Okada Projects Plasma Ground BMW Z4 E85 M54

The Plasma Ground is connected to the ground side of the secondary end of the ignition coil. It increases performance and engine efficiency by creating an ultra-fast alternating current at the secondary spark discharge, called Coil Ground Tuning.

Plasma Ground works perfectly together with all other Okada Projects products and increases secondary spark discharge current.

Increase in secondary current is extremely important, since it creates a faster burn for high performance engines. The Plasma Ground is engineered to increase spark effectiveness on BMW engines, and is 100% compatible with any late model OBD and engine control units.


Note: ** M54('03- two secondary ground to the engine.
