Grab the Wehrli Custom Fab WCF100344-BB 4" Intake Kit W/Air Box - Bengal Blue from GAP for your GM 6.6L Duramax today. 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.

2X THE LOVE!
Color: Black
These are fabulous! The weight to them is perfect for tearing off a towel and not tipping. And the color/style works perfectly with our decor. Even my husband who rarely comments on anything said "I really like these!" I have one in my kitchen with regular paper towels and my laundry room with the microfiber towels. LOVE!!

Looks sleek and works great
Color: Warm Gold, Color: Warm Gold
It looks very sleek. Perfect match in color to my kitchen hardware. I was afraid it wouldn’t work as well as my old one but it actually works much better. Less pulling off more paper towels than needed. Even the extra large paper towels fit on nicely.
