Spark Plugs 101

ATV Spark Plugs From Rocky Mountain ATV/MC

Need a new spark plug for your ATV? It may be small and unimpressive, but it performs a role that is absolutely vital. Without it, the internal combustion engine can’t combust – which is bad if you actually want to go anywhere. However, unlike most problems that prevent the motor from running, a bad spark plug is easily replaceable. Anyone can do it. That’s why a lot of riders carry along a spare (or two) on their quad. That way, if it goes out, it doesn’t ruin a day on the trail. We carry pack-a-plug containers and spark plug wrenches for this very reason.

Regardless of what you’re looking for in a spark plug, you’ll find it here at Rocky Mountain ATV/MC. We have standard replacement spark plugs, perfect for most needs and easy on the wallet. However, we also carry a variety of enhanced spark plugs which offer greater reliability and longevity and are ideal for ATV racers or those riders who practically live on the trail. These spark plugs have variances in shape, design or construction material.

If it’s time to get a new spark plug for your quad, you’re in the right place. Browse our impressive selection and pick one up today.

    Simple item, nice finish, works well, great price!

    Item works excellent. It has very thin sidewalls allowing it to gain access to tight areas on modern engines. Invaluable to have in your toolbox. Finish is nice and the price is outstanding!

    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.
