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. The 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 hood Ram Air duct and inner fender. 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.

Expectations exceeded (and illuminated!)
I am so stoked about this purchase. Our outdoor lighting situation was terrible- motion-activated lights that cut out after ten minutes and zero power outlets outside. This umbrella light exceeded every expectation. Three brightness modes, all bright enough to actually see what you’re doing — no more squinting while socializing, reading, or attempting to do “work” outside. Cordless, easy to install, and long lasting. If you consistently forget to turn them off when you're done, you'll get about a week and a half from the batteries on the lowest setting.

Okay
I like that it fits my umbrella well, hinges open for easy application and removal, and that it has enough light for us to see our food at night.
I do not like that half of the outer lights do not work part of the time until I take out the batteries and swap them around.
Fine enough for the price, not worth the hassle of returning.
