Fitment & Technical Details
Access the airbox compartment by removing the necessary side body panels or rear covers. Disconnect the rubber intake connecting boot from the carburetor, loosen any frame mounting bolts securing the old air cleaner case, and extract the unit from the chassis. Transfer any reusable rubber mounting grommets or hoses to the new 25K-14411-00 housing, position the case into the frame recess, secure the mounting hardware, attach and clamp the carburetor boot tightly, and reinstall the filter element and cover.
