Always verify fitment against your specific Yamaha model and year using the manufacturer's application guide before purchasing.
Replace the air filter at the service intervals specified in your motorcycle's owner's manual.
Before installation, inspect the air box and intake tract for debris, cracks or deteriorated seals.
Handle the filter element with clean, dry hands to avoid contaminating the filter media with oils or grit.
Ensure the filter seats squarely and the air box cover is fully secured before starting the engine — even a small air leak bypasses filtration.
Do not attempt to clean or re-oil this element unless the manufacturer's documentation explicitly states it is washable; HFA-series elements are typically disposable.
Dispose of the used filter element responsibly in accordance with local regulations.
