Craftsman CMXGZAM250012 Current Walk 2 BPR6ES 751-10292 Spark Plug, Black

What It Is

The Craftsman CMXGZAM250012 is a replacement spark plug (cross-referenced as BPR6ES or 751-10292) designed for current-model Craftsman walk-behind lawn mowers. It ignites the air-fuel mixture in the engine cylinder, ensuring reliable starting and smooth operation.

Fitment & Compatibility

• Check your mower model number: This plug fits most Craftsman walk-behind mowers with Briggs & Stratton engines (e.g., 550e, 625e, 725e series) and some OHV models. Verify your mower’s model number on the deck or under the seat.
• Measure the gap: The factory gap is 0.030 inches (0.76 mm). Confirm this matches your engine spec—using a feeler gauge before installation is critical.
• Reach and thread size: It has a 14mm thread diameter and 19mm (3/4-inch) reach. Measure your old plug’s thread length to ensure it seats correctly.
• OEM vs aftermarket: This is a genuine Craftsman/OEM replacement, not a universal aftermarket plug. If you have a different brand (e.g., Husqvarna, Troy-Bilt), cross-reference the NGK BPR6ES or Champion equivalent.

Key Things to Know

• Installation difficulty: Easy—just a spark plug socket, ratchet, and gap tool needed. No special skills required.
• Common gotcha: Over-tightening can crack the insulator. Torque to 20-25 ft-lbs (hand-tight plus a quarter turn with a socket).
• Quality note: The platinum tip offers longer life than standard copper plugs—expect 100+ hours of use before replacement.
• Performance tip: Use a dielectric grease on the boot to prevent moisture and corrosion, especially in humid conditions.

Should You Buy It

Yes, if you own a Craftsman walk-behind mower with a Briggs & Stratton engine and need a reliable, OEM-spec plug. It’s priced fairly and has strong user feedback for easy starts and consistent firing. Skip it if you have a different brand or need a universal aftermarket plug—cross-referencing is safer.
