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!

    NGK Iridium plug 2010 KTM 450XCW Fantastic reliabil...

    I replaced my plug on a 2010 KTM 450XCW jus this year. The bike has always started well, LI-Fe battery since 2016. However, I noticed it started to take more pushes of the button or more than one kick. I changed the plug, upgraded to NGK iridium series and HOLY WOW! One push starts and simple kicks. My old plug looked good too. Chocolate milk brown. I've got a 2006 RMZ450 and I have a new NGK iridium for that bike next! Great plug. Great starts. Better than stock always.

    Spark Plug Carrier/Protector

    Spark plugs were extremely difficult to insert and remove in the carrier/protector. Had it been easier to use I would have given a 5 star rating.
