Why choose the OEM Aprilia filter instead of an aftermarket option?

Selecting the original filter helps avoid fitment issues, ensures proper oil pressure and supports warranty requirements when applicable.

• Exact fit with factory housings and gaskets
• Filtration media matched to Aprilia specifications
• Imported and labeled with Aprilia OEM numbers for traceability
• Recommended during warranty coverage to maintain compliance

How do I install and replace this oil filter properly?

Installation follows the same procedure as the stock filter: drain oil, remove the old filter, install the new unit with any specified seals, and refill to the correct level. Use the torque values and oil type listed in your owner’s manual to avoid leaks or damage. If you’re not comfortable performing the service, have an authorized Aprilia shop fit the filter.

• Drain engine oil before removing the old filter
• Inspect and replace crush washers or O-rings as required
• Tighten to factory torque and check for leaks after start-up
• Record date and mileage for service history
