EcoDiesel Fitment by Generation

Model Years Platform Engine Notes
2014-2019 Ram 1500 / Jeep Grand Cherokee Original EcoDiesel VM Motori 3.0L V6. Our Grand Cherokee listings cover 2014-2018. NHTSA recall records list diesel builds through 2020, so confirm by VIN.
2020-2023 Ram 1500 Updated EcoDiesel Stellantis calls it the third-generation EcoDiesel. New turbocharger, revised EGR system, larger SCR system

Always confirm your exact build date and VIN before ordering, because component layouts can vary within a model range. Jeep also sold the 3.0L EcoDiesel in the Wrangler and Gladiator through the 2023 model year. This guide does not cover them, so do not assume a newer Jeep is a match. If your setup is a match for this platform, our EcoDiesel delete kits collection is built specifically around Ram 1500 and Grand Cherokee fitment, not generic 3.0L applications.

The EcoDiesel Emissions System

How the 3.0L Layout Differs From a Heavy-Duty Platform

Heavy-duty trucks like the 6.7L Power Stroke or 6.7L Cummins have larger aftertreatment systems built around towing loads and longer duty cycles. The EcoDiesel V6 is a smaller-displacement engine packaged into a half-ton frame, which means the DPF, DOC, and SCR components sit in a tighter engine bay with less thermal margin.

DPF, DOC, SCR and DEF on the EcoDiesel

The Diesel Particulate Filter (DPF) traps soot and burns it off during regen. The Diesel Oxidation Catalyst (DOC) sits ahead of the DPF and helps manage exhaust temperature for that burn cycle. The Selective Catalytic Reduction (SCR) system uses Diesel Exhaust Fluid (DEF) injected into the exhaust stream to reduce NOx output. On the EcoDiesel, these three systems work together in a compact housing, and a fault in one part can set codes that look like a problem in another. Diagnose before you buy parts. Owners dealing with repeat DPF faults often start by looking at DPF delete options built for their exact generation.

EGR Cooler and Valve

The EGR system recirculates a portion of exhaust gas back into the intake to lower combustion temperatures. On the EcoDiesel, the EGR cooler is a documented wear point. Carbon buildup restricts flow over time, which can trigger reduced power, rough idle, or check engine lights tied to EGR flow codes. On 2014-2019 Ram 1500 trucks, the factory cooler is also the subject of a federal safety recall, covered below. This is why the EGR cooler is the most common starting point for owners researching EcoDiesel EGR delete kits.

For a deeper breakdown of EGR-specific failure points and repair costs, see our EcoDiesel EGR delete kit guide.

Check Open Recalls Before You Spend Money

Three federal safety recalls cover parts on these engines. Run your VIN through the NHTSA recall lookup first, because dealers perform recall repairs at no cost to the owner.

  • EGR cooler (NHTSA 19V757, Stellantis VB1): about 108,000 Ram 1500 and 1500 Classic trucks, 2014-2019. The factory cooler can crack from thermal fatigue and let vaporized coolant into the EGR system. NHTSA lists a fire risk. The remedy is a replacement cooler.
  • High-pressure fuel pump (NHTSA 22V406, Stellantis Z46): about 138,600 Grand Cherokee (2014-2020) and Ram 1500 (2014-2019) vehicles. The Bosch CP4.2 pump can fail and send debris through the fuel system, causing fuel starvation and a loss of drive power. The remedy is a new pump and inspection of related parts.
  • Crankshaft tone wheel (NHTSA 20V475, Stellantis W58): about 58,000 Ram 1500 (2014-2018) and Grand Cherokee (2014-2016) vehicles. The tone wheel can delaminate and stall the engine. The remedy is a software update.

A delete kit does not touch the fuel pump or the crankshaft hardware, so have a dealer complete any open recall of that kind first.

Why EcoDiesel Owners Look at Delete Kits

Regen Frequency on Short-Trip Driving

Ram 1500 EcoDiesel and Grand Cherokee owners frequently use their vehicles for daily driving, short commutes, and errands rather than long highway hauls. That driving pattern doesn't get the exhaust hot enough for a full passive regen as often as the system needs, which pushes the truck into active regen more frequently.

DEF and SCR Faults

DEF system faults are one of the most common complaints on this platform. A failing DEF heater, a clogged DEF injector, or a NOx sensor drifting out of range can all trigger derate conditions that limit power and speed until the fault clears.

Cost of OEM Aftertreatment Repair

A full DPF or SCR replacement on the EcoDiesel platform is a significant repair bill, especially once labor is included. Check coverage before you compare a delete kit against a dealer quote. 2014-2016 Ram 1500 and Grand Cherokee EcoDiesels in the Stellantis (FCA) emissions settlement received an extended warranty on the parts and systems affected by the emissions software update. It runs up to 10 years or 120,000 miles from original sale, or 4 years or 48,000 miles from the update, whichever gives more coverage, and it transfers to later owners. Aftermarket exhaust, EGR, and tuning changes can affect coverage, so ask a dealer first.

If your truck is out of coverage and facing repeat aftertreatment repairs, a matched kit for off-road use where permitted is one option to compare against ongoing service costs. For a full walkthrough of regen frequency, DEF faults, and what a complete removal involves, read our EcoDiesel DPF delete guide.

What's in a Complete EcoDiesel Delete Kit

A complete kit for this platform generally includes:

  • Delete pipe: replaces the factory DPF and DOC housing with a straight-through pipe section
  • EGR delete components: block-off plate or cooler bypass hardware to eliminate the EGR flow path
  • DPF delete components: hardware and gaskets specific to removing the particulate filter housing
  • Tuning requirement: the ECU needs to be recalibrated to reflect the removed hardware and to prevent fault codes

Check before ordering: confirm whether the listing you're viewing includes tuning or whether tuning is sold separately. Without a matching tune, check engine lights and drivability problems may occur on a Ram 1500 or Grand Cherokee.

For this platform, EGR delete kits and DPF delete kits are typically sold separately rather than bundled into one all-in-one kit the way some heavy-duty platforms are packaged. If you only need a pipe section rather than a full kit, standalone delete pipe options are available. Compare all three before deciding what your build needs.

Generation Differences: 2014-2019 vs 2020-2023

The 2014-2019 and 2020-2023 engines share the same displacement and V6 layout, but Stellantis changed a lot for 2020: a new turbocharger, a revised EGR system, redesigned pistons, and an SCR system 50 percent larger with a new oxidation catalyst. Delete pipe and EGR components built for 2014-2019 trucks are not always a match for 2020-2023 vehicles.

If you’re shopping for a 2014-2018 Ram 1500 or Grand Cherokee, our 2014-2018 Ram 1500 and Jeep Grand Cherokee EGR delete kit is built specifically for that configuration. Grand Cherokee owners in that same year range can also review the 2014-2018 Jeep Grand Cherokee DPF and EGR delete kit, which pairs both systems for that specific platform.

If you're shopping for a 2020 or newer Ram 1500, confirm the listing specifically states 2020-2023 EcoDiesel compatibility. Don't assume a 2014-2019 part will bolt up just because the engine size matches.

Install Expectations

Difficulty and Time on a Half-Ton Platform

Compared to a Super Duty or 2500/3500 heavy-duty truck, the EcoDiesel's engine bay is tighter and access to some fittings is more limited. Installation difficulty runs moderate for an experienced DIY owner with basic hand tools, a torque wrench, and a lift or ramps. Owners without prior exhaust or emissions system experience should plan for a full day or consider professional installation, particularly for the tuning step, which requires a compatible handheld or laptop-based tuning device matched to the ECU. If your kit calls for a matching delete pipe, the 3-inch EcoDiesel delete race pipe built for the 2014-2018 Grand Cherokee is a common pairing for that year range.

Tuning Access on 2018 and Newer Trucks

Stellantis added a Security Gateway Module (SGW) to most 2018 and newer vehicles, including the Ram 1500 and Grand Cherokee. It sits between the OBD-II port and the vehicle network and blocks most programming commands from aftermarket tools unless the tool is authorized or the gateway is unlocked with extra hardware. Ask your tuning provider how your exact year gets flashed, and what hardware that takes, before you order.

Legal and Compliance Notes

You are responsible for confirming federal, state, and local requirements before purchase and installation. These points apply to every EcoDiesel build:

  • The federal Clean Air Act prohibits removing or disabling emissions controls on a certified motor vehicle, and it prohibits selling parts whose principal effect is to defeat them.
  • EPA's position is that a certified vehicle must stay in its certified configuration even when used only for competition. An off-road or race label does not create an exemption by itself.
  • In January 2026 the Department of Justice stopped pursuing criminal charges for certain onboard-diagnostic tampering cases. The Clean Air Act did not change, and EPA civil enforcement continues.
  • EPA's current penalty table lists civil penalties of up to $5,911 per violation for tampering by an individual, adjusted for inflation.

FAQ

Is the EcoDiesel worth modifying?

It depends on your truck's exact year, configuration, and use. Start with recall and warranty coverage, because a covered repair costs you nothing. If you still face repeat DEF faults, frequent regen from short-trip driving, or a costly aftertreatment quote, a kit built for the correct year and matched with the right tune is one option for off-road use where permitted.

Do I need a tuner if I delete my EcoDiesel?

Yes. Removing DPF, DOC, or EGR hardware without a matching tune can trigger check engine lights and cause drivability issues. Treat tuning as a required part of the build, not an optional add-on.

Can I install an EcoDiesel delete kit myself?

Most owners with basic mechanical experience and the right tools can complete the hardware install. Tuning requires a compatible device and some familiarity with the process. If you're not comfortable with either step, professional installation is the safer route.

Are EcoDiesel delete kits legal for road use?

Do not assume they are. Some products are intended only for off-road, race, or non-public-road use where permitted. See the Legal and Compliance Notes above.
