In high power Subarus, efficiently igniting the highly compressed fuel and air mixture can start to get tricky. Okada Projects has solved this problem with their high energy Plasma Direct Coil Packs. They will store and release more energy which will help your spark plugs ignite the mixture to get a complete burn in the cylinder. They are engineered with high power and high RPMs in mind and can store and discharge their energy quickly even in a high revving engine. If you are building a high power FA20 engine, look no further than the Okada Coil Packs to ensure you are extracting the maximum power from your engine.
