Generac 0G5894 Air Filter & 070185ES Oil Filter Kit for 20kW 999cc Generators

Description

Keep your standby generator running on clean air and clean oil with this genuine Generac air and oil filter kit. It pairs the Generac 0G5894 air filter with the 070185ES extended-capacity oil filter for routine servicing of select pre-2013, 20kW air-cooled generators equipped with 999cc V-twin engines.

The air filter helps prevent dirt and airborne debris from entering the engine. The oil filter captures contaminants circulating through the lubrication system. Replacing both filters according to the generator’s maintenance schedule can help support reliable operation and longer engine life.

What’s Included in the Generac Air and Oil Filter Kit

• 1 genuine Generac 0G5894 air filter
• 1 genuine Generac 070185ES oil filter

This 20kW generator filter kit covers the two filters needed for routine standby generator maintenance in one purchase. Engine oil and spark plugs are not included.

Why Replace the Air and Oil Filters Together?

Air and oil filters protect different parts of the engine. The Generac 0G5894 air filter keeps debris out of the intake, while the 070185ES oil filter works inside the lubrication system. Servicing both at the same interval keeps your maintenance routine simple. Always follow the maintenance schedule in your generator’s owner’s manual.
