Frequently Bought Together
The Audi air to water-cooled turbo and supercharged applications required an advanced configuration that further expands on their cooling system and addressed higher cooling capacity and water volume than any other product.
We took this challenge seriously and with our help from Audi owners/friends, we now provide you a cooling solution that performs amazingly on your Stock, upgraded or higher boost tuned applications.
Our unique patented design uses the entire area of these large vehicles to provide you with excellent cooling capacity, higher water volume, and amazing results.
At the point of the invention and taking to market, no other heat exchangers in the market were designed this way. This design allows for water to stay on the cooling stage longer and dissipate heat longer than other normal single and dual-pass systems.
- High-density fin core for excellent heat dissipation.
- Purges all air as it runs.
- Bleed port included for assisting air removal during installation.
- Durable black satin/matte coating finish on end tanks for long-life durability and resistance to road debris, great finish, easy to clean, corrosion resistance, and long life.
- All Aluminum hand tig welded construction
- Side Mounting brackets and bolts for crash bar install – Included
- Self-tapping screws for mounting included
- 3/4″ Tubes
- Dimensions: W 24″ x H 18″ x D 2.4″ not including side tubes.

10/10 would recommend, this heat exchanger is probably one of the best out there. Shoutout to Jose, I’m proud to represent for MercRacing!
TED CREAMER (verified owner) –
I’m a Autobody technician and have seen many aftermarket radiators and this by far is one of the best I’ve seen. Most of them even when you spend a lot on them they use thin aluminum and are cheaply made. This thing is a Tank and the welding is flawless. I upgraded the pump and I’m upgrading the intercooler as soon as It comes in. Can’t wait thanks MercRacing
CPineda97 (verified owner) –
Recently installed this beast on my 3.0T 2013 S4. Seriously solid piece of equipment and a big improvement over stock. Great customer service from Jose when I ran into a few mounting hardware issues. 10/10 recommend for anyone looking to upgrade their cooling system.
