Dude you are honestly wasting your money if you buy one of those grounding kits...why you ask??? Because you can make your own grounding kit and it will be a cheaper..

I have done this myself, just went to my local audio shop and got some 4 guage power wire (this was blue in color) and spent about $40 bucks cdn with all the connectors...

This was more than enough to make a whole ground kit..what I grounded was the following:

VTEC Solonoid
Throttle Body
intake manifold
upgrade oem block ground and tranny ground
upgrade battery ground

And thats it, much more less then buyin one, just do it yourself
