Generac Quantum Air Filter Cartridge OEM #116621

Keep your Generac-powered equipment’s Briggs & Stratton Quantum engine running cleanly and efficiently with this Genuine OEM Quantum Air Filter Cartridge. A genuine Generac OEM part designed for long-term performance and compatibility with Generac systems, this authentic cartridge-style replacement air filter is precision-manufactured to exact factory specifications — delivering the correct filtration efficiency, airflow characteristics, and dimensional fit required to protect the Briggs & Stratton Quantum HD engine from damaging dirt, dust, and debris ingestion.

Important Brand Note:
Part #116621 was originally a DR Power part and is now supplied under the Generac brand following Generac’s acquisition of DR Power — making this the current factory-authorized replacement filter for both Generac and original DR Power equipment applications that specify this part number.

Why the Air Filter Cartridge Is Critical:
The air filter is the engine’s first and most important line of defense against airborne contaminants. The air filter provides the first line of defense against the destructive effects of dirt ingestion into the engine’s combustion system. On Briggs & Stratton Quantum HD engines used in Generac outdoor power equipment, a clogged or degraded air filter restricts airflow to the carburetor, causing hard starting, rough running, loss of power, increased fuel consumption, and elevated engine operating temperatures. A failed filter allows fine dirt particles to bypass filtration entirely — scoring cylinder walls, accelerating piston ring wear, and dramatically reducing engine service life. To maximize engine life, meet original equipment specs, and provide full warranty coverage, always use genuine parts.

Signs Your Air Filter Cartridge Needs Replacement:

• Engine is difficult to start or runs rough at idle
• Noticeable loss of power or reduced equipment performance
• Increased fuel consumption compared to normal operation
• Visible dirt, discoloration, or debris loading on the filter element
• Filter element compressed, torn, or structurally compromised
• Scheduled maintenance interval reached per operator’s manual recommendation
• Equipment stored over winter — replace the filter at the start of each season

Key Features:

• Genuine Generac OEM part — not aftermarket or generic
• Designed for long-term performance and compatibility with Generac systems
• Cartridge-style filter element engineered for the Briggs & Stratton Quantum HD engine series
• Factory-correct filtration efficiency and airflow characteristics for proper engine breathing

Compatibility:
This air filter cartridge is designed for select Generac and DR Power outdoor power equipment equipped with Briggs & Stratton Quantum HD engines. Always confirm fitment using your equipment model and serial number — found on a label on the engine or equipment frame — and cross-reference against your unit’s operator’s manual or Illustrated Parts List (IPL) before ordering. Always refer to your owner’s manual for the correct part number for your specific engine spec.
