2Pack L7T Spark Plug for NGK BPMR7A & Champion CJ8, RCJ6Y, RCJ7Y - Universal Replacement for Stihl, Husqvarna 2-Stroke Chainsaws, Lawnmower Brushcutter Strimmer Engine

What It Is

This is a 2-pack of L7T spark plugs designed as a universal replacement for NGK BPMR7A, Champion CJ8, RCJ6Y, and RCJ7Y plugs. It fits 2-stroke engines in Stihl and Husqvarna chainsaws, lawnmowers, brushcutters, and strimmers.

Fitment & Compatibility

Before buying, check your engine’s spark plug gap (typically 0.024–0.028 inches for these models) and thread size (14mm x 19mm reach). This plug is a direct replacement for OEM part numbers: NGK BPMR7A, Champion CJ8, RCJ6Y, RCJ7Y. It fits most Stihl and Husqvarna 2-stroke equipment, but also works in many Echo, Ryobi, and Craftsman trimmers/mowers. Measure your old plug’s thread length and gap to confirm. Not for 4-stroke engines or larger displacement machines (over 60cc).

Key Things to Know

• Quality: Budget-friendly aftermarket plug; fine for routine use, but may not last as long as OEM NGK or Champion plugs in heavy-duty or frequent-use applications.
• Installation: Easy—remove old plug, gap the new one to spec (use a feeler gauge), hand-tighten, then snug with a socket. Over-tightening can strip threads.
• Gotcha: The L7T is a non-resistor plug. If your engine requires a resistor plug (e.g., for radio interference suppression), check your manual—using this could cause ignition noise.
• 2-pack value: Great for keeping a spare on hand, especially if you have multiple 2-stroke tools.

Should You Buy It

Buy this if you need a cheap, functional replacement for common 2-stroke small engines and don’t mind slightly shorter lifespan than premium brands. It’s ideal for occasional users or as a backup set. Skip it if you run equipment daily or need exact OEM specs for warranty or performance.
