I recently picked up a 2011 fx4 screw 3.5L with an aFe exhaust. I was researching cold air intakes but I found that May not be worthwhile. I've also found the gotts mod and tunes. I was looking simply to round out the exhaust with the intake side.

Would any of the above also smooth out the throttle response? Would you recommend the gotts mod anyways?

Referring to the gotts mod, is there an aftermarket snorkel yet or am I forced to jury rig something up?

 

Is it a 3.5 Ecoboost or a 3.7?

A tuner will be much more beneficial than an intake.
