XT675 Carburetor Air Filter Tune Up Kit for Toro 22 Recycler Compatible for Lawn Mower with Kohler XT650 XT6.5 XT6.75 6.5hp 6.75hp 149cc Engine

What It Is

This is a complete tune-up kit for Toro 22-inch Recycler mowers powered by Kohler XT-series engines (XT650, XT6.5, XT6.75, 149cc). It includes a pre-oiled foam air filter, a paper air filter, a spark plug, and a fuel stabilizer—everything needed for a single-season service.

Fitment & Compatibility

Check your engine model: Only fits Kohler XT650, XT6.5, XT6.75, or 149cc engines. Do not buy for Briggs & Stratton or Honda engines.
Check your Toro model: Made for Toro 22-inch Recycler (e.g., 20333, 20334, 20339). Verify your mower’s model number under the seat or on the deck.
OEM cross-reference: Replaces Toro 108-594-01 air filter and Champion RC12YC or equivalent spark plug.
Physical check: The foam filter measures roughly 5" x 3" x 1"—measure your old filter to confirm.

Key Things to Know

• Quality is good for the price: Pre-oiled foam filter works well, but the paper filter is thinner than OEM. Expect to replace the paper filter mid-season if you mow dusty grass.
• Installation is easy: No tools needed for the filters—just remove the old ones and snap in the new. Spark plug requires a 5/8” socket.
• Common gotcha: The included spark plug may be gapped too wide out of the box (spec is 0.030”). Check and adjust gap before installing.
• Fuel stabilizer is a bonus: The included small bottle is enough for one tank—use it if you store the mower for winter.

Should You Buy It

Buy this kit if you own a Toro 22-inch Recycler with a Kohler XT-series engine and want a convenient, low-cost tune-up for one season. It’s a solid value for the price, but if you need longer filter life or premium components, stick to OEM parts.
