2004-2005 GM/CHEVROLET 6.6L DURAMAX HIGH FLOW TURBO INTAKE ELBOW
Unlock airflow and increase turbo performance on your 2004–2005 GM/Chevrolet 6.6L Duramax LLY with this High Flow Turbo Intake Elbow. The factory intake elbow on LLY engines is restrictive and prone to heat soak—robbing your turbocharger of critical airflow and increasing intake temps.
This upgraded elbow is precision-machined from mandrel-bent aluminum and designed to eliminate the restrictive stock bottleneck between the intercooler pipe and turbo inlet. The result is improved turbo spool-up, lower EGTs, and better throttle response—especially under heavy load or towing conditions.
Perfect for performance builds or as a smart preventative upgrade during intercooler pipe or turbo service.
What’s Included in the Kit:
-
(1) High flow turbo intake elbow (aluminum or coated steel, model dependent)
-
(1) Premium high-temp silicone coupler
-
(2) T-bolt clamps
-
Mounting hardware (if required)
This kit is compatible with OEM or aftermarket intercooler piping. Minor tuning not required but may enhance gains.
