At Banks we have long known the best way to maximize power is by feeding your engine cool, dense, oxygen rich air. Now we have brought that density focus to our already potent Sidewinder Turbo for Jeeps. Designed to increase the responsiveness of the Banks Sidewinder Turbo System for 4.0L Jeeps, the intercooler kit provides smooth drivability and linear throttle response both on- and off-road.

The intercooler allows for steady power output even under extreme ambient temperatures. Cooler charge air temperatures allow for more efficient spark timing whether you're cruising, crawling, or running full-throttle.
