The K&N PL-1920 is a panel-style replacement for the stock Polaris Slingshot air filter, built from multiple layers of woven cotton gauze in a pleated design. The manufacturer says the base seal and sealing bead are application-specific, so the filter is meant to sit in the factory airbox without modification. Because it is washable, reusable, and pre-oiled, you can clean and re-oil it at service intervals instead of replacing a paper element each time. The manufacturer claims increased horsepower and torque, but it does not publish a figure for this application, so treat any gain as unquantified. Other intake components, such as the housing and tubing, can also limit airflow.
Fitment is the first thing to confirm. This listing is titled for 2020–2021 Slingshot models, while K&N's category pages list the same part number for later model years and several trims, including R, S, SL, SLR, Grand Touring, and AutoDrive versions. Match the part to your exact year and trim before ordering. For Slingshot owners searching for a washable Slingshot panel air filter, a PL-1920 cotton gauze replacement, or a stock airbox intake upgrade, this is a direct-fit option that keeps the factory setup intact.

Yes. The manufacturer describes it as washable, reusable, and pre-oiled, with a re-oiling amount of 2.01 oz (59 ml).
The manufacturer states that K&N replacement air filters are emissions legal in the United States. It also notes that intake systems are regulated parts and not all of them can be used in California on pollution-controlled vehicles, so confirm compliance for your specific vehicle.
Polaris's service procedure for 2020-and-newer Slingshots is a straightforward airbox job. Park on a level surface, set the parking brake, and open the hood. Clean debris from the airbox area first, then unhook the five metal clamps and lift the airbox cover, taking care not to damage the airbox connector. Polaris warns that dirt entering the intake tube can cause severe engine damage, so clean the inside of the airbox thoroughly before installing the new filter. Install it with the word "UP" visible on the filter, reseat the cover, and secure all five clamps. Close the hood and confirm all four latch points are engaged. Wear safety glasses and nitrile gloves throughout. Polaris also advises against cleaning its stock filter, which is a separate matter from the washable K&N element. No specialty tools are called out in the procedure.
