Hyper Ground System wires from XS Engineering are the true JDM ground wires, for Toyotas, Nissans, and Mitsubishi, and have dyno proof of horsepower increase:
.........1.03hp on an S2000.....but....7.09hp on a RX-7 and 6.23hp on a Maxima.
They're $100 for 4cyl though... Contact XS Engineering
www.xs-engineering.com or call 714-698-8300...i figure for the HP they're probably a better deal than whatever eGay has.
I sounded like an advertisement
