OKD Plasma Ground for the BMW 5-series (e60 and e39)
If you have a 2003 520i (e39), 2003 525i (e39), 2003 530i (e39), or 2004 and newer 530i (e60), then your BMW 5-series has the M54 engine. However, this engine came in more than one configuration. Your engine either has a single secondary ground to the engine, or it has dual secondary grounds to the engine. Please indicate which option your engine has when ordering.
The 540i (e60), 545i (e60), and 550i (e60) have V8 engines, which requires 2 OKD Plasma Ground amplifier units, therefore the price is higher.
The OKD Plasma Ground is connected at the ground side of the ignition coil and increases performance and engine efficiency by creating an ultra fast alternating current at the secondary spark discharge, this is called Coil Ground Tuning. Plasma Ground works perfectly together with all other OKD Plasma Ignition products (all sold on www.beastpower.com), and increases secondary spark discharge current. The 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-percent compatible with any late model OBD and engine control units.
