When it comes to dirt bikes, the little things make a big difference. You can spend all the money you want on fancy intakes, headers and exhausts – but if your spark plug isn’t sparking, or your solenoid switch wire is frayed, then none of that will matter. Make sure you always get to the start and finish lines by using quality dirt bike spark plugs, wires and switches from Dennis Kirk. We carry OEM replacement and performance parts so you never have to worry about the little things when you’re riding.

Each spark plug we sell is designed to outperform its OEM counterpart. Whether you choose the superior heat dissipation of an NGK spark plug, the quick ignition of a PowerMadd spark plug, or another of your favorite brands, you’ll get premium long-lasting performance. Spark plugs are one of the most inexpensive parts on a dirt bike, so pick up a second plug while you’re here, and even a spark plug carrier so you’ll always have a spare with you at the track or on the trail. With our fitment guide, you can easily find which spark plugs will match your bike.

Our wires and switches will also help you get fired up and keep you under control. We offer dirt bike spark plug wires, starter switches, ignition switches and other parts to keep your entire starting system in top shape. Our replacement handlebar control switches allow you operate your turn signals, headlights, parking lights, horn and more from a single control box. We also have individual brake light switches, kill switches and even secure USB charging systems for your mobile electronics.

We carry dirt bike parts from Motion Pro, Moose, K & S and other leading brands so you know you’re always getting a quality product. Dennis Kirk has been a leader in the powersports industry for nearly half a century, and with our selection of spark plugs, wires and switches, we have every inch of your bike covered. Enjoy free shipping if your order exceeds $89, and we also offer no-hassle returns and exchanges.
