Vehicle Compatibility Table

Function

Seals the contact surface between the spark plug and cylinder head to prevent combustion chamber leaks, oil/coolant seepage, and ensures stable engine compression.

Product Features

1. Precision Engineering

   • Exact OEM dimensions ensure perfect fitment in BMW cylinder heads

   • Maintains proper spark plug protrusion for optimal combustion

2. Advanced Material Technology

   • Multi-layer construction prevents blow-out under high boost pressure

   • Integrated metal ring prevents over-compression

3. Thermal Performance

   • Specialized rubber compound resists hardening from heat cycles

   • Maintains elasticity in extreme temperature fluctuations

4. Fluid Resistance

   • Impervious to engine oils, coolants and combustion byproducts

   • Prevents oil seepage into spark plug wells

5. Installation Advantages

   • Pre-lubricated for easier installation

   • Audible "click" when properly seated

   • No additional sealants required

6. Quality Assurance

   • Manufactured to BMW Group standards

   • 100% pressure tested before shipment

   • Meets ISO 9001 and IATF 16949 certifications

Technical Notes

• Critical Replacement Interval: Must be changed with every spark plug service (BMW recommends every 30,000-60,000 miles)

• Failure Symptoms: Oil in spark plug wells, misfire codes (P0300), reduced engine compression

• Storage Conditions: Store in original packaging at <30°C and <70% humidity

• Shelf Life: 5 years from manufacture date when stored properl

Replacement Guidelines

When to Replace:

• After spark plug removal (OEM gaskets are single-use; reusing may cause leaks).

• If engine shows oil leaks, low compression, or oil residue near spark plug wells.

Installation Steps:

• Remove ignition coil and old spark plug.
• Clean carbon/oil debris from the cylinder head’s spark plug hole.
• Install new gasket (often pre-attached to spark plug; press firmly into place).
• Torque spark plug to specification (avoid over-tightening to prevent deformation).
