(Pack of 2) Champion Spark Plugs for Cub Cadet, MTD 759-3336, 7593336, 759336

What It Is

This is a pack of two Champion spark plugs designed for Cub Cadet and MTD lawn tractors, zero-turn mowers, and other small engines. It’s a direct replacement for OEM part numbers 759-3336, 7593336, and 759336, used to ignite the fuel-air mixture in the cylinder for reliable starting and smooth operation.

Fitment & Compatibility

Before buying, verify your engine’s make and model—these plugs fit many Briggs & Stratton, Kohler, and Kawasaki engines commonly used on Cub Cadet and MTD equipment. Check your current plug’s gap (typically 0.030” or 0.040”) and adjust if needed; the plug comes pre-gapped but may require fine-tuning. Also confirm the thread size (14mm) and reach (about 0.750”). Not compatible with older 2-stroke engines or models using resistor plugs with different heat ranges.

Key Things to Know

• Quality: Champion is a reputable brand; these are copper-core plugs with decent lifespan (roughly 100 hours or one season). Not as long-lasting as iridium but fine for standard use.
• Installation: Easy DIY job—remove the spark plug wire, unscrew the old plug with a socket wrench, and install the new one. Don’t overtighten; hand-tighten then a quarter-turn more.
• Common Gotchas: The plug may arrive with a loose gap—always check and adjust before installing. Also, if your engine uses a different heat range (e.g., for high-performance or high-deck mowers), these may foul or overheat.
• Pack of Two: Good for twin-cylinder engines or as a spare. If your mower has a single cylinder, you’ll have one for later.

Should You Buy It

Buy this if you need a budget-friendly, reliable replacement for a Cub Cadet or MTD mower with a compatible small engine, and you’re comfortable with a simple DIY swap. It’s a solid value for standard residential use, but skip it if you require premium iridium plugs for extreme conditions or a different heat range.
