Superchips superchips trail jammer ext system for 99-01 Jeep Cherokee XJ with 4.0L

The Flashpaq programmer optimizes Jeep engine settings to maximize performance with the throttle body and CAI installed. Power, fuel economy and towing tunes are included in Flashpaq. Automatic transmission shift optimization is also available and users can calibrate for tire sizes from 22.5" & 42" (if properly equipped). Superchips' 62mm bore high-flow throttle body accommodates increased airflow and improves overall drivability. Fresh air enters through the Trail Jammer EXT's cold-air intake, which flows 97% better than stock: 195 CFM compared to the OE 99 CFM. The system's oil-impregnated, cotton-mesh filter traps dirt and debris and is washable/reusable.
