6PCS Iridium Spark Plugs SP149125AE | Compatible with 2011-2021 Dodge Jeep 3.6L Engines

This set of 6 iridium spark plugs is designed to fit a wide range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 3.6L engine. With the OEM part number SP149125AE, this direct replacement helps restore engine performance, fuel economy, and smooth idling. Each plug features a fine-wire iridium electrode for long service life and consistent ignition.

Iridium spark plugs provide a hotter, more reliable spark than standard copper plugs. This leads to better throttle response and reduced misfires.

Whether you are doing a routine tune-up or replacing worn-out plugs, this set gives you six plugs to replace all cylinders at once. Using matching plugs ensures balanced combustion and helps maintain engine health over time.
