HPEVA DEF Injector for Dodge Ram 2500/3500/4500/5500 6.7L (2013–2020) — OEM Fit, Corrosion-Resistant, Precise Atomization

HPEVA Diesel Exhaust Fluid Injector is a direct-fit replacement nozzle for Dodge Ram 2500/3500/4500/5500 6.7L (2013–2020) built to restore proper DEF metering and reliable exhaust aftertreatment operation.

If your Ram is equipped with a selective catalytic reduction (SCR) system, the DEF injector (also called the dosing nozzle) controls the precise delivery of diesel exhaust fluid into the exhaust stream. This HPEVA unit is engineered to match original-equipment dimensions and replace OE part numbers including 04627241AD and 04627241AF. Built from corrosion-resistant materials and manufactured with laser-drilled orifices, it aims to provide consistent fluid atomization and a long service life.

How will this injector fit my Dodge Ram and which model years are covered?

This DEF injector is designed for fitment on Dodge Ram 2500, 3500, 4500, and 5500 trucks equipped with the 6.7L Cummins diesel from 2013 through 2020. Before purchasing, confirm your vehicle’s existing injector part number or compare visuals with the supplied photos to ensure correct compatibility.

• Compatible with Ram 2500/3500/4500/5500 6.7L diesel (2013–2020).
• Direct replacement for OE numbers such as 04627241AD and 04627241AF.
• Verify part number on your vehicle or consult a service manual for exact match.

What performance differences can I expect after installing this DEF nozzle?

Installing a properly functioning DEF injector restores correct fluid dosing and atomization, which helps the SCR system perform as intended. While it does not change engine output, proper metering supports efficient aftertreatment operation and helps avoid fault codes related to DEF delivery.

• Improves DEF atomization for consistent dosing.
• Helps reduce DEF-related diagnostic trouble codes (DTCs) caused by faulty injectors.
• Contributes to consistent exhaust aftertreatment performance.

Is installation difficult and what should I expect during replacement?

The HPEVA injector is manufactured to the same basic mounting and connection layout as OEM units, enabling a relatively straightforward swap. Typical installation requires basic hand tools, careful handling to avoid contaminating the nozzle, and a short calibration or system bleed procedure on some vehicles.

• Designed for direct-fit replacement — minimal modification needed.
• Use simple hand tools; avoid dropping or contaminating the nozzle tip.
• Some models may require system checks or brief programming after installation.

What materials and manufacturing features protect longevity?

This injector is made from corrosion-resistant metals and machined with precision laser-drilled spray orifices to maintain consistent spray patterns and resist clogging. The robust construction intends to withstand DEF’s corrosive properties and the thermal environment of the exhaust system.

• Wear-resistant materials for extended service life.
• Laser-drilled injection holes for precise atomization.
• Built to resist DEF corrosion and exhaust heat exposure.

Who is this for: This HPEVA DEF injector is aimed at owners and technicians maintaining Dodge Ram 2500 through 5500 trucks (6.7L Cummins) from 2013–2020 who need an affordable, OE-compatible replacement for failed or leaking DEF dosing nozzles. It suits professional shops and DIY mechanics who can verify OEM part numbers and perform a straightforward installation and system check.
