Exergy 04.5-07 Dodge Cummins (Late 5.9) New 100% Over Injector (Set of 6)

This engine parts collection covers oil catch cans, thermostats, thermostat housings, radiator components, coolant accessories, engine covers, fuse box covers, cap covers, throttle bodies, supercharger pulleys, idler pulleys, tensioner pulleys, and engine bay dress-up parts for trucks, SUVs, muscle cars, boosted builds, high-horsepower street cars, and performance vehicles that need better reliability, cooling, airflow, oil control, and under-hood styling. The collection is particularly strong for Dodge Challenger, Charger, Durango, Jeep Grand Cherokee Trackhawk, and Ram TRX platforms running 6.2L Hellcat, 6.4L HEMI, and 5.7L HEMI engines, where oil catch can and cooling upgrades address known OEM weaknesses in the PCV and thermal management systems. Import performance platforms including GM LS-based builds, Chevrolet Camaro, and Corvette applications are also represented through Mishimoto, CSF, and ZPE GripTec product lines. Builders who invest in engine bay organization and reliab...

Exergy Performance is a diesel fuel system specialist focused on high-output injection components for Cummins, Duramax, and Power Stroke diesel platforms, producing fuel injection pumps, injectors, injection lines, lift pumps, and supporting fuel system hardware that addresses the OEM injection system's limitations at elevated power levels. Diesel truck owners who push beyond the factory tune with larger turbochargers, performance camshafts, and aggressive fueling strategies quickly reach the capacity ceiling of the stock injection system, and Exergy provides the fuel system architecture that allows the engine to support those power levels safely and consistently. The Duramax LML CP3 conversion kit, which replaces the problematic CP4.2 high-pressure pump with the more robust CP3 design proven in earlier Duramax generations, is one of Exergy's most important product solutions for preventing the catastrophic fuel system contamination failure that affects stock LML and L5P trucks runni...

Fuel injector connectors are the electrical interface between the engine wiring harness and each individual fuel injector solenoid, carrying the precision pulse-width-modulated signal from the ECU that controls injection timing and duration. Connector failure, corrosion, or poor terminal contact causes intermittent misfires, rough idle, and lean conditions that are frustratingly difficult to diagnose without testing each injector circuit individually. Replacing damaged or corroded injector connectors with new pigtail harnesses using factory-grade terminals restores clean electrical contact and eliminates ghost faults that confound standard scan tool diagnostics. Builders doing engine swaps or injector upgrades also rely on connector pigtails to adapt factory harnesses to new injector styles without permanently altering the original wiring. Popular Upgrades Top-selling injector connectors include Delphi and Bosch OEM-spec EV6 connector pigtails for late-model GM, Ford, and Chrysler E...

Fuel injectors are the precision metering devices at the heart of every modern electronic fuel injection system, responsible for atomizing fuel into a fine mist at exactly the right moment, duration, and spray angle for complete combustion. As injectors age, internal deposits and solenoid wear cause flow rate deviation, tip coking, and spray pattern degradation that result in rich or lean cylinder conditions, rough idle, elevated emissions, and reduced fuel economy. Selecting the correct replacement or performance injector requires matching the flow rate, impedance, connector type, and spray angle to your specific engine and fuel system configuration. From factory-replacement units restoring a daily driver to high-impedance Injector Dynamics sets supporting four-figure horsepower builds, this collection covers the full range of fuel injector needs. Popular Upgrades Top-selling fuel injectors include Bosch OEM-replacement and remanufactured injectors for high-volume domestic and impo...

Diesel fuel injectors operate at extreme precision, delivering metered bursts of fuel at pressures exceeding 30,000 PSI in common-rail systems while maintaining spray patterns accurate enough to produce complete combustion without excess particulate emissions. On platforms like the 6.7L Cummins, 6.6L Duramax, and 6.7L Powerstroke, worn injectors cause visible black smoke under load, reduced fuel economy, rough idle, and eventually a no-start condition as solenoid wear prevents full needle lift. Rebuilding or replacing diesel injectors with OEM-spec or upgraded aftermarket units is one of the highest-impact repairs on a high-mileage diesel truck, often restoring performance to near-new levels. Matching injectors precisely to your engine platform and boost level ensures optimal atomization and combustion efficiency. Popular Upgrades Top-selling diesel injectors include Bosch factory-reman units for the 6.6L Duramax LB7 and LMM, Industrial Injection performance injectors for the 5.9L a...
