These guys do a bunch of dyno runs comparing between stock, CAI and no air filter for a 4.0L TJ

results:

code :Condition Avg HP Avg TQ 3SD HP 3SD TQ
stock 140.92 177.49 2.79 3.68
No Horn 142.12 176.69 3.73 6.06
Tire pressure 146.96 181.20 2.07 10.54
No Intake 151.72 183.12 2.46 5.54
Cowl Intake 149.32 185.71 5.57 5.75

Pulls 1-5 were done on the stock intake setup
Pulls 6-8 were done after removing the stock “horn” on the airbox
Pulls 9-12 were done after increasing the tire pressure from 25psi to 55 psi. This was done to try to minimize the wavy torque curves.
Pulls 13-14 were done with no intake at all, just an open throttle body with the IAT sensor duct taped 2″ above it.
Pulls 15-18 were done with the aftermarket intake.
