BlueStars Tune-Up Kit for John Deere & Kohler Engines - GY20661 with Air, Oil, Fuel Filters and Spark Plug

BlueStars GY20661 is a complete tune-up kit containing a pleated air filter with foam pre-cleaner, oil filter, fuel filter, and spark plug designed to fit Kohler engines used on many John Deere and Toro mowers.

This kit gathers the four most commonly replaced maintenance parts into one package so you can perform a routine service quickly and with confidence. Each component is matched to the listed replacement numbers and compatible models, and the kit includes a reinforced air filter seal and a corrosion-resistant oil filter housing to help protect your engine from dirt, debris, and contaminants that reduce performance.

Will these parts fit my John Deere or Kohler engine?

Compatibility covers a wide range of Kohler CV engines and many John Deere models that use Kohler powerplants. Check your engine model and part numbers against the replacements listed to be certain.

• Fits Kohler CV11–CV16 large-capacity engines and CV460–CV490 ranges.
• Matches John Deere part references GY20661, M131303, M145944 and common mower models like LT160, LX266, L110.
• Cross-references include Kohler numbers 12 083 10, 12 083 16 and oil filter codes such as 25 050 27.

How does the air filter and pre-cleaner protect my engine?

The pleated paper air element traps fine particles while the foam pre-cleaner captures larger debris before it reaches the main media. This staged filtration reduces dust ingestion and helps preserve airflow for steady combustion.

• Pleated paper media for high dirt-holding capacity without restricting air.
• Foam pre-cleaner improves large-particle capture and extends filter life.
• Polyurethane seal holds shape to maintain a tight, contaminant-blocking fit.

What benefits does the oil and fuel filter provide during tune-up?

The included oil filter uses synthetic fiber media and a rust-resistant metal housing to remove suspended contaminants from oil and maintain consistent flow. The fuel filter screens out particulates and helps keep fuel delivery components clean for reliable starting and steady throttle response.

• Synthetic filtration media in the oil filter for efficient contaminant removal.
• Corrosion-resistant oil filter housing for longer service life.
• Fuel filter protects carburetors and injectors from debris and varnish.

How easy is it to install these items during routine maintenance?

These replacement parts are designed to be direct-fit for the referenced engine and mower models, simplifying installation for DIYers and mechanics. Basic hand tools and a clean workspace are typically all that’s needed to swap the filters and spark plug during a standard tune-up.

• Direct-replacement dimensions and seals that align with factory housings.
• Includes the four parts usually replaced together—air, oil, fuel, spark plug.
• No modifications required for compatible Kohler and John Deere models listed.

Who is this for: This BlueStars GY20661 tune-up kit is aimed at lawn care professionals, landscapers, and homeowners who maintain John Deere, Toro, or other mowers powered by Kohler CV-series engines. It’s useful for anyone wanting a complete, matched set of consumables for routine seasonal maintenance, reducing shopping time and ensuring correct replacement parts when servicing 11–16 HP engines.
