EGR delete, also known as EGR bypass, is a modification that completely removes or disables the exhaust gas recirculation system in a diesel engine.
The EGR (Exhaust Gas Recirculation) system works by reintroducing some exhaust gases into the intake system to reduce emissions. However, over time, EGR systems often experience problems such as carbon buildup, blockages, overheating, and reduced power. This is why people remove EGR systems.
EGR delete often refers to removing the following EGR-related components:
Users considering purchasing an EGR removal kit often inquire about performance improvements, cost, and legality. Below, we've outlined the pros and cons for your reference.
Our Position: These kits offered by SuncentAuto are only for off-road, racing, or agricultural use. We strongly recommend that you familiarize yourself with and comply with all applicable local Environmental Protection Agency (EPA) and state regulations before purchasing or installing any aftermarket products.
Based on SuncentAuto's long-term real-world testing across multiple platforms including Powerstroke, Duramax, and Cummins, we have identified the most significant performance improvement after removing EGR. The following data is derived from real-world vehicle testing and typical user feedback.
| Item | Before EGR Delete | After EGR Delete (SuncentAuto Test Data) |
| Fuel Economy (MPG) | Baseline MPG | +5% MPG improvement — cleaner airflow and no exhaust recirculation |
| Fuel Cost Over 300,000 Miles | Requires periodic EGR valve & cooler cleaning / replacement | >$8,000 saved (no cleaning, no replacing, no clog-related failures) |
| Throttle Response | Noticeable turbo lag & delayed acceleration | 0.3s faster throttle response |
| Exhaust Note | Restrained airflow, softer exhaust tone | More explosive & smoother exhaust flow, no extra “buzz” |
| Engine Temperature – Pre-EGR Area | Higher coolant temperature due to hot exhaust recirculation | 20°C drop, improved coolant circulation |
| Engine Bay Temperature | Heat accumulation around EGR & intake area | 7°C lower, better overall thermal stability |
| DPF Reliability | Higher soot load → higher DPF clog risk | Reduced DPF failure risk, cleaner burn & fewer regenerations |
| Component Lifespan | Intake, turbo, and sensors exposed to carbon buildup | Extended lifespan due to carbon-free airflow |
We offer comprehensive EGR removal solutions to meet the specific needs of major diesel engines. You can find the right kit for you using our vehicle selector or by contacting customer service.

EGR delete refers to removing the original EGR system, preventing exhaust gas recirculation from entering the intake system. This can improve intake volume, reduce carbon buildup, lower exhaust temperature, and improve fuel efficiency and horsepower.
No. In most states in the United States, using an EGR removal kit on a highway vehicle is illegal. SuncentAuto only sells products for off-road/off-road use.
Yes. After removing the EGR, the ECU will still monitor the EGR valve's operation as usual. Therefore, ECU tuning is needed to disable EGR control and suppress fault codes, preventing the engine malfunction indicator lamp from continuously illuminating.
Yes. User feedback indicates a 5% to 20% improvement in fuel efficiency after installation, especially when the DPF and CCV are removed simultaneously.
Yes. Removing the EGR eliminates emissions restrictions, which improves cylinder airflow and can increase horsepower by 20-50.
You can use our vehicle adapter, check the product details page for a complete compatibility table, or seek support from our professional customer service.
Generally, EGR removal kits range in price from $100 to $600, depending on the brand, materials, engine, etc. SuncentAuto's overall pricing is very reasonable and offers excellent value. It's recommended to compare prices from different brands before purchasing.
You will need to physically remove the EGR system, then install a removal kit, and finally disable EGR monitoring by tuning the vehicle's ECU.
Yes. Our kits include detailed installation instructions and professional customer support. However, for beginners, we still recommend professional installation for best results.
This is precisely why ECU tuning is necessary. Proper tuning will permanently disable the EGR-related malfunction indicator light.
Please contact our brand's after-sales service, providing your vehicle information and the symptoms of the malfunction. We will quickly provide you with professional technical support or parts replacement service.
