The VW/Audi MQB platform is the perfect candidate for a sleeper street build or full-blown track monster. Whether it's a VW Mk7 Golf R, Audi 8V S3, or 8S TT 2.0TSi, the potential power of the TSI/TFSI engines is incredible.

Simple bolt-ons and a tune can net you over 100 horsepower and 120 lb-ft of torque, but with great power often comes great heat. All that power requires powerful cooling, especially considering the MQB platform vehicles use coolant to cool the engine, transmission fluid, and oil. Even with up to two auxiliary heat exchangers, these vehicles can still see reduced transmission performance and oil temps well above the safe limit after a few laps around the track.

Luckily, Mishimoto has a solution to keep your MQB VW or Audi cool and keep you on the track longer.

The Mishimoto 2015+ VW/Audi MQB Performance Auxiliary Heat Exchanger is the perfect upgrade for your stock auxiliary heat exchanger, DSG cooler, or both! Our auxiliary cooler increases core volume by 52% and coolant capacity by a massive 106% over stock. The core of the Mishimoto aux cooler also utilizes louvered fins to effectively circulate air throughout the core and boost fin surface area by 68%. The dual-pass design balances flow with cooling performance for maximum efficiency, while strutted tubes throughout the core ensure durability through the twists and turns of the road or track. The included stainless-steel stone guard adds even more durability to this 2015+ MQB auxiliary heat exchanger by protecting it against road debris kicked up by the car you're about to overtake.

Like all our VW/Audi performance products, this 2015+ VW/Audi MQB Performance Auxiliary Heat Exchanger is backed by our Mishimoto Lifetime Warranty for a lifetime of performance.

                Durable, Fun, Useful!
                Size: 1.8in for Puppy Dogs
                This treat dispenser is so great! For one thing, it's sturdy and will last forever. It will get lost before it wears out. This is my second order because I can't find the first one . . . so I bought this pack of two. In one, I put peanut butter. In the second one, I put toothpaste, just a squirt for each opening. My dog LOVES to chew on this even after she has consumed 98% of whatever I put in there. In short, it occupies her attention, which is a blessing! It's both a treat and a toy. It also bounces well and can be thrown as a ball. It will LAST far longer than any ofher other balls, too. My dog has a tiny mouth and larger balls are too big or too hard for her. If I could give it more stars, I would!

                DURABLE
                Size: 2.8in for Small & Medium Dogs
                My dog loves these balls almost as much as she loves tennis balls, which she tears up within a day. These two balls have lasted over a week with no signs of wear. I was unsure when I ordered them but they do bounce, not quite like a tennis ball but enough to keep my dog's attention. When using toothpaste in these balls I had to put it deep into the openings or she just licks it off of the surface and when its that deep, it doesn't squeeze out like I think it should. It just stays in the crevasses and gets old and hard. As a ball it's great, as a toothpaste delivery system it's not so great.

                Perfect For Sophia!
                Size: 1.8in for Puppy Dogs, Size: 1.8in for Puppy Dogs
                These little balls are the perfect size for Sophia who is a 7 lb Yorkie with a teeny tiny mouth. The slots in the balls make them very easy for her little teeth to grab hold of and carry. The quality of the rubber is excellent, strong and durable. They're holding up great so far! She loves them and so does her Mama! 5 stars!

                Horrible, don't buy
                Size: 1.8in for Puppy Dogs
                I wanted to love these. They had so much potential. It's a good size. It seems like a good shape. But ... 1) first red flag should have been the packaging. It looked like it was a dollar store item that had beenblost on the shelves for years. 2) the rubber is super flexible. I was expecting it to be sturdier. I can flatten the ball without lich force. Maybe that doesn't matter. Naybe flexible is good. But I never got a chance to test out it's durability against a pup because... 3) it smelled. I expected it to smell like rubber, like most rubber toys. Rubber smell is okay. Usually rubber smell goes away. But, this was NOT a rubber smell. It smells like peppermint or something similar. It's like someone sprayed essential oils when mixing the rubber and now the smell will not leave. I soaked it in dawn soap half the day and overnight. I rubbed. I scrubbed. The smell actually gets worst the more you scrub it!!! It's like a scented marker or scented eraser, but you do NOT want the scent in a dog toy! My dog cannot smell the food in it because the smell of the weird mint-like scent is so overpowering. He saw it had food, and wanted it, but every time he started sniffing wildly, he would recoil. Whoever thought it was a good idea to scent this was WRONG. Mint in the form of an essential oil is extremely poisonous to dogs!! So, why they would put a mint-loke scent ijto the dog's rubber treat toy is beyond me. I would return this if I hadn't throw out the package immediately. I considered pulling the package out of the trash once i realized the scent issue but other trash had already been dumped into the trash can over it and i didn't want to dig through trash. The ball is still soaking in soap. I scrubbed again this morning. I let obe dry out. No luck. It actually seems to get worst the more you scrub, like it really is embedded in the rubber itself. Yuck!!!
