Replace the intake in your GM 6.6L Duramax today with the Wehrli Custom Fab WCF100194-FB 4" Intake Kit W/Air Box - Flat Black from GAP. 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.

All aluminum construction features large diameter 4" piping with smooth aerodynamic bends to improve intake air velocity, 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.

Nice foam latex pillow. A little thicker than I wanted, but has improved my sleep quality

Just what we were looking for.
Been buying these latex foam pillows for years. Definitely less firm due to it being “extra soft”. Soft and still somewhat supportive. Is not hot either. So glad I can still buy these pillows.
