The ARM B58 Turbo Inlet significantly enhances turbo performance for the Gen 1 B58 engine by increasing the turbo inlet diameter by 25% compared to the factory unit. A standout feature of the ARM B58 Inlet is its 2.5” inside diameter at the turbo snout—substantially larger than the OEM's 2.0” diameter—resulting in a substantial improvement in airflow.

By eliminating the factory sound mufflers, the ARM Turbo Inlet reduces air turbulence and promotes a smoother, more consistent flow into the compressor turbine. This results in faster turbo spool, improved throttle response, and increased power and torque across the powerband.

Designed as a direct-fit upgrade, the ARM B58 Turbo Inlet includes all necessary hardware to maintain full compatibility with OEM fittings.

PREMIUM CONSTRUCTION

Engineered for both performance and reliability, the ARM B58 Turbo Inlet begins with a CNC-machined aluminum fitting that integrates seamlessly with the OEM O-ring and C-clip, ensuring a secure and leak-free connection at the turbo snout.

The inlet body is constructed from 6-layer reinforced high-temp silicone, built to withstand extreme engine bay temperatures and maintain structural integrity.

At the intake side, the inlet expands to a 3.75" inner diameter, and includes a precision adapter for use with either the OEM intake or the ARM B58 Intake system, which maintains a full 3.75" diameter to the air filter for optimal airflow.

Turkey tendon, vitamin E, low in fat, and high in protein. A great little midday snack 😊
Flavor Name: Braided Stick (Chicken)
My dog really liked these iPaw Turkey Tendon Braided Sticks. Every time I gave her one she went nuts and destroyed it in less than 5 mins. She's 80 pounds and for most medium-large dogs it will be the same, they won't last long at all. But I imagine for much smaller dogs they'd probably be a good 10-15 min chew. They have a very mild and almost non-existent smell, and they texture is quite hard and firm, so I would be hesitant to let a dog with missing teeth have one. They may be a bit difficult to chew. My dog hasn't had any upset stomach or diarrhea issues after eating these, which is always something I can keep an eye out for when feeding her something new. So far so good! They've got turkey tendon and vitamin E which are both super nutritional for dogs, and they're low in fat and high in protein which is another huge plus. Especially if your dog has weight issues. They're pretty small and they don't last long, but that's ok, as long as my girl loves them and enjoys them that's all that matters to me. They make for a great little midday snack, and for only $14 I would absolutely purchase them again.

Chihuahua and Border Collie Approved
Flavor Name: Braided Stick (Chicken)
We got the iPaw Turkey Tendon Braided Sticks for our two senior pooches, and it’s safe to say they are an absolute hit in our household. Both of our dogs seem to genuinely love the flavor and the "chew" of these. They stayed engaged with the treat until the very last bit was gone. While they are hard, they aren't rock-hard. I was easily able to cut them up with scissors for our Chihuahua, who is missing several teeth. He was able to gum them down without any issues, which is a win for a pup with dental challenges. The only reason I’m giving these 4 stars instead of 5 is the price. They are definitely on the expensive side for the amount you get. Since my dogs go through them so quickly, it’s hard to justify keeping these as a "constant" staple in the pantry, but they make for an excellent occasional high-value treat.

Dogs loved them, but gone very quickly
Flavor Name: Braided Stick (Chicken)
I picked up these turkey tendon braided sticks as a chew treat for my dogs, and they had zero hesitation. Both dogs were immediately interested and happily worked through them without any convincing. They seem very tasty and easy for dogs to chew, which makes them a nice occasional reward. They seem to be of healthy, quality ingredients, which is always a plus. Similar to some other natural chews I’ve tried, they just don’t last very long with bigger or enthusiastic chewers. What looks like it might be a longer distraction turns into a fairly quick snack in our house. Still, the dogs enjoyed them and tolerated them well, so they work fine as a treat, just not a long lasting chew for large dogs.

Expensive for What You Get
Flavor Name: Braided Stick (Chicken), Flavor Name: Braided Stick (Chicken)
My dogs love chews and I like to try different kinds. I thought they would be longer lasting since they are braided and turkey tendon. These come in a small bag with just a few chews. The chews aren't very big either. They are chewy but not so much that they take a while to eat. I gave one to my 36 lb labradoodle and he finished it in a couple minutes - so it isn't a long-lasting treat at all. At this price point, I would expect more treats or something that lasts a while. My dog loved these but I expect more bang for my buck.

Great braided dog snacks, good ingredients - cost a bit much for the number you get
Flavor Name: Braided Stick (Chicken)
I ordered these Chicken flavored Turkey Tendon Braided Sticks for my three medium sized dogs. I had hoped these would last a little while so gave them one each (there was only like 6 in the pack), but they gobbled them down before I even realized it. They really loved them. I would love to get them these as a special treat every now and again, but they're just too expensive no longer than they last. I know that they're quality treats, made with good ingredients and that really matters, still for no more than you're getting I feel they should cost about a third less. At this rate they're about $3 a piece, and I could get more of some other treat for that price. But if you don't care about the pricing and want only the best for you dogs, then this would be a perfect choice.
