How much does it cost to replace spark plugs in a Dodge Durango?
Roughly $200–$900 for a typical gas-engine Durango, with price depending on engine type, local labor rates, and whether you go through a dealer or an independent shop. Diesel Durangos use glow plugs instead of spark plugs and have different costs.
What influences the price
The total cost to replace spark plugs on a Dodge Durango is affected by several factors, including the engine type, labor rate in your area, whether you choose a dealership or an independent repair shop, the type of spark plugs used (copper, platinum, or iridium), and whether any related work (such as replacing ignition coils or gaskets) is needed during the service.

Independent shops usually offer lower labor rates than dealerships, and opting for aftermarket plugs can reduce parts costs, though some owners prefer OEM plugs for warranty or performance reasons.
