hyper ground terminal kits
 

Are these worth the money to get? I see alot of cars have them but for the price versus the amount of horsepower you get out of them doesnt seem like alot. Plus having a bunch of large gauge wires splattered all over the engine bay doesnt look imo. So whats so special about these? any other benefits to having them other than getting the small 5-6 horses extra from them?

I have one in my car, and although the performance gains are minimal, I've noticed that the power distribution through out the car is a little more efficient. My lights dont dim anymore with the stereo pumping or A/C on and over all...the car just seems to respond better since I put it in.

just make your own

or buy a generic ebay kit

DON'T buy the expensive kit, it's no better than running some 4ga wires to important locations for the charging and ground system. Upgrading the alternator to battery, battery to chassis, and chassis to engine cables to 4ga will make a big impact on how well electricity can flow through your electrical system.

Also, unless your car has issues, you will get exactly 0hp from this. We back to back dyno tested a Spectra5 and got the exact same hp numbers both times.
