Thanks. Got the intake. Lmk the outcome please. It's just takes forever to shift. I have to shift on my own. 34" tires don't help I guess.

Regear to 4.88's and then go from there. 34's probably don't kill performance in a Rubicon, but if you've got anything less than 4.10 gears, you'll want to regear for larger tires. And 4.88's seem to be the go-to for 2012+ with 3.6L and automatic trans.

If it has a tow package, it's likely 3.73's. Otherwise it would probably be 3.21's.

Mine has the 4.10s and I thought it was an option

4.10s are only an option on Rubicon models (3.73s are standard). Otherwise, 3.21 gearing is standard and 3.73s are an option.

Before 2012, the Rubicon only came with 4.10's. There wasn't any other option. But when they mated the 3.6L with the new 5-speed auto, they also offered 3.73's for better highway feel and a little better fuel economy.

Take out the V6 and put in the 6.4L SRT8 392. Works much better.
