Alternator Voltage Booster

I've noticed the lighter are much brighter. 20 second install. Works good, good build quality, fast shipping.

It really works

I'm always sceptical about parts like these. I don't have a manual volt gauge but the headlights are briter, windows go up faster and in winter the rear defrost seems to work alot faster. For the $$ in my opinion it's a good buy. While your at it get the wire from fuse box straight to allternator. Thanks ZZP
