RLP Fuel Injectors for 3.6L Pentastar Engines — 2011–2017 Chrysler/Dodge/Jeep/Ram Compatible, 4-Hole Set, OE Replacement

RLP replacement fuel injectors 0280158233 (replaces 05184085AC) are a tested 4-hole injector set engineered to restore proper fueling for 3.6L Chrysler, Dodge, Jeep and Ram engines from 2011–2017.

These RLP injectors deliver the spray pattern, flow rate and electrical resistance specified for many 3.6L Pentastar engines so you can correct misfires, rough idle and reduced power caused by worn or leaking injectors. Each unit is built from corrosion-resistant materials, preinstalled O-rings and a basket inlet filter, and shipped as a full set that fits a long list of Chrysler Group vehicles. They are bench-tested for flow, leakage and electrical resistance, and covered by a 12-month warranty.

How do these injectors match OE performance?

RLP engineered the injectors to meet the original equipment specifications for flow, spray cone and coil resistance. That alignment minimizes drivability issues and helps the engine management system maintain correct air/fuel ratios.

• Static flow rate: 207.8 ±4% g/min to match factory delivery.
• Spray pattern: 15° ±1° cone angle for proper atomization.
• Coil resistance: 12 ±1 Ohms for compatible electrical load.
• Four-orifice orifice for even fuel distribution across the combustion chamber.

What build features improve durability and sealing?

These injectors use high-alloy steel and high-temperature plastics to resist corrosion and thermal cycling in the engine bay. Preinstalled heat-resistant O-rings and a verified sealing specification reduce the risk of external leaks.

• High-alloy steel body for corrosion resistance under fuel exposure.
• Heat-resistant O-rings installed to maintain long-term sealing.
• Basket-style inlet filter to protect internal passages from debris.
• Sealing performance tested at 0.4 MPa with leakage under 3 ml/min.

Which vehicles and part numbers are these compatible with?

The set replaces OE numbers 0280158233 and 5184085AC and fits a wide range of Chrysler Group 3.6L engines built between 2011 and 2017. Always confirm fitment for your specific model and trim before ordering.

• Compatible models: Chrysler 200/300, Town & Country (selected years), Dodge Challenger/Charger, Avenger, Durango, Grand Caravan, Journey.
• Jeep fitment: Grand Cherokee and Wrangler (selected model years).
• Ram fitment: ProMaster 1500/2500/3500 (selected years).
• Replaces OE: 0280158233, 05184085AC (5184085AC).

What quality checks and warranty cover these injectors?

Each injector is tested on the bench for flow, spray pattern, leakage and electrical resistance before shipment. The product includes a 12-month warranty and a refund or replacement policy if the part fails under normal use.

• 100% flow and leakage testing for every injector.
• Spray and resistance verification to confirm uniform delivery.
• 12-month warranty and customer support for defective units.
• Significant cost savings versus dealer-priced replacements.

Who this is for: Automotive owners and independent mechanics who need a cost-effective, factory-spec replacement injector set for 3.6L Pentastar engines. If your vehicle shows cylinder misfire codes, rough idle, reduced fuel economy, or loss of power and it uses the compatible part numbers and model years listed, these RLP injectors provide a tested aftermarket option to restore reliable fueling while saving on dealer costs. Always verify exact fitment for your make, model and trim before installation.
