2014 Ram 3500 Delete Kit: DPF, EGR & DEF Problems Solved

Everything you need to know about deleting the DPF, EGR, and DEF systems on your 2014 Dodge Ram 3500 6.7L Cummins — and which kit is right for your truck.

Quick Answer

The 2014 Ram 3500's 6.7L Cummins is plagued by three separate emissions headaches: a DPF that forces fuel-burning regen cycles every few hundred miles, an EGR system that clogs the intake with carbon, and a DEF system prone to dosing failures and crystallized injectors. A single all-in-one delete kit — starting at $305.99 at DPFexhaust — can be a good alternative way to deal with those headaches.

Part 1: The 3 Biggest Problems on a 2014 Ram 3500 — DPF, EGR & DEF

Spend any time on a Cummins forum or a 6.7L Ram Facebook group, and you'll hear the same complaints repeated by hundreds of owners -- they're built-in failure modes baked into the 2013–2018 emissions system by design. Here's what real 2014 Ram 3500 owners are saying.

Reddit · r/Diesel & Cummins Forum
"My 2014 3500 just hit 90,000 miles. Every 300 miles the truck goes into regen and burns fuel like it's going out of style — I watch my MPG drop from 17 to 11 during active regen. Over a year that's hundreds of dollars in extra diesel just to burn off soot the filter was never designed to handle long-term. Three shops have told me the DPF is nearing end of life. Quote for a new one: $3,200."
The Diesel Particulate Filter (DPF) Problem: The DPF on 2013–2018 6.7L Cummins trucks forces active regeneration cycles that inject raw fuel into the exhaust to burn off accumulated soot. On trucks doing heavy towing or short-trip driving, these cycles happen far more frequently than Ford/Dodge intended. The result is chronic fuel dilution of your engine oil, accelerated wear on the DPF itself, and real-world fuel economy that drops by 4–7 MPG during active regen. A clogged DPF on a 2014 Ram 3500 can cost $1,500–$3,200 to replace.
Facebook · 2013–2018 Ram Cummins Owners Group
"Popped the intake manifold off my 2014 at 115k miles for a turbo upgrade and the whole thing was caked in a thick layer of black carbon. Took hours to clean it out. The EGR cooler had been leaking coolant into the intake on top of that. Mechanic said it's one of the most common failures on these trucks. I didn't even know the EGR valve could cause this much damage."
The Exhaust Gas Recirculation (EGR) Problem: The EGR system on 6.7L Cummins routes a portion of exhaust gases back into the intake to reduce combustion temperatures and NOx emissions. The problem is, it also routes hot exhaust carbon and oil vapor directly into your intake manifold, building up a thick carbon layer on the intake valves that degrades performance over time. When the EGR cooler cracks, coolant leaks into the intake, causing overheating and white smoke. EGR cooler replacements at the dealer run $800–$1,800 in parts alone.
RamForumZ & Diesel Truck Resource Forum
"Truck threw a DEF quality sensor code at 60k miles. Then the DEF pump failed. Then the dosing injector got clogged with crystallized urea. Dealer quote: $4,100 for the entire DEF system rebuild. I'm spending more on DEF repairs than on actual fuel. This is the most frustrating truck I've ever owned from a maintenance standpoint."
The Diesel Exhaust Fluid (DEF) Problem: The DEF dosing pump can fail, the injection nozzle might be clogged with crystallized urea (especially in cold weather), and the DEF quality sensor triggers false codes that derate engine's power. In some cases, the truck enters limp mode until the DEF system is serviced. With DEF priced at $7–$10 per gallon and a tank that holds 5–7 gallons, ongoing DEF costs add hundreds of dollars per year on top of expensive repairs.

Part 2: Non-Delete Ways to Manage Your 2014 Ram 3500's DPF, EGR & DEF Problems

There are steps you can take to reduce the severity of each system's problem. These approaches manage symptoms but don't eliminate the root cause, which is the emissions hardware itself.

Problem Maintenance Fix Estimated Cost
DPF Clogging & Frequent Regen Drive at highway speeds for 30–45 minutes regularly to allow passive regen. Check and replace the DPF pressure sensor — a faulty sensor can trigger false regen events. $150–$400
EGR Carbon Buildup & Cooler Leaks Have the EGR valve and cooler inspected at every major service. Replace the EGR cooler proactively before it cracks. $300–$1,800
DEF Failures & Crystallization Use high-quality DEF only. In cold climates, park indoors to prevent freezing-thawing cycles that concentrate urea. Run the truck regularly to keep the DEF system cycling and prevent crystallized deposits in the dosing lines. $7–$15/gallon of DEF
⚠️ The Bottom Line on Maintenance: Every dollar spent on maintaining the stock 2014 Ram 3500 emissions system is a recurring cost. The DPF, EGR, and DEF systems were engineered to meet emissions standards. If your truck is past 80,000 miles and you've already spent money on any one of these repairs, a delete kit might be an alternative on your radar.

Part 3: The Delete Solution — DPF/DEF/EGR All-in-One Kits & DPF/EGR Delete Kits

Removing the DPF, DEF, and EGR systems from your 2014 Ram 3500 will help with three problems all at once. Without the DPF forcing regen cycles, your engine runs on its actual tune. Without EGR, your intake stays clean and your engine burns cleaner. Without DEF, you don't need to spend on urea fluid or DEF system repairs anymore. DPFexhaust offers two tiers of solutions: full all-in-one kits with tuner hardware and software, and standalone DPF/EGR delete kits for trucks that already have their own tuner.
