WCFab 4" Intake Kit with Air Box for 2004.5-2005 LLY 6.6L Duramax equipped Chevrolet Silverado or GMC Sierra 2500 / 3500 HD truck.

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 new design significantly increases air flow to your turbo producing improved horsepower and torque, quicker throttle response, and cooler intake temperatures by drawing cold air through the inner fender. 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.

Removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with included hydrophobic pre-filter cover, to help keep your MAF sensor, turbo, and engine airways contaminant free.

Full assembly finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck.

Highly recommended for all skin types!
Size: 3 Fl Oz (Pack of 1)
Game-Changer Night Moisturizer – Lightweight, Hydrating & Perfect for Sensitive Skin I’ve been using the CeraVe PM Facial Moisturizing Lotion for a few weeks now, and honestly, it has become a staple in my skincare routine. First thing I noticed is how lightweight and fast-absorbing it is. It sinks into the skin within seconds without leaving any greasy or sticky feeling, which is perfect if you don’t like heavy night creams. Despite being lightweight, it provides deep hydration throughout the night—I wake up with soft, smooth, and refreshed skin. What really makes this product stand out is its ingredient combination: • Hyaluronic acid keeps my skin hydrated by locking in moisture • Niacinamide helps calm my skin and reduces redness • Ceramides (1, 3, 6-II) strengthen the skin barrier I also love that it’s fragrance-free, oil-free, and non-comedogenic, so it doesn’t clog pores or irritate my skin. I have slightly sensitive and acne-prone skin, and this has worked perfectly without causing breakouts.

I’ve been using the CeraVe PM Facial Moisturizing Lotion as part of my nighttime routine and it has worked really well for my combination skin. The texture is lightweight, smooth, and absorbs quickly without leaving any greasy or heavy feeling. What I love most is how hydrating yet gentle it is. My skin feels soft, balanced, and calm by the morning. It layers nicely with my other skincare products and hasn’t caused any breakouts or irritation. The formula feels simple and reliable, which is exactly what I look for in a daily moisturizer. Overall, a great affordable staple for maintaining healthy, hydrated skin.

This Is That ‘Boring’ Skincare That Quietly Works So Well
Size: 3 Fl Oz (Pack of 1)
I’ve tried a lot of moisturizers over the years, and this falls into what people call “boring skincare” — and honestly, that’s exactly why it works so well. If you have acne-prone skin and deal with redness or irritation, this is one of those rare products that checks both boxes without overcomplicating things. The consistency is lightweight but still hydrating. It spreads easily and absorbs quickly into the skin without leaving any greasy or heavy residue. It gives my skin the hydration it needs without clogging pores or triggering breakouts. I’ve had no issues with acne while using this, which is not something I can say for most moisturizers. It also has Very minimal to no fragrance, which I prefer — especially great for sensitive or reactive skin. Overall: This isn’t a “flashy” product, but it’s consistent, gentle, and effective. It’s the kind of moisturizer you can rely on daily without worrying about irritation or breakouts.

-Daughter of Amazon Account-
Size: 3 Fl Oz (Pack of 1)
In the past I have used high end skincare products and wasted money. This is absolutely one of the best PM OIL-FREE facial moisturizers. This has helped my skin improve significantly over the last few months. Its super super light weight and pea size dots cover my entire face. I add a pea size to my cheeks, forehead and chin. It all soaks into my pores evenly without clogging them. Due to me using a serum by CeraVe as well. (Very important part of my personal skin-care routine) I have extremely sensitive skin and nearly break out with everything I use. However this helps being fragrance-free & OIL-FREE! Over the years I always thought high end brands were better than the lower cost friendly ones. (NOT THE CASE! At least for me.) I highly recommend this product for someone who is starting out using facial products or someone who has indulged in high end. This does WORK! And it leaves my skin feeling fresh and lightweight. I started seeing differences in my skin texture (for the good) within about a month after using it daily. I then backed off from it and use it every other day. Since I now have my skin where I need it to be.
