PartSelect Number PS9263506
Manufacturer Part Number 15901019830
This Spark Plug Bpm-8y is a silver and white OEM part. Made of steel and ceramic it is individually sold, and is an electrical part. It is installed with a spark plug socket and is rated as Easy to install. It is attached inside of the cylinder head, and is used to ignite the air fuel mixture inside the combustion chamber.
You can clean the spark plug with a fine sandpaper of 180 or more, then spray it with carburator cleaner and wipe dry. However, even after regular maintenance, spark plugs need to be changed as part of good engine fine-tuning. Regap to manufacturer specifications. Refer to your owners manual or model number to ensure you are choosing the correct product.
Note: If your engine has more than one cylinder and sounds like it has a miss, you can remove each spark plug wire one at a time to find the miss. If the engine drops in rpm when you remove the wire, then that cylinder is fine, if it does not drop then you have found your miss!

Engine Spark Plug
PartSelect Number PS10036953
Manufacturer Part Number 98079-56846
This is an OEM spark plug designed for engines to ignite the air-fuel mix inside the combustion chamber. This plug is white and silver, and made of metal and ceramic materials. Over time, the spark plug can become fouled due to a range of reasons, including a poor air-to-fuel ratio, worn piston rings, carbon-build-up, and general wear and tear.
You can clean a lightly worn spark plug with fine sandpaper and carb cleaner and re-install, but generally you are going to have to replace this part often, and it is better to replace a fouled plug than try to clean it. If your spark plug is in bad condition you may experience a missed start, or a no-start situation. If the engine has 2 or more cylinders you can pull the spark plug wire off to see if the RPMs are dropping due to a miss.
On a single cylinder, a malfunctioning spark plug is more likely to cause a no-start issue. When replacing the spark plug, be sure you torque to the manufacturer specs.
Most customers found this repair easy, you will just need a spark plug socket.

This part is the replacement spark plug for your engine. It measures approximately 2.5 inches by 1 inch. The spark plug creates the spark that ignites fuel in your engine during the combustion process. Over time, spark plugs can become worn and can go bad, which will prevent the engine from firing. You can test your spark plug for continuity with a multimeter, and inspect it for corrosion if you suspect the spark plug has gone bad. This is an OEM part sourced directly from the manufacturer and it is sold individually.

Engine Lawn Mower Spark Plug
PartSelect Number PS9314547
Manufacturer Part Number BPR4ES
This NGK BPR4ES spark plug is sourced from the original manufacturer for use in a variety of small engines. It is responsible for igniting the fuel-air mixture in the engine cylinder, needed for the engine to operate. The spark plug is a small, cylindrical part consisting of a metal body, a ceramic/porcelain insulator, one center electrode, and one ground electrode. The spark plug can fail if the insulator breaks, the electrodes wear down, or if it becomes fouled. If the spark plug has failed, you will experience difficulties starting your equipment, decreased power output, and engine misfiring. To check if the spark plug is faulty, you can use a spark tester or a multimeter set to continuity. To replace the spark plug, first disconnect the spark plug wire, and then use a spark plug socket wrench to loosen and remove the old spark plug. Take the new spark plug and set the gap to the correct size. Thread it into the cylinder head using your hands to avoid cross-threading. Once it is in place you can finish tightening it with the spark plug socket wrench. Reconnect the wire, and the equipment should be ready to run smoothly again.
