Set of 16 spark plugs Mopar SP149212AC Dodge Charger Jeep Chrysler V8

Set of 16 Mopar SP149212AC Spark Plugs for Dodge Charger Jeep Chrysler V8

Original Quality for HEMI V8 Engines

This set of 16 spark plugs is a Genuine OEM replacement part manufactured by Mopar, specifically engineered for modern high-performance eight-cylinder engines from the Stellantis group (Chrysler, Dodge, Jeep, RAM). Using original spark plugs guarantees full compliance with factory tolerances for heat range and spark gap. This is critically important for the correct operation of ignition systems in 5.7L and 6.4L HEMI engines, where there are two spark plugs per cylinder. The original equipment design ensures stable engine starting in all temperature conditions and preserves factory power ratings.

Platinum Coating Technology and Durability

The Platinum series spark plugs feature a center electrode with precious metal plating, which significantly increases their resistance to electrical erosion and the effects of high temperatures within the combustion chamber. Platinum allows for a smaller electrode diameter, which concentrates the spark charge and facilitates the ignition of the air-fuel mixture. This directly impacts fuel economy and the reduction of exhaust emissions. Due to the high wear resistance of the material, the replacement interval for these plugs is significantly higher than that of standard nickel counterparts, reducing overall vehicle maintenance costs.

Operational Stability and Electronics Protection

The body of the Mopar SP149212AC spark plugs is treated with an anti-corrosive galvanic coating that prevents the threads from seizing to the cylinder head. An internal resistor effectively suppresses radio frequency interference generated during spark formation, protecting the vehicle's onboard electronics, sensors, and multimedia systems from interference. The ceramic insulator with high dielectric strength eliminates spark flashover past the electrodes, ensuring stable engine performance at idle and under peak loads at high speeds.
