BMW Motorcycle Spark Plugs
Motorcycle Spark Plugs Buying Guide
What They Do
Ignite the mixture of oxygen and fuel in your bike's engine. This is how the combustion process starts, and how the engine produces the power it runs on.
How They Work
The process, called spark ignition, involves an ignition switch, the motorcycle's battery, and a few other ignition parts. Together, they generate electricity, a charge that the plugs' leads pick up. Combustion happens, and your engine pistons, the crankshaft, the alternator, and more start running.
The Symptoms of a Bad One
Besides corrosion, physical deterioration, overly wide leads, conductivity problems, and outright breakage:
- Hard starts
- Worsening fuel economy
- Engine misfiring and backfiring
- A flooded engine
- Smelling gas at startup
- Gas spraying out of your exhaust pipe
- Idling roughly
- Having problems accelerating
When They Should be Changed
If you see said signs, or if you inspect your motorcycle's engine and the results recommend replacing them. Otherwise, check them every 4,000 to 5,000 miles and take care of the job before they exceed their suggested mileage limits -- around 8,000 to 10,000 miles. Most importantly, if you're looking to order new ones, be sure you get the genuine article.
Why Buy Genuine OEM Spark Plugs
BMW Motorrad builds them to fit your bike model specifically. That's a guarantee that the aftermarket may not always make.
