Race tested and track proven technology for your car. Factory grounding points are inadequate for even mildly tuned vehicles. Taylor's grounding kits provide better flow for your electrical system, resulting in even, consistent voltage. This results in a better spark, burning fuel more efficiently. You'll experience crisper throttle, more even idle, brighter lights and an improvement in your stereo's performance. Many owners experience up to 5HP and an increase in fuel mileage (when driving under normal conditions of course). Kit includes head to block grounding straps, battery to starter and battery to ground/ block cables with heat shrink sleeve tubing and all the necessary mounting hardware.
