32 883 09-S1 KT730 Air Filter Tune Up Kit for Kohler 7000 Series KT715 KT725 KT735 KT740 KT745 KT610 KT620 Engine, Compatible with Cub Cadet XT1 LT46 LT50 XT2 LX42 LX46 Lawn Tractors

What It Is

This is a complete air filter and spark plug tune-up kit for Kohler 7000 Series KT engines (models KT610 through KT745). It’s designed for routine maintenance on Cub Cadet XT1, XT2, and LX series lawn tractors, typically during spring or after 100 hours of use.

Fitment & Compatibility

Engine check first: This kit fits Kohler KT610, KT620, KT715, KT725, KT735, KT740, and KT745 engines. Look for the engine model number printed on the valve cover or near the air filter housing—don’t rely on the tractor model alone.

Tractor compatibility: Works with Cub Cadet XT1 LT46, LT50, XT2 LX42, LX46, and similar models using those Kohler engines. Other brands (e.g., John Deere, Husqvarna) with the same engine will also fit, but verify the air filter housing shape.

Measurements: The air filter is approximately 6.5” x 4.5” x 2” (pre-cleaner is separate). Spark plug is a standard 14mm thread, 3/4” reach—measure your old plug gap before installing (0.030” typical).

OEM vs aftermarket: This is an aftermarket kit, not genuine Kohler. It matches OEM part numbers 32-883-09-S1 (air filter) and 25-132-03-S (spark plug). Cross-check your engine’s air filter part number on the Kohler site.

Key Things to Know

• Installation difficulty: Easy—20 minutes with basic tools. Remove the air filter cover, swap the filter and pre-cleaner, then replace the spark plug with a socket wrench.
• Quality: One review (5.0 stars) suggests it’s reliable, but aftermarket filters may have slightly less filtration media than OEM. For heavy dust or frequent mowing, consider genuine Kohler.
• Common gotcha: The pre-cleaner foam may be too tight or too loose on some housings—test fit before reassembling. Also, the spark plug may come pre-gapped; always double-check with a feeler gauge.
• Not included: Oil filter, fuel filter, or air filter cover gasket—sold separately.

Should You Buy It

At $8.99, this kit is a solid budget option for a quick tune-up on a Kohler 7000 Series engine in a Cub Cadet tractor. It’s right for DIY homeowners who want to replace both the air filter and spark plug at once without hunting for separate parts. If you need OEM-grade durability for commercial use or heavy dust conditions, spend more on genuine Kohler parts.
