Elevate the performance of your adventure crossover with the K&N High-Performance Air Filter. The HA-7521 is specifically designed for the updated 745cc parallel-twin engine, providing increased airflow and superior protection for the DCT-equipped Honda X-ADV.

Key Features

• Optimized for the "New Gen" 750: Engineered to provide up to 50% more airflow than traditional paper filters, allowing the engine to breathe freely and improving throttle response.

   

• Ultimate Engine Protection: Features multiple layers of oiled cotton gauze media, providing up to 99% filtration efficiency—essential for a bike designed to handle both urban commutes and gravel paths.

   

• Washable & Reusable: This is a permanent upgrade; the filter is designed to be the last one you'll ever buy for your X-ADV. Simply clean and re-oil as part of your regular maintenance.

• Precision Fit: Custom-engineered with a unique triangular profile to fit perfectly into the 2021+ factory airbox with an application-specific sealing bead.

   

• Extended Service Intervals: Designed to run for up to 50,000 miles (approx. 80,000 km) before cleaning is required under normal highway conditions.

Important Fitment Note

The HA-7521 is the correct part for the 2021 and newer X-ADV models. If you own an earlier version (2017–2020), you will likely need the HA-7417. Both filters offer K&N's signature performance, but the airbox design was updated for the Euro 5 generation bikes. By switching to K&N, you ensure your X-ADV maintains its peak torque and smooth DCT gear transitions by providing a consistent and unrestricted supply of clean air.
