Dirt Bike Spark Plugs

Spark plugs are an essential part of every dirt bike engine. When the spark plug stops sparking, the engine is completely inoperable. That’s when it’s time to turn to Rocky Mountain ATV/MC. We carry many dirt bike spark plugs to ensure that you’re always on the go. And with such great prices, why not pick up a spare? That way, you’ll always be prepared for the worst, and you won’t have to worry about a simple spark plug placing a dreaded DNF on your race results. We’ve even got spark plug holders for your spares!

We’re proud to carry one of the leading manufacturers of dirt bike spark plugs: NGK. Each plug is specially designed for each bike and replaces the stock part. (If you’d prefer an OEM spark plug, we’ve got those too – just click the OEM button at the top of the page.) Our proprietary Parts Finder makes it easy to determine exactly what fits your bike. We carry several types of spark plugs, including high performance spark plugs. Iridium spark plugs are among the most popular available due to their long lifetime. If you’re part of the motocross scene, don’t pass up on a racing spark plug! When you need a new spark plug for your dirt bike, Rocky Mountain ATV/MC is your solution!

  • Motion Pro Spark Plug Socket

    Motion Pro Spark Plug Socket

    Tibbits in UT

    Well built but...

    It's a well built 18mm socket with several different ways of turning: wrench, socket, even has a hole if you need to break it loose with a screwdriver, (on tight applications where sockets won't fit.) But it does not fit into the small area on the XR400s, better to go with the Honda OEM thin walled socket.
