I have Bob's coolant filter on my X but installed it in a different place than his instructions stated. I put it behind the LF wheel mounted on the inside of the rocker panel and installed some ball valves from the hardware store to make changing the filter easier with out loosing too much coolant. I also made up a small shield under the filter to keep the tires from throwing things at it. There are some PICS in my signature.
