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.

                BEST sunscreen! No greasy/sticky residue!
                Size: 6 Fl Oz (Pack of 2), Style: Lotion
                I HATE putting on sunscreen! They’re always greasy yet somehow leave your skin feeling sticky at the same time (especially the spray on kinds)?! Most of them have a super strong smell, and even if it’s a good smell it’s so strong it ends up giving me a headache. A couple years ago Coppertone came out with a whipped sunscreen that I was borderline obsessed with! It changed my life when it came to the dread of putting on sunscreen. It was moisturizing, but not greasy. It left not a hint of stickiness, and it didn’t not have an overwhelming smell! I was ecstatic! I had it set to auto deliver the double pack all summer long! My whole family and extended family also loved it! Well, the very next summer they discontinued it and my family and I (especially) we’re devastated! They didn’t even come out with something similar. It was just gone! Since then I’ve been searching for any kind of comparable sunscreen to no avail! I’ve tried them all! Then, about a month ago I found this one!! This is it!! It’s only as good as the coppertone whipped, but in some ways it’s better!! It’s not greasy or sticky at all. It spreads easily and has the softest, lightest, most amazing smell as well! It feels like I’m putting on my favorite lotion! Plus, no one in my family has gotten the slightest bit burned! Even my beautiful porcelain skinned 4 year old daughter who you have to drag off the beach or out of the pool when the sun goes down because she thinks she’s a mermaid! 🤣 I have nothing bad to say about this sunscreen!! I have stocked up just in case…. But Please please please don’t discontinue it!! 🙏🏻🙏🏻

                Better than Shiseido for a fraction of the price
                Size: 6 Fl Oz (Pack of 2), Style: Lotion
                I bought this sunscreen for a trip to Florida but now it's my everyday sunscreen. My job includes driving around to body shops so my hands get a lot of sun, and I'm too embarrassed to wear driving gloves. I was using Shiseido's clear sunscreen stick (also SPF 50+) but had a slightly noticeable tan line at my wrist, both from my jacket and my watch so I wasn't sure if it was really working, despite the good reviews (and $$). This Banana Boat sunscreen feels so good that I decided to try it out for my hands every day, and it's fantastic. Smells good, not greasy at all it soaks right in, and the best part is my tan line is GONE. 10/10 please don't ever discontinue or change the formula.

                The best sunblock I've found!
                Size: 6 Fl Oz (Pack of 2), Style: Lotion
                I absolutely love this sunblock. I have sensory issues with any type of lotion and sunblock, but this stuff is incredible. It really is so lightweight that once it fully soaks in (which only take a few minutes) it feels as if there's nothing on my skin. This is huge for me, cause I just can't handle the feeling of any other sunblocks I've tried, even some more expensive brands. On top of all that, it definitely protects my skin from the sun, doesn't leave a white cast, and doesn't feel greasy while applying it.

                My favorite sunscreen for being active outside
                Size: 6 Fl Oz (Pack of 2), Style: Lotion
                I bought this last summer and now it's my go-to. I love it. It absorbs quickly, is very easy to just smear on, and has a nice, very light scent. I wear it when I go running and I sweat like a maniac so that tells you something.

                Possibly the best sunscreen on the US market
                Size: 6 Fl Oz (Pack of 2), Style: Lotion
                I'm a self-confessed sunscreen snob. I love trying new formulas, and I came to the conclusion years ago that US formulas aren't usually for me. We haven't had a new filter approved by the FDA since the last millennium, and our products reflect that. I can't tell you how many times I spent $40+ on 1.7oz of sunscreen that I ended up hating before I switched to mostly Korean sunscreens; and most of the US sunscreens I like can be described as "good...for a US formula." In short, I didn't have high hopes for this, and I was very pleasantly surprised. This is a very, very good sunscreen even among non-US formulas. It's lightweight, doesn't make my oily skin shiny, and dries down entirely so it doesn't feel tacky or slimy. I can layer over and over throughout the day without pilling or streaks. It also comes in a huge tube for a very low price. The only possible downside is that it's fragranced, which isn't a deal breaker for me. I wish they still sold the 3oz facial version because it's travel-friendly, but from what I can tell, it's the same formula. Try this, especially if you hate thick, heavy, shiny sunscreens. Unless you can't do fragrance, I think you will be very happy with it.
