Big 4 Power Wire Kit


9 reviews

This variant is currently sold out

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.

2012 Cruze 3 Wire set

No problems with install. The wire lengths on my Cruze were appropriate and with a bit of care during routing you won't even know they are on the car.

High quality

Stainless steel hardware Thick but still flexible cables Quality heat shrink (unlike another reviewer in this section. ZZP must have listened to the feedback and improved the heat shrink)

Does what it does, exactly how it should

Worked out great. Fixed a bunch of little annoying things. Too much to list. The alternator span was a little short, but maybe I am a ***** and routed it wrong. It works fine. Just barely made it on my 2015 Cruze LT, and that is the changeover year with random bespoke things, so that could be it too. having some colour options would be dope. Maybe even a matching engine hardware dressup kit? I'd buy **** out of that. Lol

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!
