The last piece of the puzzle was figuring out an intake and air filter for the engine. The stock Grand Cherokee stuff wouldn’t work and the TJ-style intake routes the filter over to the passenger side fender, where things were already pretty crowded on our Jeep. In the end, we opted to modify a cold-air intake system from AIRAID that was designed for a YJ with a 4.0L. The intake tube positions the filter on the driver side fender where we had more room, but it interfered with the power steering pump in its intended forward-facing position. We rotated the intake tube 90 degrees and pointed the filter at the firewall, then secured it with some of the brackets included with the intake kit.
