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.

Great Divider, bad instructions
Color: Black, Size: 1 Large Panel
Happy with this as a room divider. Good price point and sturdy. I suggest skipping the directions and using common sense! The steps are made complicated when they are not ... and if you follow the directions you will have to go back and fix the skipped step of inserting the rods into the screen BEFORE securing the frame. Would buy again.

Great socks!
These are great low cut socks with padding in appropriate places. The shape keeps them from sliding down in my tennis shoes. I just wish more than three pair came in the pack.
