Installed as a full 16-plug kit, they arrive pre-gapped to 0.044' and match the Dual Plug fitment required by the 2011-2021 Ram 1500 HEMI engines, which makes them a convenient one-stop service part for a tune-up. The most compelling reason to buy is the increased spark efficiency that translates to smoother idle and better throttle response without complicated installation steps.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine NGK Parts:\u003c\/strong\u003e Built to the specifications of a leading spark plug maker so fitment and reliability align with original equipment expectations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduce Emissions and Misfires:\u003c\/strong\u003e The Iridium IX design promotes complete combustion, which helps lower exhaust emissions and reduce the chance of misfires during operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Shell:\u003c\/strong\u003e A robust shell protects the plug body from damage and corrosion, helping the plugs maintain performance over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproved Ignition Efficiency:\u003c\/strong\u003e Advanced center and ground electrodes focus the spark for stronger combustion that supports smoother idle and crisper throttle response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamage-Tolerant Electrodes:\u003c\/strong\u003e Electrodes minimize gap growth, preserving ignitability and consistent spark performance through the plug life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete 16-Piece Kit:\u003c\/strong\u003e Supplied as the full sixteen plugs required for the Ram 1500 5.7L V8, eliminating parts matching and ensuring all cylinders are refreshed at once.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis kit is best for Ram 1500 owners with the 5.7L HEMI V8 from model years shown who want a factory-quality replacement that improves ignition stability and can help with idling smoothness and throttle response.
