Grab the Wehrli Custom Fab WCF100191-BC 4" Intake Kit W/Air Box - Bronze Chrome from GAP for your GM Silverado/Sierra 6.6L Duramax today. 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. This design significantly increases airflow 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. 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.

This works!
I’ve got Rosacea and not only does this really calm down the redness it works well with my makeup. Doesn’t pill at all. Absorbs really well, no scent or at least I do not detect it. Does not irritate my skin.

The only option for reactive skin
I have EXTREMELY sensitive skin that breaks out in either a rash or acne with anything i try to put on it. This is the only lotion i can use. My sister is the same. Anytime i switch to something cheeper, i eventually come back to this!

FAKE! Caused burning stinging and pain. AVOID
Counterfeit product-avoid! Don’t buy it from here, get the actual product from Bioderma directly. I used this and it made my face sting, itch and turn a bright red. Then came the BURNING! After avoiding it for a week my face is finally healing. I didn’t notice the horrible packaging until it was too late—compare the photo of the product I got to the actual product from Bioderma and you’ll see the difference.
It is extremely unethical for a seller to send FAKE products that cause PAIN and redness all to make a dollar. Not cool.
