UGP-Generac Combo 6485 Maintenance Kit for 16–26 kW Air-Cooled Generators

Description

Service Your Generac Air-Cooled Standby Generator

The UGP-Generac Combo 6485 Maintenance Kit brings together the components most commonly replaced during scheduled maintenance on select 16–26kW Generac air-cooled home standby generators. It’s a mixed-component kit: a UGP-brand replacement air filter paired with a genuine Generac oil filter and Champion spark plugs (or equivalent) — not an all-genuine-Generac kit.

Replacing the air filter, oil filter, and spark plugs at the intervals recommended in your generator’s owner’s manual helps maintain clean airflow into the engine, effective oil filtration, and dependable ignition — the core service items behind consistent standby generator performance.

Engine oil is not included. Purchase oil separately, using the viscosity and capacity listed in your generator’s owner’s manual.

What’s in the Kit

• 1 UGP air filter — replaces Generac 0J8478S
• 1 genuine Generac 070185ES oil filter
• 2 Champion RC12YC spark plugs, or equivalent
• 1 foam pre-cleaner
• 1 oil funnel
• 1 service cloth
• 1 instruction sheet
• 1 maintenance reminder sticker

UGP Parts vs. Genuine Generac Parts

This is a mixed-component kit, so it’s worth being specific about what’s what:

• UGP replacement part: the air filter, engineered to fit in place of Generac part 0J8478S.
• Genuine Generac part: the 070185ES oil filter.
• Champion (or equivalent): the RC12YC spark plugs.

None of this affects fit or function — each component is selected to service the same maintenance points as the OEM kit — but if “genuine Generac” matters to your service records or warranty documentation, know that the air filter specifically is a UGP part, not a Generac-branded one.

Compatibility

Designed for select 16–26kW air-cooled Generac home standby generators. See the full compatibility list below and always verify your generator’s model and serial number before ordering — those numbers are printed on a data plate inside the generator’s enclosure, near the control panel.

Maintenance Guidance

Service intervals vary by model, run hours, and operating environment (dusty or high-use environments typically need more frequent service). Always follow the interval, oil specification, and installation steps listed in your generator’s owner’s manual — this kit provides the parts, not a substitute for manufacturer-specific instructions.

Before ordering, locate your generator’s model and serial number on the data plate inside the enclosure, near the control panel, and confirm it appears in the list below.
