The Audi air to water-cooled applications required an advanced configuration that further expands on their cooling system and addressed higher cooling capacity and water volume.
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. Our multiple-pass system provides a slower temperature rise and faster recovery.
- 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 23" x H 17" x D 2.4" not including side tubes.
- Proven to be one of the most efficient heat exchangers in the market yet best priced as well!

Please Note:
- Vehicles equipped with a factory dynamic steering cooler must relocate this loop cooler. We recommend purchasing the Compact Fluid Cooler to move this steering cooling system. The stock factory dynamic steering cooler is visible through the top of the grille.
- Vehicles other than the B8/B8.5 S4 may not be able to utilize the provided air diverter plates due to fitment.

Heat exchanger for my Audi works amazing so far, definitely have been seeing lower temps at the supercharger, just don't do what I did and mount it on the crash bar with it off or if you do make sure your crash bar is not upside down when mounting it lol, thankfully the crash bar can mount upside down just have to drill a hole for the ambient sensor to clip to, love the upgraded exchanger though 10/10, also love taking the top cover off and showing the Merc Racing logo
I’ve bought this for my C7.5 rs7 I’ve looked at different ones and this the biggest one I can find. It’s not about the price but about flow/size what matters for maximum performance. And it’s a good deal. All I had to use was clamps and just the heat exchanger. Yes can’t mount it to crash bar bc of AC condenser infront, but I just used metal ship ties to old mounting points. And it’s really tight won’t move. Super easy and install! My 750hp rs7 isn’t heat soaking anymore from 6+ pulls which is really good. Fan kicks on less almost never now!
I can tell it was a nice little upgrade, the only thing that upset me was the threading on the passenger side hole was all messed up. I had to drill the hole bigger and re thread it myself. I just hope it doesn’t end up leaking.
Fast delivery and good packing
It came a little warped with few bent fins but holds pressure and has all necessary hardware
