Here's my first aeromod on the XJ... finally found a front skid plate. Tomorrow I'll be putting on a full width belly skid too, and extending part of it to protect the muffler and cat. Then it will be very easy to add more bellypan.
I wish I could have gotten a good Scangauge comparison between the original air dam and the skid sans dam, but I messed up my calibration settings. It's a long way to a flat highway too.
