Find the Wehrli Custom Fab WCF100344-CP 4" Intake Kit W/Air Box - Candy Purple at 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. 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.

Great
Size: One Size, Color: (015) Halo Gray / / Astro Pink
Product is as described, love the material and it’s true to size. The shape is very nice and the material is sun protective which is good to control sweating in your head.

Cute hat but a little big
Size: One Size, Color: (015) Halo Gray / / Astro Pink
Nice hat, fits a little big. lightweight and great fabric quality. I just need a hat that fits perfectly or I'm not comfortable. this one was a little big on the top.

good stretch
Size: 10 Long, Color: Dark Wash
Honestly, these are one of those surprisingly good basics—especially for the price.
The biggest standout is the stretch. They’re really comfortable and move with you, so they don’t have that stiff “jeans” feeling. They hug your body in a flattering way without feeling too tight or restrictive, which makes them easy to wear all day.
The mid-rise fit is also a sweet spot—not too low, not too high—so they’re super versatile with different tops.
What I liked:
Very stretchy and comfortable (almost feels like jeggings, but still looks like denim)
Flattering skinny fit through the legs
Easy everyday jeans—work, errands, going out
Great value for the price
What to know:
Material is on the thinner side (more comfort than “structured denim”)
They can lose shape slightly after a full day of wear
Not the most durable long-term compared to higher-end denim
Final thoughts:
These are perfect if you want cute, comfortable, affordable jeans you can throw on with anything. Not premium denim, but for everyday wear—they definitely get the job done and are worth having in your rotation.
