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.

Nice office chair!
Color: Dark
This is a nice office chair. All of the features work as stated. I would say the seat is slightly more firm than I prefer, but comfort is subjective. The pleather is soft and I like that the arm rests fold out of the way.

This Marsail Executive Office Chair Is Excellent For A Comfortable And Polished Desk Setup
Color: Dark
This Marsail executive office chair is excellent, and it brings together comfort, support and a clean professional look in a very practical way. The PU leather has a smooth, polished presence that suits a desk chair well without looking overly bulky. I appreciate that the design includes flip-up armrests, a height-adjustable seat, swivel movement and rolling mobility in one complete chair. The cushioning gives the chair a substantial seated feel, while the back design adds support without making the chair look heavy. It is an office chair that feels thoughtfully built for daily desk work, focused tasks and general seated comfort. The chair arrived securely protected and in very good condition, with the main parts kept in place well through transit. The PU leather surfaces looked clean, smooth and free from distracting marks when unpacked. The base, wheels, armrests, backrest and hardware all appeared properly finished and ready for assembly. Nothing about the chair parts looked loose, flimsy or poorly handled when it arrived. The included components were organized. The appearance of this chair is one of its strongest qualities because it has a dark, sleek and professional style. The chair fabric gives it a refined executive look, while the breathable mesh center keeps the backrest from appearing too solid or oversized. The flip-up armrests blend into the design nicely and add a cleaner profile when raised. The chair has a balanced shape, with a supportive back, plush seat and wide base that all work together visually. It looks modern without being too flashy, which makes it easy to place with different desks and work areas. Functionality is where this chair becomes especially practical because it is easy to put together and simple to adjust. The height adjustment works well for getting the seat into a comfortable position at a desk. The swivel and rolling movement make it easy to shift, turn and reach without the chair feeling stiff. The reclining range and gentle rocking function add a useful option for leaning back during breaks. The flip-up armrests are especially convenient because they allow the chair to tuck under a desk more easily and create extra freedom of movement when needed. The value is strong because this chair offers several useful features in one well-rounded design. The thicker cushioning, contoured support, PU leather surface, breathable backrest, reclining function and flip-up armrests all add to its usefulness. The sturdy base and stated 300-pound support rating also give it a more dependable feel than a basic desk chair. It provides the comfort expected from an executive chair while still offering space-saving details that make it practical. For the features, comfort and overall build, it delivers a very complete office seating option. I highly recommend this Marsail executive office chair for anyone wanting a comfortable, polished and functional desk chair. It is excellent, easy to put together and built with enough adjustability to support different work habits. The combination of plush cushioning, ergonomic shaping, smooth movement and flip-up armrests makes it especially useful for a home office or workspace. I also like that it has a professional look without sacrificing everyday convenience. It is a strong choice for dependable seating that looks good, works well and offers solid comfort.
