A Cummins ISX EGR delete kit is generally marketed as aftermarket hardware intended to remove, block, or bypass the exhaust gas recirculation system on an ISX diesel engine. These kits may be promoted for reducing intake deposits, changing engine response, or avoiding EGR-related maintenance.
However, I can’t provide instructions for removing or bypassing the EGR system on an emissions-controlled engine. The EPA specifically identifies EGR-blocking hardware and engine calibrations that bypass EGR operation as emissions tampering/defeat-device activity.
EGR Maintenance Alternatives
For an ISX experiencing EGR problems, a better approach is to diagnose and repair the existing system. Cummins maintenance guidance includes checking the EGR system and hoses as part of routine maintenance.
Useful options include:
- EGR valve inspection or replacement
- EGR cooler inspection and cleaning
- Intake-system cleaning
- Checking EGR hoses and connections
- Diagnosing related sensors and fault codes
- Replacing restricted filters
- Using OEM or approved replacement components
Performance Options
If the goal is improved Cummins ISX performance, consider upgrades that don't disable emissions controls, such as:
- Improved air filtration
- Turbocharger maintenance or compliant upgrade
- Charge-air-system improvements
- Fuel-system maintenance
- Cooling-system improvements
- Emissions-compliant engine calibration
The EPA has taken enforcement action against companies selling EGR-delete kits and other diesel defeat devices, noting that these modifications can substantially increase pollutants such as NOx and particulate matter.
