TWIN AIR — Pre-filter (ref. 150233DC)

Designed for heavy and abrasive terrain outings, this Twin Air pre-filter is installed as a complement to the original filter to better protect your engine from dust and sand. Its airy foam structure, pre-oiled at the factory, promotes particle retention while maintaining the airflow necessary for proper intake function.

• Enhanced protection: foam wrap to capture fine dust and sand grains during cross and enduro outings.
• Less maintenance: the oiled foam reduces the frequency of cleanings compared to a dry pre-filter.
• Simple installation: mounts as an overlay on the original filter for additional protection without major modifications.

Ideal for riders who frequently encounter dusty or sandy trails, this pre-filter extends the lifespan of the main filter and reduces the risk of premature clogging. Compatible with cross and enduro practices, it is particularly suitable for recent 450 cc models such as HONDA CRF 450 RX ENDURO (PE07), CRF 450 RWE, and CRF 450 R (2026).

To maintain optimal filtration, check and clean the foam according to the aggressiveness of your outings: regular maintenance is essential to preserve engine performance and reliability during long riding days.
