*WCFab 2001-2004 GM LB7 6.6L Duramax 4" Stage 1 Intake Kit with Air Box*
This high-flow, fabricated aluminum intake pipe and air box enclosure with dry filter assembly replaces the restrictive plastic factory parts on your diesel for improved engine performance.
The all-new design significantly increases airflow to your turbo, producing more horsepower and torque, quicker throttle response, and cooler intake temperatures by drawing cold air through the inner fender. The all-aluminum construction features large-diameter 4" piping with smooth aerodynamic bends to improve intake air velocity and volume, providing a more aggressive engine and turbo sound during acceleration.
High-quality hardware, silicone boot, seals, and stainless steel T-bolt clamps ensure optimum durability and ease of installation. The removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with the included hydrophobic pre-filter cover, helping keep your MAF sensor, turbo, and engine airways contaminant-free.
Includes the high-flow 3.5 in. Turbo Intake Horn, which removes restrictions in the OEM setup to improve turbo spool and top-end power. This high-flow 3.5 in. horn is fully compatible with both OEM and upgraded drop-in IHI-style turbochargers.
The full assembly is finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck.
Supersedes WCF100636 and replaces GM part numbers: 19201277, 25345138, 21993711, 15076901.
