Update the intake and air box on your GM 6.6L Duramax today with the Wehrli Custom Fab WCF100344-FTB 4" Intake Kit W/Air Box Texture Black from GAP. This high-flow, fabricated aluminum intake pipe and air box enclosure with dry filter assembly replaces your diesel's restrictive plastic factory parts for improved engine performance.

All aluminum construction features large diameter 4" piping with smooth aerodynamic bends to improve intake air velocity and volume and provide 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 an included hydrophobic pre-filter cover to help keep your MAF sensor, turbo, and engine airways contaminant-free. The critical ram air duct seal has been moved to the bottom of the hood for a clean engine compartment appearance.

Filters well but causes air flow restrictions
Very thick and does filter well however it is so thick it actually blocks quite a bit of air flow

Did not disappoint!
Perfect Fit: Bolted right up to the engine block without any shimmying or modification needed.
Strong Crank: The motor sounds powerful and turns the engine over significantly faster than my old, dying unit. Once hooked up, the car fired up instantly on the first turn of the key. No grinding, no clicking, just a smooth, high-torque start.
Price: A lot more cheaper then your average auto parts stores.
Build Quality: The solenoid connections are solid and the threads were clean.
Packaging: The box arrived on time but a bit beat up, but the starter itself was well-protected in bubble wrap and undamaged.
