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, a ONE-Gallon water volume, and amazing results.
At the point of design 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.
- Purge air easier with included bleed port.
- 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.
- Proven to be one of the most efficient heat exchangers in the market yet best priced as well!

Was going for the black but the polished product looks good can’t wait for my mechanic to put it on. Awesome thank you . Switching to jackal tune next !!!
Should have done this a long time ago! Glad I held out for a newer version with higher capacity and bleed port!
Couldn't ask for a better product. The Merc Racing Heat Exchanger just works! Jackal Motorsports is top shelf when it comes to Customer support.
This heat exchanger is beautiful! Flawless design and easy to install. I highly, HIGHLY recommend! Jackal once again, pulls through with the best products and top notch customer service!
