Is it just another aftermarket air intake system? Not this time. Banks Power recently unveiled its Sidewinder Turbo kit for 2005-to-2006 Jeep Wranglers equipped with the 4.0L I-6 engine. Horsepower and torque improvements are huge and greatly benefit street and trail-driving situations. Model year coverage will be expanded to include 1999.5-to-2004 Wranglers, as well. The hardware will be essentially identical to the current system, with a different electronic tuning to cooperate with the older-style ECU.
