• Fast Heating Time: Reaches operating temperature within seconds, reducing idle time and improving fuel efficiency.
• Long Service Life: Designed to withstand thousands of engine cycles without degradation.

Applications

The Metzger H1 087 is engineered for use in a variety of Mercedes-Benz models, including:

• C‑Class (Berline and Break variants)
• E‑Class (Berline and Break variants)
• G‑Class
• S‑Class

Its universal design allows it to be installed in any engine that requires a glow plug of the M12×1.25 specification, making it suitable for both new builds and aftermarket replacements.

Installation Guidelines

1. Preparation: Disconnect the vehicle’s battery to prevent accidental electrical discharge.
2. Removal of Old Plug: Use a socket wrench with an extension bar to unscrew the existing glow plug. Keep track of any retaining clips or seals.
3. Cleaning: Clean the cylinder head threads with compressed air and a thread‑cleaning brush to remove debris.
4. Installation: Align the new Metzger H1 087, hand‑tighten until snug, then torque to the manufacturer’s specification (typically 30–35 Nm).
5. Reassembly: Replace any seals or clips removed during removal. Reconnect the battery.
