Description

Keep your compatible standby generator ready for scheduled maintenance with the UGP 0868539E 0J8478S filter kit. This aftermarket air- and oil-filter set is designed for select 14–22 kW air-cooled generators manufactured primarily in 2013 and later, equipped with compatible V-Twin 990cc or 999cc engines. It combines an air filter and a high-capacity oil filter to help support clean airflow and effective engine lubrication.

Before purchasing, confirm that your generator requires the specified air- and oil-filter part numbers. Compatibility depends on the complete generator model, serial number, engine displacement, and production date.

UGP 0868539E 0J8478S Filter Kit: What’s Included?

This one-pack generator filter kit contains the following components:

• 1 × UGP air filter: Replaces Generac 0J8478 and 0J8478S.

The kit provides both specified filters in a single package for convenient scheduled maintenance. Engine oil is not included, so purchase the correct oil separately if your maintenance procedure requires it.

Key Features of This Generator Filter Kit

Air Filter for Clean Airflow

The included air filter replaces Generac 0J8478 and 0J8478S. It helps prevent dirt and debris from entering the engine, supporting clean airflow during normal operation.

Using the correct replacement air filter is an important part of routine generator maintenance. Always verify the required part number and fitment for your particular generator before installation.

High-Capacity UGP Oil Filter

The UGP 0868539E oil filter replaces Generac 070185E and 070185ES. Its high-capacity 90mm design offers approximately 30% more oil-filter capacity than a standard 75mm filter.

The oil filter helps capture contaminants circulating through the engine oil. This supports effective engine lubrication when the filter is correctly matched to the generator and maintained according to the manufacturer’s recommendations.

The stated capacity comparison refers to the oil-filter design. It does not mean that the generator requires 30% more engine oil.

Designed for Select Air-Cooled Standby Generators

This aftermarket filter set is designed for select 14–22 kW air-cooled standby generators with compatible V-Twin 990cc or 999cc engines. The intended applications are primarily generator models manufactured in 2013 and later.

Model year and output range alone do not guarantee compatibility. Always check the complete model and serial numbers, engine displacement, production date, and owner’s manual before ordering.

Installation and Maintenance Considerations

Before installing the replacement filters, consult your generator’s owner’s manual and follow the manufacturer’s maintenance instructions.

1. Identify the complete generator model and serial number.
2. Confirm the engine displacement and production date.
3. Check that the required air filter is Generac 0J8478 or 0J8478S compatible.
4. Check that the required oil filter is Generac 070185E or 070185ES compatible.
5. Follow the manufacturer’s instructions for filter replacement and any required engine-oil service.
6. Check the manual for the correct engine oil specification and quantity, as oil is not included in this kit.

Do not assume that a filter fits solely because the generator has a 14–22 kW output rating or a 990cc or 999cc engine. If any compatibility details are unclear, verify them with the generator manufacturer or a qualified service professional before ordering.
