Installation Notes and Tips

Verify the exact engine and cylinder application before ordering, especially on Mercedes-Benz models with cylinder-specific notes such as GLE63 AMG, GLS550, GL550, and ML550. Some fitments list cylinders 1, 5 or 2, 3, 4, 6, 7, 8 and note use without a protective sleeve, so match the vehicle configuration carefully. Inspect the spark plug, connector, and surrounding ignition components during installation to help confirm the root cause of the fault.

Quality Assurance
