WCFab 2011-2016 GM LML 6.6L Duramax 4" Intake Kit with Air Box.

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.

Supersedes WCF100337. This intake is not compatible with discontinued models WCF100641, WCF100691, or WCF100716 unless you have a compatible aftermarket intake horn.

Air box is NOT compatible with intake pipe from kits WCF100337, WCF100689, or WCF100691.

Dogs love it
This our second one. The fogs destroyed the first one. Good toy and great for applying peanut butter in the grooves.

Great toy
Style: Turtle, Style: Turtle
I bought three of these turtle toys as Christmas gifts for various family member's dogs. Every single dog loves it! My dog has never been interested in any other treat toy I've given her. She's just not a foodie type dog. But, she's crazy about this one. She loves that it's floppy and the crinkly noise that it makes. The treats are surprisingly secure but she's happy to work at getting to them because the noise is rewarding during the process. While the edges of the treat pockets are starting to fray a bit, it doesn't affect the usability of the toy at all. I'm honestly shocked that my dog hasn't Shredded the entire toy with the amount of enthusiastic chewing she's given it. The only issue I have is that the opening to the shell is a bit small. It's kind of difficult to get the toy's long neck stuffed into the shell. But, I suppose if it was any bigger, it would be too easy for the dog to pull it out. So, overall, this dog toy is a huge winner!

Good for dogs who like to rip stuff up
Style: Alligator
Apparently it’s really good because my dogs already destroyed it. So I’ll take that as a success. It’s a good size for big dogs. Not the strongest, but I didn’t get it for that reason, I got it to be destroyed. Both my dogs were able to play tug of war with it.

A great enrichment toy to keep your dog occupied
Style: Fox
Do you have a small furry gremlin disguised as a dog in your life that needs entertaining while you work? Get yourself one of these! PROS - it keeps a smart dog occupied for anywhere between 10-20 minutes - if keeps a less than smart dog occupied a lot longer - you can fit quite a lot of treats of different sizes in there - you can throw it in the washing machine when it gets too dirty - also doubles as a tug of war toy CONS - it gets dirty fast - if you have a heavy chewer they'll rip it up and render it useless pretty quickly - it squeaks (good for dog not for human) This is one of my girls favourite toys, even now that she's a bit older and doesn't need constant stimulation she still enjoys running around with it and digging the treats out.

Dog loved it.
Style: Frog
Dog loved it, squeaker lasted about 5 minutes, which is about normal for any toy I’ve given her.
