Air Filter Spark Plug for 625e 675ex 725ex 625-675 Series TB110 TB130 TB210 TB230 Lawn Mower

What It Is

This is a bundled air filter and spark plug set designed for small engines in the 625e, 675ex, 725ex, 625-675 series models, plus TB110, TB130, TB210, and TB230 trimmers/blowers. It replaces both consumables in one purchase for routine maintenance.

Fitment & Compatibility

• Exact models: Fits Troy-Bilt, Craftsman, and Cub Cadet 625e, 675ex, 725ex, and all 625-675 series engines. Also covers TB110, TB130, TB210, TB230 trimmers/blowers.
• Check your engine: Look for a stamped model number on the engine shroud (e.g., 625e, 675ex). This set is not universal—verify your engine’s air filter and spark plug specs match.
• OEM vs aftermarket: This is an aftermarket part, not OEM. Expect slight cosmetic differences but functional compatibility if dimensions match.
• Measurements: The air filter is typically 1.75” x 1.5” x 1.0” (paper element). The spark plug is a standard 14mm thread, 3/4” reach, with a 13/16” hex. Confirm your plug gap (usually 0.030”) before installation.

Key Things to Know

• Quality: At $8.99, it’s a budget set. Some users report the filter feels less dense than OEM; the plug may have a shorter lifespan.
• Installation: Easy—remove old filter and plug, swap in new ones. No special tools needed beyond a spark plug socket.
• Gotcha: The spark plug may arrive with incorrect gap. Always check and adjust with a gap tool before installing.
• Not for all models: Double-check your engine series—this won’t fit larger 7000-series or older 600-series engines.

Should You Buy It

Good for a quick, low-cost replacement if you’re on a tight budget and need both parts at once. Skip it if you want OEM durability or if your engine requires a specific plug heat range or filter shape—buy separate, verified parts instead.
