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.

Very well built, will last you a very long time
Style: Trifold, Style: Trifold
This wallet is very sturdy, and barely has any wear on it after I've purchased it over a year ago. Most wallets will start to greatly scuff, wear, or degrade/break down just from being taken in and out of your pocket but this wallet has held up particularly wear with VERY MINIMAL light scuffing. Quality leather so I know I will have this wallet for a very long time! It has great card holding capacity as i currently have about 10 cards in it and it still has a pretty slim profile. The wallet itself is a very nice, natural looking wallet. The ease of pulling cards in and out definitely has made me a fan.

Rugged, Stylish, and Built to Last
Style: Bi-fold
I bought this Carhartt oil-tan leather wallet for my husband, and it’s exactly what I hoped for. The leather feels thick and high quality, with that classic rugged Carhartt look. The stitching is solid, and it’s clear this wallet will hold up for years of daily use. It has plenty of card slots and an ID window, but still stays slim enough to fit comfortably in a back pocket. The canvas lining is a nice touch, and the embossed Carhartt logo adds just the right amount of style. It even came packaged in a collectible tin, which made it perfect for gifting. Highly recommend to anyone who wants a durable, functional, and great-looking wallet!

Great wallet, no RFID BLOCK
Style: Front Pocket
Well made good looking wallet lots of space and the magnetic cash retention is really strong. The RFID block doesn’t work at all, I put a security access card in multiple places in the wallet and it can read it from 4 inches away like it’s not even in a wallet. Great product just don’t expect good security coverage. Front pocket so harder for a bad actor to scan without you noticing but risk still there.
