The Sinister Diesel windshield washer cap for 2017+ Ford Powerstroke trucks provides a finished replacement cap for the washer fluid reservoir. Designed to fit the 2017 and newer Powerstroke engine bay layout, it offers a durable, vehicle-specific aesthetic upgrade that installs in place of the factory cap and preserves normal reservoir access and operation.
