Great video like always bro!!!!

[@bbtechbbtech]

I am a bit unclear on one thing about the cable from Alternator to battery.....are you replacing it completely or also leaving the old one on?

[@VampyreX13]

You leave the old one in place.

Where did you get the intake cone filter shield?

[@VampyreX13]

I got it from amzn.to/3EempmD. It has a 2.75" outlet, so I had to custom print a 3" outlet to match my intake tube.

[@89gts]

Sorry I was meaning the wall shield that is separating the cone from the engine bay heat.

[@VampyreX13]

That is part of the K&N intake that I did a review for at kzbin.info/www/bejne/faO8nnWNqbChiZY.

I have a after market sub & speakers with 2 amps....Will doing a big 3 upgrade will work well stock alt & batt? Thinking about doing this before getting my battery & alt upgraded.

[@VampyreX13]

Yes. That's basically what I did.

[@andrewflores4981]

Why does that 2 Gauge looks as big as my supposed 1/0 Gauge. Currently have CCA wiring, wondering if you got OFC cable and if they're truly worth it?

[@VampyreX13]

The wire I used and have linked in the video description is pure copper and not coated aluminum. I'm not sure if you'll see much difference going from CCA to OFC at 1/0 gauge, but OFC is a better conductor.

How does this improve the car ?

[@VampyreX13]

It will improve the electrical charging system. This is something you want if you have amps and subs that have a high electrical draw (headlights dim when the bass hits).

[@JRcheesburger]

@@VampyreX13 what did you do with the original positive terminal on the battery? did you wrap tape around it or remove it?

[@VampyreX13]

@@JRcheesburger I left it in place.

[@pavelt8594]

Dang the alternator says it out of stock on Amazon and may never be back 😭

[@VampyreX13]

It was just in stock this morning. Message the seller and check if they will carry more.

[@popwarhomie]

I would not recommend amazon or ebay HO alternators. Most of the time their specs are extremely exaggerated, have very poor idle output, and cheap components. Stick to the name brands like DC power, Singer, Excessive Amperage, Ohio Gen, Mechman, AutoTech, CES, and Brand X. I have an Autotech 320 on my 2011 TC.

Is js alternators a good brand?

[@popwarhomie]

@@Eric-lu7gy I have heard good and bad from JS alternators. I will say they have a 1.6 out of 5 star rating on Yelp.
