Ecodiesel EGR Delete KIt

EGR (Exhaust Gas Recirculation) is designed to lower combustion temperatures by routing exhaust gas back into the intake. On the 2014–2018 3.0L EcoDiesel (FCA Lion engine), the EGR cooler and valve are notorious for clogging with carbon deposits, causing increased intake temperatures, reduced fuel economy, rough idle, and sluggish throttle response. If your Ram 1500 EcoDiesel or Jeep Grand Cherokee has started running rough or burning more fuel than usual, a faulty EGR system is often the culprit. The SPELAB EGR delete kit eliminates this problem entirely with block-off plates, a bypass pipe, and an ECM tuner to prevent fault codes.

This kit fits all vehicles equipped with the 3.0L EcoDiesel (FCA Lion engine):

• Dodge Ram 1500 EcoDiesel: 2014, 2015, 2016, 2017, 2018
• Jeep Grand Cherokee EcoDiesel: 2014, 2015, 2016, 2017, 2018
• Jeep Wrangler EcoDiesel: 2014, 2015, 2016, 2017, 2018

It does not fit gasoline-powered models, earlier Cummins/Powerstroke/Duramax platforms, or any EcoDiesel outside the 2014–2018 range. If you are unsure of your engine type, check your VIN or engine code label before ordering.

No. The included ECM tuner reprograms your engine control module to disable EGR monitoring entirely. Without the tuner, removing the EGR system would trigger multiple fault codes and likely force the engine into limp mode (reduced power for protection). The tuning component is what makes this kit street-capable after installation — it tells the ECU the EGR system simply doesn't exist, maintaining full driveability and power output without warning lights.

EcoDiesel owners commonly report 1–3 MPG improvement after completing an EGR delete. The gains come from eliminating the EGR valve's stuck-open and clogged states, which disrupt the air-fuel ratio and force the engine to compensate with excess fuel. Combined with improved throttle response and reduced carbon buildup, the real-world efficiency gains make a noticeable difference on highway drives. Actual results vary based on driving style, load, and whether other modifications (intake, exhaust, tuner) are added.

No. EGR delete kits are for off-road and racing use only. They are not legal on public roads in states with emissions testing, including California and any state following CARB (California Air Resources Board) standards. Installing this kit on a street-driven vehicle in these jurisdictions will result in a failed emissions test. If you live in a state without emissions inspections, local regulations may still apply. Check your local laws before purchasing — SPELAB is an aftermarket accessory provider with no affiliation to any vehicle manufacturer.

Yes. Most EcoDiesel owners with intermediate mechanical skills can complete the install in 2–4 hours using basic hand tools. The kit includes block-off plates for the EGR ports, a bypass tube for the EGR cooler, and the required ECM tuning device. The tuner is mandatory — do not attempt the delete without it, or the engine will enter limp mode. No welding is required; all connections are bolt-on. After installation, simply flash the included tune to your ECM following the step-by-step guide included in the box.
