FAQs

How often should I change this air filter?

It is recommended to replace the filter every season, or every 25 hours of use, whichever comes first.

Can I clean this filter with compressed air?

Light cleaning may be possible, but if the media is discolored or damaged, it must be replaced to prevent engine harm.

Does this fit all Cobra lawnmowers?

No, this is specific to the DG600 and DG600V engines used on models like the M51SPC.

Why is the filter oily?

If you notice heavy oil saturation on the filter, it may indicate that your engine is overfilled with oil or the breather system requires inspection.

Is this a genuine part?

Yes, part number 25100131601 is the official replacement component for the specified Cobra engine models.

Troubleshooting

Engine still running roughly after installation

Ensure the air filter housing is tightly sealed and no debris was pushed into the intake during installation.

Verify that the filter is properly aligned and fully seated within its plastic frame.

Setup, Compatibility & Care

To install this filter, first locate the air filter housing on the side of your DG600 or DG600V engine. Remove the housing cover—typically secured by a knob or clips—and extract the old, dirty filter. Wipe the inside of the housing clean with a dry cloth, being careful not to let debris fall into the intake port. Insert the new 25100131601 filter, ensuring it is seated perfectly to create an airtight seal. Replace the cover. For maintenance, check the filter every 25 hours of operation, or more frequently if you are mowing in exceptionally dry or sandy environments. Do not attempt to wash or reuse a paper-element filter; replace it whenever it becomes discolored or clogged.
