Product description
Get the maximum power out of your Honda CRF 250R / RX / RWE or CRF 450R / RX / RWE (2025 and newer) with the original Twin Air Airfilter FR – the number one choice of factory teams and serious motocross riders worldwide!
Twin Air has been renowned for its dual-stage foam technology for decades: a coarse outer layer traps sand, dust and mud, while the fine inner layer blocks even the tiniest particles. This delivers maximum airflow for faster throttle response, more power and improved throttle feel, without sacrificing engine protection.
Specially developed for the new generation CRF 250/450 models (2025+), this filter fits perfectly into the factory airbox. The thick, high-quality foam with patented construction and grease-free sealing ring provides a perfect seal and increased airflow. Ideal for sand tracks, muddy enduros, hard clay or intensive training sessions – this filter performs flawlessly everywhere and is easy to wash and reuse.
Whether you're racing competitively, training at the club level or pushing your CRF to its absolute limit: with a Twin Air filter, your engine stays cleaner, runs smoother and lasts longer. Thousands of top riders rely on Twin Air every day – now you can too!
