Description
Overview:
This Spark Plug Cap Spring is a genuine Stihl component designed to maintain a firm electrical contact between the spark plug terminal and the ignition cap. Manufactured from durable spring steel, it keeps consistent pressure on the contact point for a reliable spark. It is engineered for Stihl two-stroke machines across chainsaws, cut-off saws, brushcutters, blowers, mistblowers and more, including the TS350 and TS360. Replacing a tired, bent or lost spring helps prevent misfires, hard starting and intermittent running. Identified by MPN 0000 998 0603, it is a direct-fit replacement that supports dependable ignition performance under vibration and heat. It's a small, low-cost part that makes a big difference to engine starting and running quality.
