AIRAID Cold Air Intake System for 91-95 Jeep Wrangler YJ with 4.0L I6 Engine

AIRAID Premium Filter Company has found a way to unleash some of the 4.0-liter's hidden horsepower and torque with the development of a new Cold Air Intake system for the 91-95 Jeep Wrangler YJ. AIRAID's Cool Air Dam system for the 4.0-liter YJ features a full-length intake tube and a computer- designed Cool Air Dam, which is designed to isolate engine heat away from the air inlet and take advantage of the dense, cool air from outside of the engine bay. At the heart of the system is AIRAID's Premium SynthaFlow™ filter that allows for both maximum air flow and superior filtration, down to 2 microns. The system not only improves air flow by 42 percent over the stock air box, but also dramatically improves throttle response and both horsepower and torque across the RPM range.
