Get the Wehrli Custom Fab WCF100344-CB 4" Intake Kit W/Air Box - Candy Blue from 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.

Dogs would not even put in their mouth!
Flavor Name: Beef, Size: Large
Toy is rock hard. Have seen toys like that before, but the smell is disgusting. I have 5 dogs, and while this was purchased for one in particular, none of the dogs would chew on it. Only one put it in his mouth, and then immediately spit it out. My dogs are not picky or finicky but none would have anything to do with it. Total waste of money.

8 months later, my dog's favorite toy by far!
Color: Ring, Color: Ring
My dog has a LOT of toys, and this is her favorite. We've had it for 8 months and it still holds up. She likes to pull at the stitching (and has removed a bunch), but the toy still holds together surprisingly well. It's a great value for the money.

Not good for aggressive chewers
Color: Ring, Color: Ring
My aggressive chewer had pieces of leather and felt chewed off within 10 minutes. Had to take it away from him because I didn’t want him swallowing them.

It's a do-not for me
Color: Ring
Bought for my doodle and the toy lasted less then two days. Not very durable. Inside the toy were layers of what looked like felt. Took it away from dog
