Hiflofiltro HFF1015C Air Filter Cage | OEM Paper to Foam Conversion for Honda XR250R XR400R XR600R XR650L

OVERVIEW

The Hiflofiltro HFF1015C Air Filter Cage upgrades stock paper-element intake systems to a modern, reusable foam filter configuration for select Honda dual-sport models. Crafted from a high-strength molded polymer, this conversion cage locks cylindrical foam elements into place with precise alignment to ensure reliable performance across varied terrain. Designed to serve as a direct replacement for restrictive factory components, this adapter extends service life by enabling repeatable cleaning cycles instead of requiring frequent disposable element replacements.

ENGINEERING & PERFORMANCE

This adapter delivers stable, model-specific sizing that secures aftermarket foam elements completely within the engine airbox. Molded from impact-resistant plastic, the housing maintains tight tolerances around the flange to prevent unfiltered air bypass during intense vibration. The rigid internal geometry eliminates suction collapse common in thin paper cages, ensuring consistent airflow volume and optimized oxygen delivery to the cylinder throughout the ride session.

WHY RIDERS CHOOSE THIS

Riders install this air filter cage to transition older Honda XR models away from restrictive OEM paper designs toward cleaner, more efficient foam architectures. The durable construction absorbs suspension forces without flexing, keeping the reusable filter perfectly seated and sealed against potential debris ingestion. This modification enhances engine breathing and throttle response while driving down lifetime costs by allowing owners to wash and re-oil the same filter indefinitely.
