Does this include a complete intake kit?

No. The package contains one replacement air filter, not an intake tube, airbox or mass-airflow sensor.

Does the filter need oil?

No. This is dry synthetic media. Adding filter oil is not part of its maintenance procedure.

Will it fit an aftermarket intake?

Do not assume so. An aftermarket system can use a different flange, height, sealing surface or filter part number. Match that systems exact replacement-filter reference.

Can it be washed and reused?

Yes. Follow the correct procedure for the media and allow the filter to dry completely before reinstalling it.

Does the filter guarantee a power or mileage increase?

No fixed performance gain is promised. The filter does not replace engine repairs, calibration work or maintenance of other intake components.

What should be checked during installation?

The manufacturer requires the orientation arrows on the filter to face the airbox. Fully seat the element in its tray and resecure the housing without forcing the seal.
