The K&N HD-1208 is a replacement panel-style air filter for the 74 CI Harley-Davidson XR1200 and XR1200X Sportster. It uses layered cotton gauze media with a pleated design and is pre-oiled and washable. The manufacturer says it is designed to increase horsepower and torque while maintaining engine protection, and it includes an application-specific base seal.
The case for this filter over a disposable paper element is lifecycle cost and airflow. The manufacturer describes it as reusable and designed for long service intervals, so you clean and re-oil it instead of replacing it. Expect a modest change rather than a dramatic gain: one owner on a user forum who fitted a K&N to an XR1200 reported little noticeable difference. Fitment is listed as the XR1200 and XR1200X for 2008 through 2012, but year splits vary between references, so confirm your model year before ordering. Owners on user forums also caution against over-oiling, since excess oil can migrate into the intake and foul sensors. Long-tail searches this part targets include K&N HD-1208 XR1200 air filter, XR1200X Sportster 74 CI reusable air filter, and Harley-Davidson 2937708 cross-reference.
The manufacturer lists the XR1200 and XR1200X Sportster in the 2008 to 2012 range. Year splits differ between references, so confirm fitment for your specific model year with the manufacturer before ordering.
The manufacturer describes it as washable, reusable, and pre-oiled, and the package includes a 1 oz tube of K&N sealing grease. Owners on user forums advise against over-oiling because excess oil can foul sensors.
The manufacturer says the design is intended to increase horsepower and torque but does not publish a power figure for this part. One owner on a user forum who fitted a K&N to an XR1200 reported little noticeable difference, so expect a modest change.
This is a filter swap into the stock airbox, so it does not require modifying the intake. The manufacturer publishes an installation instruction sheet for the HD-1208, and a video walkthrough shows the procedure on 2008 to 2012 XR1200 models. Follow the sheet closely when seating the base seal. If you clean the element, let it dry fully and re-oil lightly before reinstalling, since over-oiling is a common concern among owners on user forums.
