• Low Electrical Resistance: Minimizes power draw from the vehicle’s electrical system, preserving battery life.
• Compact Size: Fits standard engine bays without requiring modifications.

Compatibility Overview

The GN928 is engineered to fit a wide range of popular gasoline engines. Its standardized dimensions and threading allow seamless integration with many OEM models, including but not limited to:

• Audi: A4, A6, Q5, and other recent models.
• Ford: Focus, Fiesta, Mondeo, and various diesel‑gas hybrids.
• Seat: Ibiza, Leon, Toledo, and all current lineup.
• Skoda: Octavia, Superb, Kodiaq, and other mainstream vehicles.
• Volvo: S60, V60, XC90, and related models.
• Volkswagen: Golf, Passat, Polo, Tiguan, and many others.

Engineers have verified that the GN928’s M12 × 1.25 thread and 63 mm tapered length match the specifications of these brands’ cylinder heads, ensuring a secure fit without aftermarket adapters in most cases.

Installation Guidance

1. Remove the existing glow plug or spark plug with a 12 mm socket.
2. Clean the threaded area to eliminate debris and corrosion.
3. Insert the GN928, aligning the 4 mm PIN connection for proper seating.
4. Tighten to manufacturer’s torque specification (typically 30–35 Nm).
5. Reconnect the electrical harness, ensuring a firm contact.

For vehicles with unique engine configurations, consult the service manual or a qualified technician before installation.

Benefits for Vehicle Owners
