I ordered the week prior to christmas and it arrived the day AA said it would. I've had the catalyst on my '03 Liberty limited automatic for about 3 weeks and it does make a difference, both in fuel economy and general performance. I live in avon, CO and have both the high altitude and cold weather to contend with during winter driving, so I averaged around 12 mpg in town and 20 mpg on I-70 prior to the FFC installation. I'm a very conservative driver as well, so I pretty much hated my mpg's. Each week my mpg's have steadly improved. I'm now getting around 15mpg in town, and while highway mpgs have only improved about 1 mpg, the auto tranny doesn't "hunt" for lower gears as often to maintain speed while climbing Vail pass. Plus I've been running 85 octane in it, specs so to run 89 or higher so it must add something. The only reason I dont give it excellent marks is becuase I couldn't install it myself w/o the proper tool to disconnect the fuel line from the rail. Still, it only cost $40 to install at local shop, so no biggy.
