This kit is made to upgrade your factory positive and negative wires to increase your cars electrical system. By increasing the size of the wire, it will raise the alternators output voltage which will improve everythings performance that uses the 12 volt system. For example, ignition, steering, stereo, headlights, etc. When we installed this on our shop Sonic it bumped the voltage .3, other people have reported more. We are not tricking the alternator to put out more voltage, we are just allowing the full voltage from the voltage regulator to make it to the fuse panel and battery. Whatever output voltage you have must have a better ground as well, so we include 2 upgraded ground wires as well.

The Cruze comes with 1 less wire than the Sonic.

This Product Provides The Power!!!

I'm no mechanical expert and I even had my friend install this Big 4 Power Wire Kit upgrade for me, but the product is a must buy. My car's electrical system seems to be more responsive and my cabin lights/dashboard lights don't flicker anymore. I always trust ZZP products and if you have a Chevy Sonic like me, buy their mods. 5 stars!

Cruze ZZP big “3” wire upgrade

The high strand count of the wire makes them super flexible. The insulation of the wires after a week seems ok, time will tell. The picture for installing the battery ground and cylinder head ground is reversed!!! The longer wire with the larger stud eyelet on one end is for the cylinder head. The heat shrink tubing on the terminations is junk IMO!!! Do yourself a favor and buy some top of line self sealing 3:1 or 2:1 heat shrink at Fry’s and remove the supplied heat shrink and install what should have been from the beginning!!! The supplied heat shrink split off on the cylinder head end ground wire within 10 miles. Fortunately, I keep a kit of heat shrink handy. This will be very helpful with the battery ground terminal which will invariably corrode over time!!! The lengths of wire are sufficient!

Didnt notice anything considering I have no amps or extra electrical items. I always do big 3 upgrade on all my cars. Best thing to do regardless, plus the wires add color :)

Review title

Great kit, easy to read instructions easy to connect if you have eyes. Fixed my low idle issues and the engine feels a lot smoother through the rev range.
