ATV Spark Plugs, Plug Caps & Wires

ATV spark plugs are not glamorous. But they are essential components to your engine. A fouled or burned up plug will leave your wheeler running poorly or not at all. It’s always a good idea to have a couple spare plugs with you at all times. Of course, swapping spark plugs may get you home, but you still need to diagnose why the plugs are fouling. When you do swap spark plugs, you want to be sure you’re using a quality plug that is right for your wheeler. At Dennis Kirk you will find ATV spark plugs from top brands like NGK, Denso, and Autolite.

ATV spark plug wires and spark plug caps are also critical for performance. Plug caps are known to deteriorate and fail over time. You may notice bogging and lack of throttle response. This can be caused by worn plug caps. Most plug caps are easy to replace. Ensure the caps are tight and are secure on the plug. Broken or frayed spark plug wires can also be the culprit for a no spark or weak spark condition.
