Champion 3470 Spark Plug

Champion Platinum Power Spark Plug 3470

Champion Platinum Power spark plug 3470 is built for steady ignition performance in secondary ignition systems. It uses a platinum center electrode, a nickel ground electrode core, and a tapered seat design to support sharp spark focus and consistent combustion. This plug is a direct-fit option for select Chrysler, Dodge, and Saturn applications, including PT Cruiser, 300, Sebring, Charger, Magnum, Stratus, and LW1 models.

Platinum Power Design

The Platinum Power line focuses on durable ignition performance with a fine-wire center electrode and a V-trimmed ground electrode profile. Champion’s Heat-Active alloy construction is used to manage heat transfer, while the resistor design supports stable operation in modern ignition systems. Part number 3470 is also identified as plug type RE14PMC5.
