You should always check your owner's manual for the exact specifications recommended by Dodge for your specific engine. The manual will list the correct plug type, heat range, and gap. Using the wrong plugs can damage your engine.
Commonly recommended plug types (but always verify with your owner's manual):
* Champion RC12YC4: A popular choice for 5.7L Hemi engines. Often chosen for a good balance of performance and lifespan.
* NGK Iridium IX (specific part number will vary depending on engine): Iridium plugs generally offer longer life and better performance than standard platinum plugs. They are more expensive upfront, but the longer lifespan can offset the cost.
* Autolite XP Iridium (specific part number will vary depending on engine): Another good option in the iridium category.
Don't just rely on brand names alone. The specific part number listed in your owner's manual or a reputable parts store's online catalog (cross-referencing your VIN) is crucial for ensuring you get the correct heat range and other specifications. Getting the wrong heat range can lead to overheating or fouling of the plugs.
In short: Consult your owner's manual for the exact recommended spark plugs. Then use a reputable parts store's online catalog or a parts professional to confirm the right part number for your vehicle. Don't guess!
