A common issue with high performance four stroke motorcycles and ATV’s is heat build up during extreme conditions.  Added heat to an engine during this time can create an opportunity for the spark plug cap to loosen or “pop off” creating less than optimal performance. At Tw1sted Development Racing we came up with a solution to mitigate this potential risk.   We have developed a device that will keep constant pressure on the spark plug cap preventing it from raising and/or popping off during long motos and heat cycles, maintaining a constant contact between the spark plug and spark plug cap. A simple to install product that meets the demands of the racer.  Installation is easy with the replacement of a single bolt and placing the device over the spark plug cap.
