Not exactly. The air is metered and controlled electronically via the throttle body. The ECU is only going to allow so much volume air in, regardless of what your right foot is doing to the peddle. You can witness this real time with something like TorquePro and a OBDII dongle. When you floor it you'll rarely see throttle position go above 70% before it comes down to about 50%.Yes and no. More air in is OK if you can get it out, so you'd need to make sure the intake plenum matches as mentioned already, and a straight free flowing exhaust from the engine to tail pipe like the Ram as well. The Jeeps use a weird curly-Q bend in the exhaust.
But yeah if you did a big wide open air intake (which makes you vulnerable to water ingestion so you need to be careful) and a big wide open exhaust you'd definitely pick up power with the JL/JT version of the P-star.
The only way to get past that is tuning.
The longer runners in the Ram and Charger plenums increase velocity inside the plenum. Allows the air to stack up behind the valves. Same amount of metered air in, it's just moving faster. All top end gains.
