034 Motorsport - Billet Diverter (Bypass) Valve Upgrade for Audi/Volkswagen 1.8T, 2.2T, 2.7T.

034Motorsport is proud to offer our Billet Aluminium Diverter Valve for various Audi, Porsche, and Volkswagen vehicles! This high-quality, performance engineered diverter valve is designed to replace the factory plastic diverter valve, which is a common source of boost leaks.

This means that the valve lasts much longer, and is capable of handling increased boost pressure.

The 034Motorsport Bypass Valve is fully serviceable and rebuildable.

Good for a laugh at least and a messy kitchen
Color: black
While design, quality, and ease of cleaning are great!! These are not for highly food motivated dogs and puppies. My senior dog (100lbs) took a couple licks, he immediately proceeded to pick it up as one unit and carry it to his bed where immediately tore it apart to get to the good stuff. ~ I will say that it is durable and did not fall apart as he carried it. My 7mo old puppy (60lbs) was intrigued and quickly impatient and was able to flip it over and while this only made a little pumpkiny mess, what he did next was hysterical! He picked it up on the edge and threw up in the air and the mess surprised even him but only for a moment. He promptly did it again and on the third time he was able to break the top loose from the bottom and quickly cleaned up the toy and the mess on my kitchen floor and cupboards. Fair warning for those with energetically food motivated labs!! These have since been donated to local shelter with the same warning.

Great for dogs
Color: blue
My dog is obsessed with this! I put plain yogurt thinned with homemade broth in it and he’s entertained for a good 15 minutes, as well as being fairly calm afterward.

Good for Chewers
Theme: Football, Size: Large
Dogs love it, they been chewing on it and it's like new. Also I put treats inside and they really like that. I have a small pit mix and a puppy shepherd husky mutt. They play tug of war with it and it's holding up really good.

Great inside toy
Theme: Football, Size: Large
Our Rottie loves these! I wanted something like the Jolly Ball but that is soft for inside the house. She's had a lot of fun with this, picking it up, tossing it, playing soccer, etc.

A BIG hit with my BIG dog!
Theme: Football, Size: Large
My Great Dane/Boxer mix LOVES this toy. She is over 100 lbs and very strong. She got a hold of my son's real football last year and after she made the initial holes and deflated it we just let her have it. She completely ripped it to shreds in about 7 months but had such a blast tossing it around and galloping around the yard with it, I knew I had to replace it with something of the same shape but hopefully more durable. This is it! She really adores this. We play catch and tug with it and it seems like it's going to last a really long time. The rubber is flexible but strong. I'll try to get a picture of her with it and load it. I highly recommend this toy. We ordered the Large size, by the way. :-) 2-6-2015 - Update: I am just now ordering a new one. For nearly 4 years, the old one has been kept outside in the rain, sun, snow, and ice. She still loves to grab it, shake it, throw it up in the air and play tug with whenever she's outside. The rubber is just now starting to crack so it's time for a new one.
