I had on my old 2012 Rubicon a Dale Banks CAI and Exhaust. I dyno'd it and the best runs produced 205 HP and 214 Torque. The dyno sheet is attached. This was with the factory tune. The mods do increase HP and Torque at the expense of the risk of water problems.

I hear Snorkels are the only true CAI setups however there are videos out there showing how they decrease HP up to 30% when used with a supercharger. Besides, many snorkel manufacturers claim 0 performance gains and ill take them at their word.

 

To the OP I installed Red Rock intake or whatever name that is from ET for less than $175. Sounds good and feels like it pulls a but more when hammering down in traffic.
