Set of 16 spark plugs MOPAR SP143877AB for CHRYSLER DODGE JEEP 5.7L HEMI

Set of 16 Spark Plugs MOPAR SP143877AB for CHRYSLER DODGE JEEP 5.7L HEMI

Original Quality for HEMI Engines

This set of original Mopar iridium spark plugs is specifically engineered for high-tech 5.7-liter HEMI series engines. Utilizing factory components ensures full compliance with the technical specifications of Chrysler, Dodge, and Jeep manufacturers, guaranteeing stable ignition system performance across all operating conditions. As shown in image 08_2.jpg, the spark plugs are supplied in individual packages collected into master boxes to protect the electrodes during transit.

Iridium Electrode Technology

The iridium-tipped center electrode offers exceptional wear resistance and a high melting point. This maintains a stable spark gap throughout the entire service interval, which is critical for engines with two spark plugs per cylinder, such as the 5.7L HEMI. The application of original Mopar technologies promotes more complete combustion of the fuel-air mixture, optimizing fuel consumption and ensuring reliable engine starts even in low temperatures.

Reliability and Durability of Components

The spark plug shell is constructed from a high-quality metal alloy with a corrosion-resistant coating, while the insulator is made of dense ceramic resistant to voltage leaks and sudden temperature changes. The design of the SP143877AB spark plugs (previously known under part number SPLZFR5C11) focuses on maximizing radio frequency interference (RFI) reduction and ensuring the seal of the combustion chamber.

Detailed Compatibility Table

This set is intended for Stellantis (formerly FCA) vehicles equipped with 5.7L V8 HEMI engines from 2011 and later.
