Important Notes

• Verify compatibility with your specific Husqvarna equipment model, product number, serial number, engine configuration, and production revision before ordering.
• Husqvarna identifies 503235111 as an NGK BPMR7A M14 x 1.25 spark plug.
• Match part number 503235111 with your equipment's illustrated parts diagram, owner's manual, or OEM service documentation before ordering.
• BPMR7A is the NGK spark plug designation; do not substitute a similar-looking plug without verifying its thread size, reach, heat range, resistor configuration, and electrode specifications.
• The “R” in BPMR7A identifies the plug as a resistor-type spark plug.
• Spark plug condition can directly affect engine starting, idle quality, acceleration, combustion, and overall engine performance.
• A fouled plug may result from an overly rich fuel mixture, excessive oil, repeated short-duration operation, carburetor problems, or other engine conditions.
• A damaged or abnormally colored spark plug can sometimes indicate an underlying engine, carburetion, ignition, or fuel-mixture issue.
• Inspect the spark plug boot, ignition lead, ignition module, cylinder threads, and surrounding components during replacement.
• Clean dirt and debris from around the spark plug before removal to help prevent contaminants from entering the cylinder.
• Allow the engine to cool before removing or installing the spark plug.
• Start the replacement spark plug by hand whenever possible to reduce the risk of cross-threading the cylinder head.
• Do not overtighten the spark plug. Follow the torque specification provided for your specific Husqvarna equipment.
• Verify and adjust the spark plug electrode gap according to the specification for your exact equipment model rather than assuming one universal gap for every application using BPMR7A.
• Replace a spark plug with cracked porcelain, damaged threads, excessive electrode wear, severe carbon buildup, or other physical damage.
• This listing is for one Husqvarna 503235111 NGK BPMR7A M14 x 1.25 Spark Plug only unless otherwise specified. Spark plug boots, ignition modules, ignition leads, carburetor components, and other tune-up parts are sold separately.
