High-quality EGR and DPF delete kits use：

· CNC-machined aluminum 
· Stainless steel plates
· High-temp silicone TIG-welded piping
· Avoid extremely cheap kits with thin plates or poor welds—they often leak.

Modern diesel engines need tuning after deleting emissions components. Make sure your tuner supports your specific engine year.

When buying delete kits, check your tuner supports:

· EGR Delete
· DPF Delete
· DEF Delete
· CEL clearing
· Speed limiter adjust
· Transmission tuning (for some platforms)
