LTX 1045 Air Filter Tune up Maintenance Kit for Cub Cadet LT1042 LT1045 LTX1040 LTX1042 LTX1045 RZT42 Toro 98018 LX420 LX460 Lawn Mower

What It Is

This is a complete tune-up kit for select Cub Cadet and Toro lawn tractors, containing an air filter, fuel filter, spark plug, and oil filter. It’s designed for regular maintenance to keep your engine running clean and efficient.

Fitment & Compatibility

Before buying, verify your mower’s model number (e.g., LTX 1045, LT1042, RZT42) and engine type—this kit fits Kohler Courage or Command engines (common on these models). Check the spark plug gap (usually 0.030″ for these engines) and confirm the oil filter thread size (3/4”-16 is standard). The air filter is a rectangular foam element; measure your existing filter to ensure it matches (roughly 6″ x 4″ x 1.5″). This is an aftermarket kit, not OEM Cub Cadet, but it meets OEM specs for the listed models. Avoid using on newer Cub Cadet models with different engine families (e.g., 7000 series).

Key Things to Know

• Quality: Filters and plug are well-made; oil filter has a steel case and anti-drainback valve, matching OEM performance.
• Installation: Easy—no special tools beyond a socket wrench for the spark plug (5/8″) and oil filter wrench. Takes 15-20 minutes.
• Gotcha: The spark plug may arrive pre-gapped; always double-check with a feeler gauge before installing. The fuel filter is a universal inline type; you may need to cut your fuel line to fit.
• Common issue: The air filter foam can be slightly thicker than OEM; it may need gentle compression to seat properly in the housing.

Should You Buy It

If you own a compatible Cub Cadet or Toro tractor and want a budget-friendly, complete maintenance kit that covers all four filters/plugs in one purchase, this is a solid choice. It’s ideal for DIY owners who do their own seasonal tune-ups and don’t need OEM branding. Skip it if you prefer genuine Cub Cadet parts or have a different engine family.
