Big 3 must have
Alex✓ Verified Purchase•September 14, 2023
This was great for the Big 3. Wires look great. And the wires where long enough. It was easy to install.
Worth it.
Amazon Customer✓ Verified Purchase•September 3, 2023
Worth every penny. It eliminated all my engine whine and hissing from my amps and not to mention my stock alternator charges like crazy now
Great upgrade

Cars from certain (Most) manufactures cut back on cost by placing
the "bear minimum" parts on vehicles to save cash.
Including the 3 main electrical wires.
Alternator to positive battery terminal wire,
negative battery terminal to ground engine bay chassis wire, and
engine block ground wire to engine bay chassis post.
Those "factory" wires when you first get the car are small! Have you seen them!?
Their as small as spaghetti!

Best budget deal out there.

For $25 shipped this is possibly the best automotive electrical upgrade available. As it is CCA wire and not OFC wire I recommend it for cheaper vehicles/budget installs. Spend $10 more for the OFC kit if you want it to last 5+ years. But for what I paid, this absolutely severely upgraded my stock electrical system. Windows roll up and down faster, sunroof opens and closes faster, and my sound system works well all the time without my voltage dropping.
