Hiflofiltro Air Filter — HFA4601

OE-pattern replacement air filter for stock airboxes — same shape, same sealing surface, no rejetting or remap required.

• Pleated paper or foam media (matched to the OE design) housed in a moulded rubber frame for an airtight fit against the airbox.
• Direct drop-in replacement for the factory filter on the listed application; carb jetting and ECU fuel maps stay as-is.
• Built to the original equipment flow rate so peak power and fuel trim land where the factory put them.
• Designed and tested in the UK; ISO 9001 manufacturing.
• Service item — replace at the interval in your owner's manual or whenever the filter is visibly dirty or oil-soaked.
