Could someone please post a picture of their engine if they have a nice grounding kit(preferably silver). I'm looking to getting one for my chrome silver Z tomorrow and i also have a polished intake so i figured silver or black would look the best.

 

there are a few pics at

does it really increase horsepower and torque?

 

nah, but it looks good!
