EGR Block-Off Kit

Mitsubishi Delica L300 & L400

4D56 & 4M40 Turbo Diesel Engines

This EGR Block-Off Kit is designed for Mitsubishi Delica L300 and L400 models equipped with the 4D56 or 4M40 turbo-diesel engines. Blocking the EGR system helps reduce intake soot buildup, improve throttle response, and may reduce excessive black smoke under load.

The exhaust block-off plate is pre-tapped with 1/8” NPT threads, allowing for optional installation of an EGT (Exhaust Gas Temperature) gauge.
