Generac 0J8478S Air Filters – 2 Pack

Description

Keep your compatible air-cooled standby generator operating with clean intake airflow using this two-pack of genuine Generac 0J8478S Air Filters. Each OEM filter captures dirt, dust, and other airborne contaminants before they can enter the engine.

These genuine Generac OEM air filters are designed for select air-cooled home standby generators. Before you order, please check your generator’s complete model and serial number to confirm compatibility.

Why Replace Your Generac 0J8478S Air Filters?

The air filter is a small part, but it protects one of the most important parts of your generator: the engine. A clogged or damaged air filter can restrict airflow and allow contaminants to reach the engine.

Replacing clogged or damaged air filters can help support efficient combustion, reduce engine strain, and maintain dependable generator operation. Having two filters also gives you a convenient spare for future scheduled maintenance, so the part is ready when you need it.
