Air Filter
| Brand | Part Number | Markets | Notes | Buy |
|---|---|---|---|---|
| VARIOUS MFR | PA3192 | 🇺🇸 US 🇨🇦 CA | View on Amazon |
This table covers the engine air filters in the intake box. Typical signs include hesitation, a dirty film in the air box, or a filter so packed it collapses. Seat the new filter in the box so unfiltered air cannot bypass the seal.

| Brand | Part Number | Markets | Notes | Buy |
|---|---|---|---|---|
| VARIOUS MFR | PF6566 | 🇺🇸 US 🇨🇦 CA | View on Amazon |
This table covers the fuel filters in the line or at the tank. Typical signs include restricted flow — long cranking, weak airflow, or dirty fluid after a short interval. Seat the new filter so it cannot bypass, and use the grade the notes call for.
