Bosch Spark Plug P/N:9612
Bosch 6734 spark plug for the 2009-2023 Jeep Grand Cherokee V8 5.7L and other vehicles ignites the air-fuel mixture in each cylinder. This Bosch OE Fine Wire single platinum plug is engineered to meet Original Equipment specifications for platinum spark plugs.
Its platinum firing pin needs up to 24% less voltage to ignite and gives up to 2 times longer life than standard copper spark plugs. Hard starting, a rough idle or a misfire can mean the plugs are worn. Before you replace them, rule out the ignition coils, wiring and fuel delivery, because a misfire has more than one possible source.
The vehicles it fits include the 2009-2023 Jeep Grand Cherokee V8 5.7L and the 2011-2024 Ram 1500 V8 5.7L, and it is also a spark plug for the 2009-2023 Dodge Charger V8 5.7L. These V8 5.7L engines take 16 plugs, and this listing is one plug. Open the "Vehicles it fits" section to check your exact model and engine.
