HG Ignition coilpack, Mercedes M133 / M270/ M274 engines

High performance ignition coil upgrade for Mercedes-Benz M133, M270 and M274 engines

This HG Motorsport ignition coil is a performance-focused upgrade for Mercedes-Benz turbocharged M133, M270 and M274 engines. Compared to the factory ignition coil, it delivers a stronger and more stable spark, especially under high load and elevated temperatures.

It is an excellent replacement for worn OEM coil packs, while tuned and remapped engines benefit even more from the improved ignition stability. Depending on the setup, this can result in smoother combustion and potentially a small power gain.

Technical comparison: OEM vs HG Motorsport

In real-world use, this translates to improved ignition reliability, better heat resistance and consistent performance in conditions where OEM coils start to reach their limits.

• Stronger and more stable spark than OEM coil packs
• Ideal replacement for aging factory ignition coils
• Suitable for stock and tuned engines
• Improves ignition reliability under high boost
• Direct plug and play installation
