Okada Project Direct Ignition reaches an improved 140mA and shows a wave pattern present in the multi spark oscillation, which improves combustion and increases ignition spark. Okada Projects representative Akira Sato states that the main importance of their Plasma Direct ignition is the change in current capacity while voltage is not important when looking to create an increase in energy spark. The oscilloscope shows the Okada Plasma Booster Direct goes from a range of 10 amps to -10 amps which are twice that of the factory unit. The secondary current also reaches 100mA, which is twice the twice milliamps of the factory 50mA current while also making an AC discharge, not possible on the factory setup.
Like most factory and aftermarket ignitions sold on the market today, a majority of them use a DC charge. Okada Projects has specially modified the coil pack to provide a DC to AC discharge which promotes larger oscillation and creates larger energy. Converting DC to AC creates more ions, which in scientific terms means larger current. Too good to be true? This simple, yet effective system also boasts a CARB certification for legal use on highways. How you like them apples?
Upgrading to the new plasma direct coil packs requires a quick swap of your factory 4G63 EVO coil packs otherwise known as a waste spark system. Replacing the stock units with the simple plug and play design minimizes any room for error with even the most novices of mechanics.
 Okada Plasma Direct Ignition...  Okada Plasma Direct Ignition coils build the booster into the coil pack on specific applications. For vehicles like the Mitsubishi Evo's, you cannot simply add a booster pack because the factory system uses a built-in ignitor in the coil. The Subaru EJ20 ignition setup uses a built-in igniter within the factory coilpacks. |  Subaru dyno results show promising...
