Detailed Description

The Denso Iridium Long Life 5087 spark plug is designed for vehicles that require a tapered-seat plug with the specified heat range, reach, and thread dimensions. Its iridium tip helps maintain consistent ignition characteristics over extended service intervals, while the platinum chip ground electrode supports wear resistance under repeated heat cycles.

This part cross-references DENSO Auto Parts ZT20EPR11 and Audi 101 000 052 AA for the same application.

Common Problems This Part Can Address

• Rough idle caused by worn spark plug electrodes
• Hard starting from weak or inconsistent spark output
• Misfire conditions related to plug wear or incorrect gap
• Reduced fuel economy from incomplete combustion
• Emissions issues tied to degraded ignition performance

Installation Notes and Tips

Verify the vehicle’s required thread diameter, reach, seat type, and heat range before installation. Confirm the listed fitment for your exact year, make, and model, since some applications note special requirements. Use the correct 16.0 mm spark plug socket and follow the manufacturer’s torque specification for the engine.
