A Plus Auto Fuel Injectors for V8 HEMI 5.7L - Pre‑installed O‑Rings & OEM Fit, Tested Flow

A Plus Auto replacement fuel injectors engineered for V8 HEMI 5.7L engines provide measured spray patterns, tested flow rates, and a one-year unlimited-mile warranty for reliable fuel delivery.

These injectors are built to match OEM fit and function for many Chrysler, Dodge, Jeep and Ram V8 models, including 5.7L HEMI applications and select 6.1L / 6.4L engines. Each unit is precision-tested for leakage, atomization, spray cone and flow uniformity so you can restore consistent fueling performance after wear or contamination affects original injectors. The set includes pre-installed O-rings and basket inlet screens to reduce debris entry and support long-term operation.

Which vehicles are these injectors compatible with?

These A Plus Auto injectors are specified for a broad list of Chrysler, Dodge, Jeep and Ram V8 models across several years. Compatibility covers common 5.7L HEMI installs plus selected 6.1L and 6.4L models — check exact model-year fitment before ordering.

• Chrysler: 300 (2010–2016 5.7L, 2018 5.7L; 2005–2010 6.1L), Aspen (2009 5.7L)
• Dodge: Challenger (2008–2016 across 5.7L & 6.1L), Charger (2006–2018 across 5.7L & 6.1L), Durango (2011–2018 5.7L), Magnum (2006–2008 6.1L)
• Ram: 1500/2500/3500 variants (2009–2018 depending on model and engine), plus specific 6.4L 3500 fitment in 2015

How do these injectors perform compared with OEM parts?

A Plus Auto injectors are engineered to match key OEM characteristics: flow rate, spray angle and electrical resistance. Performance testing includes leakage, blockage, atomization and nozzle uniformity to ensure close functional parity with factory components.

• Dynamic flow: approximately 127.0 ±5% ml/min
• Static flow: approximately 301.0 ±5% ml/min
• Spray cone: ~15° ±1° and coil resistance ~12.5 ±1Ω
• Leakage ≤0.8 kPa/25s and pre-installed O-rings for seal reliability

What installation and maintenance details should I know?

Installation follows standard fuel rail injector procedures; always relieve fuel pressure and follow vehicle-specific service instructions. The injectors include inlet basket filters to help reduce debris entry, but cleaning fuel system components and replacing inline filters prior to installation improves lifespan.

• Includes pre-installed O-rings and basket filter at the inlet
• Replaces part numbers: FJ732, FI11369S, 05037479AA, RL037479AA, TLF79AB52LB8
• Recommended: inspect rails, seals, and fuel filters during replacement
• Installation best practice: torque rails per factory spec and perform a leak check

What warranty and support come with the product?
