The Wacker Neuson Air Filter Secondary G320 is a genuine OEM secondary air filter designed for the G320 portable generator series. This is the factory-specified secondary filter element, engineered to work in tandem with the primary filter to catch fine particulate that bypasses the first stage — keeping the engine intake clean across demanding jobsite conditions. It fits a wide range of G320 configurations including Standard, Cold Weather, Custom, and Mobile variants across T4, T4i, and Tier 4 Final emission ratings. Sourcing a genuine Wacker Neuson part ensures the filter element meets the exact dimensional and filtration specifications the G320 engine was designed around.
Key Features
- Two-Stage Filtration Integrity — Engineered to the correct media density and element dimensions for the G320 air intake system, ensuring the secondary stage performs as intended alongside the primary filter.
- Genuine OEM Part — Supplied by Wacker Neuson as original equipment, matching the exact specification used in G320 generator production — no guesswork on fit or filtration rating.
- Broad G320 Coverage — Confirmed fitment across Standard, Cold Weather, Custom, and Mobile G320 configurations in T4, T4i, and Tier 4 Final emission tiers, including Transport Canada-certified units.
- Engine Protection When It Counts — A clogged or missing secondary element allows fine dust and debris to reach the engine intake, accelerating wear on internal components and risking unplanned downtime on power-critical applications.
- Emission Compliance Support — Using the correct OEM filter element in Tier 4 Final-rated machines helps maintain the engine's designed air-fuel ratio, supporting continued compliance with emissions standards.
The secondary air filter sits behind the primary filter element in the G320's air intake system and acts as the final barrier between the outside environment and the engine's combustion chamber. While the primary filter handles the bulk of airborne dust and debris, the secondary element catches the fine particulate that passes through — protecting sensitive engine components from abrasive wear. When the secondary filter becomes blocked or degraded, airflow restriction increases, engine performance drops, and fuel efficiency suffers; in severe cases, contaminated air can reach the engine and cause premature wear or damage to pistons, rings, and cylinder walls.
