Which vehicles will this injector fit?

This injector is designed for V6 3.7L engines across multiple model lines and years. Compatibility covers many Dodge, Jeep, Mitsubishi and Ram applications, but always verify fitment before purchase.

• Compatible Dodge models: Dakota (2004–2010; 2011 V6 3.7L), Durango (2004–2009), Nitro (2007–2011), Ram 1500 (2004–2010; 2011–2012)

How does this injector affect engine performance and fuel economy?

The injector’s 4-hole nozzle and controlled flow rates help produce a finer, more even fuel spray for improved combustion consistency. That can support smoother idling, more responsive throttle behavior and potentially better fuel use when the rest of the fuel system is in good condition.

• Dynamic flow: 110.0 ±5% ml/min; static flow: 221.0 ±5% ml/min for consistent delivery
• 4-hole spray pattern improves atomization versus single-hole alternatives
• Pre-installed O-rings and basket inlet filter reduce leakage and contamination

What are the electrical and sealing specifications I should know?

This injector uses a two-terminal blade connector with a male terminal and a coil resistance tuned for factory-style operation. Tight sealing and leak limits are specified to help avoid drivability issues caused by fuel pressure loss or air intrusion.

• Terminal quantity: 2; terminal type: blade; terminal gender: male
• Coil resistance: 12.5 ±1 Ω for proper drive compatibility
• Leakage spec: ≤ 0.8 KPa/25s; pre-installed O-rings help ensure a secure seal

What replacement parts and warranty information are included?

This product is sold as a single injector intended to replace several common OEM numbers — confirm the specific required part for your cylinder. A Plus Auto backs the injector with a practical warranty and customer support if fitment or performance questions arise.

• Replaces: FJ474, 53032701AA, 0280158020 — verify against your vehicle
• Sold as a single injector; check whether you need multiple units for a full engine service
• 1-year, unlimited-mile warranty and access to A Plus Auto customer support
