The XDP LML EGR Blocker Plate XD170 is designed to block the Exhaust Gas Recirculation (EGR) system on your 2011-2015 6.6L LML Duramax. The EGR system recirculates exhaust gases back into your engine. During this process, carbon build-up is also deposited in your trucks intake system. After time, carbon accumulation can restrict your engine and hinder performance.

Installing the EGR Blocker Plate prevents hot exhaust gases from recirculating through your engine. Once installed, the Blocker Plate can be easily reversed returning your truck back to stock. Its slotted design reduces install time by allowing you to simply "slide" the plate in place without having to remove any major components. For off-road use only.


  • Prevents Further Soot Accumulation
  • "Slotted" Design For Easy Install
  • Simply Blocks EGR Flow, No Components To Remove
  • Easily Returned Back To Stock
Note: 2 Blocker Plates required. Installation of the XD170 will cause EGR related DTC trouble codes. Aftermarket tuning is required.
