A pre-matched set of eight 550cc/min fuel injectors engineered for direct replacement on Chrysler 5.7-liter, 6.1-liter, and 6.4-liter Hemi V8 engines.

Dropped in without harness adapters, these units utilize an EV14 universal pin configuration to ensure seamless electrical communication with your existing engine control module. Each injector in the batch has been flow-tested and balanced to deliver identical atomization across all eight cylinders, eliminating the rough idle, hesitation, and incomplete combustion that occur when mixing degraded OEM units with new replacements.

Designed to mount directly onto the intake manifold plenum of the following platform vehicles:

• Dodge Challenger RT / SRT8 Hemi 5.7L, 6.1L, 6.4L (2008–2024)
• Dodge Charger RT / SRT8 Hemi 5.7L, 6.1L, 6.4L (2006–2024)
• RAM 1500 and 2500 Hemi 5.7L, 6.1L (2003–2015)

While built for performance applications, the 550cc/min rating serves as a precise flow baseline for restoring factory displacement metrics. The calibrated valve seat geometry maintains proper fuel spray cone patterns at both idle and wide-open throttle conditions. This configuration preserves safe air-to-fuel ratios during daily driving while giving technicians reliable headroom when supporting upgrades to the induction or exhaust system.

Installation requires standard mechanical hand tools, a fuel rail clamp tool, and fresh O-rings lubricated with engine-safe assembly fluid before seating into the upper port. Pair the hardware swap with a standard tune recalibration to optimize ignition timing and injector pulse width parameters.
