DHD 600-101 Modified LB7 High Flow Intake Horn 01-04 Duramax Diesel
This is a modifed LB7 Duramax turbocharger air inlet tube (air horn) that we port in house. The DHD mouthpiece has a 26% larger I.D at the mounting flange. Each horn is inspected, cleaned, machined and painted. This is an economical solution for those seeking higher intake flow volume for their LB7. DHD also modifies the mounting flange holes to ease in installation. With these slotted holes the horn can be installed and removed easily if needed.
Its always best practice to replace the inlet gasket (97318441) when installing this piece.
Core: This item is NLA from GM so a core is required. Cores must be Non-California emissions to receive core credit. California emission inlets are identified by an indentation in the tube section of the mouthpiece. If you elect to not pay for the core charge the order will be held until the core is received.
