Second battery on passenger side help

.

 

hmm, URD would be your best bet because the air filter goes through the firewall behind the grill. The AFE boxed intake and the K&N/AEM cheepo heat shield style wouldn't work too well but u may have something with URD.

 

Thats interesting, I am too looking at second battery setup. I was thinking about just shortening intake tube and relocating ABS onto the firewall with home made bracket. Both would give plenty of space for second big battery

 

what's the 2nd battery for?

 

Extra electricity : Winch, Fridge for camping, TV, lights on the back
This way you can have things running all night and not worry about starting truck in the morning.

 

Would it really give you that muuch power?? That's awesome, I may have to look in to this
