EVE310-136 / 310-136 - Application Notes AIRAID® is proud to announce the release of our newest QuickFit™ Series intake system for the popular 1991- 2001 JEEP Cherokee (XJ) with the 4.0L engine. This bolt-on system comes complete with all the necessary hardware and installs in just minutes. AIRAID’s QuickFit Series Intakes utilize the factory air intake box, taking advantage of the dense cool air flow that the factory location provides. At the heart of the system is AIRAID’s Premium SynthaFlow™ series High-Flow Filter that increases air flow by 104.4% over the stock air filter assembly. The increased flow produces a noticeable increase in throttle response and increased power.
