Spark Plugs 101

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!

  • Tusk Spark Plug Socket

    Tusk Spark Plug Socket

    A in NM

    Very nice. Convenient.

    This plug socket is nice, but many bikes still have to combat the issue of the coil being under the frame of the bike. Like mine. It helped a little at first, but when i got ready to pull the plug from the hole, I couldn't tilt the swivel enough without the socket and spark plug falling off of the swivel extension. Regardless, as I rarely ever had pull my down plugs, I'm not too concerned. Good, stout socket and swivel. Certainly recommend for the price!
