Nitrous Express Instaboost EFI Jet PackNX Jets are manufactured on CNC equipment, and are guaranteed to be within . 0005 of specified jet size. In recent testing, using the same jet size, NX jets out flowed the competition by 35%! That's right 35% more flow through the same orifice, how you ask? The NX jet was designed to be more than just a hole in a piece of brass; its contoured inlet and multi stepped outlet allow turbulence free flow with no restrictions. Warranty Installation

I received this several days ago for my pit husky mix she is an aggressive chewer and it is still holding up, it's not as big as I thought it would be but it is big enough to wear she will not choke on it or get it lodged in her mouth and she loves it she carries it around everywhere definitely a good buy for us and we'll be buying more

Best Bones for My big dogs

Right when I gave my dogs these Willie Bones they went to chewing and would not put them down! They are the type of dogs that tear up stuffed toys and balls easily. These are really tough though!

Great bone for all dogs!!

I loved this bone! See my use of past tense 😂 I am so sad I bought this for my very destructive yorkie/shitzhu mix and he loved it so much! He was so at peace with it. I am sad to say that after having it for about a week or two it disappeared. I never let my dog go outside with it and I have tore my house to PIECES in search of it. He really misses it, I think I miss it more for him I can only hope this company will be having more available in the near future. This is a great bone for all dogs in my opinion. I managed to get my friends to even buy one for their dogs and the of course are just as pleased. Well until we can purchase another I will leave a great review regardless. Thanks Willie Bones for saving me and my dog

Was skeptical but my pup loves it

My dog is a heavy chewer but normally likes stuffed animals and tasty chews. I’m always trying to find something to occupy him that doesn’t fall apart. I didn’t think he would like a rubber toy but I was wrong. What I like about this bone is that it’s actually a “pretty” toy and it has a big hole through the middle that you can put treats/peanut butter inside. The hole is also good because the toy has a little “give” which makes it easier for my dog to chew on it. And though I can see teeth marks all over the rubber, pup hasn’t managed to destroy it after a week. He even loves to play tug with it. It’s a good quality toy.
