One item we're sticklers for is a cold-air intake, especially for the 4.0L engine. We've found the K&N FIPK really wakes this engine up. On paper, they're usually good for 5 hp and at least 1 mpg, but in real life, it's a difference you can feel from the driver seat and that you'll notice at the fuel pump. The WJ FIPK took a leisurely 20 minutes to install.
