Description
Overview:
This Spark Plug Boot is a Genuine Stihl part (OEM 4180 405 1000) designed to restore and protect the ignition connection on small petrol engines. It fits directly onto the spark plug terminal and the high-tension (HT) lead to deliver a consistent spark while insulating the connection against heat, vibration, and moisture. Built with durable, heat-resistant rubber and a secure internal connector, it maintains a firm grip on the plug to help prevent misfires and arcing. Ideal for routine servicing or replacing a cracked or perished cap, it suits a wide range of Stihl machines used for landscaping and grounds maintenance, including the KM90 and KM90R multi-tools.
Key Features:
- Genuine Stihl component for assured fit and performance (OEM 4180 405 1000)
- Durable, heat- and vibration-resistant rubber insulation for long service life
- Right‐angle boot for neat HT lead routing and reduced strain at the plug
- Firm internal connector for a secure, consistent spark plug connection
- Helps prevent arcing, tracking, and moisture ingress at the plug top
- Supports reliable starting and stable running under load
- Direct replacement for worn or damaged boots; quick to fit with basic tools
- Suitable across brushcutters, Kombi engines, hedge trimmers, blowers, and augers
Typical Applications:
Used during ignition system maintenance or repair when engines are hard to start, misfiring, or when the existing boot is cracked, loose, or heat‐damaged. Common in regular servicing of professional and domestic machines to maintain safe insulation around the spark plug. Favoured by landscapers, contractors, councils, and homeowners for dependable running in daily trimming, cutting, blowing, and drilling tasks.
Also known as:
Often referred to as a spark plug cap, ignition cap, HT cap, coil lead cap, plug cover, suppressor cap, or spark plug connector. It finishes the HT lead and clips to the plug terminal to carry high voltage while insulating the connection from the engine.
