Re: Will I need a new battery/alternator??
Probably, depending on your stock alternator and battery. What is the alt's rated amperage? Stock electrical usually can handle up to around 2k without big issues but depending on the age and strength of the electrical system you will probably need a big AGM under the hood and Big 3. I'd definitely do the Big 3 upgrade, though.
