pinakamaganda bumili sa electronic spare parts and accessories shops, kasi nandun lahat ng kakailanganin niyo.

btw eto ngapala ung mga kelangan:

gauge 8 wires (about 4 to 5 meters) = 32 php / meter

ring terminals = 5/ pc x 10 = 50 php

heat shrink tube = 15 php / pc

ung heat shrink tube optional yan. ginamit ko lang sa connection ng ring terminal at nung wire para malinis tingnan.

tools needed:

pliers = to splice the wire and to clamp the wires unto the ring terminals
socket wrench = to remove/ tighten bolts
heat gun = for the heat shrink tube ( kandila na lang ang ginamit ko)

give it 3-4 hours para sa project na to, and as sir yebo said don't expect added hp coz this is just an "improvement" of the stock engine grounding.
