I was looking at this part

http://www.okadaprojects.com/usa/products_ground.htm

The 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 Okada Projects Plasma Ignition parts 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-percent compatible with any late model OBD and engine control units.

What does everyone think? will this increase performance?

Will it give me 400hp JKidding about the 400, will it give me 350?

 

I think it may be good for only 349 hp at best .
Or a good way to lighten your wallet by adding some bling.
If all your connections are good with no corrosion, if I remember right, electrons travel at close to the speed of light. That would be hard to beat unless you use fiber optics. Anyway, good luck.
