To get to the cabin air filter on an XK8 or XKR, you have to do the following steps (I know these steps sound ridiculous...as in many cars there is just a simple cover in the engine compartment... but...): The air filter is under the black plastic cowl or plenum that is just under the windshield wiper blade connectors. To get to that, you must 1. carefully lift off the plastic covers that reveal screw heads. Remove the screws. 2. lift off the plastic covers that are on the top of each windshield wiper connector - under the cover you will then see a nut or bolt that has to be unscrewed. 3. Using a small puller (the puller that lifts off battery terminals works for this) lift off each windshield wiper and disconnect the rubber hose from each. 3. lift the car's front hood, and remove the plastic cowling (you also have to lift the side rubber runners and a rubber strap from each side that holds up the rubber drain hoses). Once you remove that plastic cowling, you will see the air filter plenum at the back of the engine area. The air filter should come vertically out of that. (This air filter does not exist on my 2000 and earlier editions...I am not sure what year Jaguar installed them.) Full instructions are on the Jaguar JTIS CD which you should obtain...look online for that.
