Caterpillar EGR Delete

The EGR system recirculates part of the exhaust gases to help reduce emissions. Over time, this process may contribute to carbon buildup in some Caterpillar diesel engines. These deposits can affect engine operation and increase maintenance needs.

Diesel Spec provides EGR delete solutions exclusively for off-highway applications. Our services cover several Caterpillar engines, including the 3126, C7, C9, C13, C15 and C18 series. Review the list below to check your engine’s compatibility.

Diesel Spec supports more than 30 Caterpillar diesel engine configurations. Compatibility depends on the engine model, production year and tuning requirements. Contact our team for a complete assessment of your application.

What are the potential benefits of Caterpillar EGR delete tuning?

Potential benefits depend on the engine, its condition and the selected calibration. For compatible off-highway applications, tuning may reduce issues associated with EGR-related carbon buildup.

• Improved engine response: A compatible calibration may improve throttle response and overall drivability.
• Reduced carbon buildup: Preventing exhaust gases from recirculating may help limit deposits in the intake system.
• Simplified maintenance: Addressing EGR-related operating issues may reduce certain repair needs over time.
