Description

CSF Thermal Black High-Performance Intercooler System for C8 Audi RS6 / RS7 [8194B]

Following the debut of its world-exclusive all-aluminum radiator for the B8 S4 / S5, CSF proudly announces another groundbreaking release: the highly anticipated High-Performance Intercooler System for the C8 RS6 and RS7. In collaboration with Southern California’s leading VAG specialists, Pacific German, CSF has developed this essential intercooler system to unlock the full performance potential and elevate the power goals of the C8 platform. Once again, CSF has partnered with strategic manufacturing expert PWR to deliver Formula 1-level performance to the aftermarket.

Design and Engineering

The standout feature of the CSF by PWR RS6 / RS7 Intercooler System is its Formula-1 grade intercooler core. Through CSF’s strategic partnership with PWR, this advanced core has been integrated, setting it apart from anything available in the performance aftermarket. Featuring 3mm tall rolled tubes with turbulated inner fins, the design optimizes heat dissipation from the charge air on the pressure side of the intercooler core. Complementing this is the 4.85mm tall multi-louvered fin, recognized as the most efficient in the high-performance industry and delivering performance on par with PWR’s Formula-1 grade race intercooler cores. This proven technology, also utilized in CSF’s air-to-air twin intercooler systems for the Porsche 992 Turbo/S and GT2RS, effectively eliminates heat soak and reduces intake air temperatures (IATs). It enables vehicles to maintain peak performance during prolonged and demanding driving conditions. Dyno testing highlights a significant advantage of CSF’s C8 RS6 / RS7 Intercooler System: its rapid recovery speed in dissipating heat from the turbocharger system. In comparison, the OEM intercoolers on the C8 platform are prone to heat soak, leading to uncontrolled IAT increases. This triggers the ECU to pull engine timing, resulting in reduced performance.

CNC Machined Billet End Tanks

Like other products developed through CSF’s partnership with PWR, the new RS6 / RS7 Intercoolers feature 100% TIG-welded, machined billet aluminum end tanks, replacing the OEM crimped cast aluminum versions. This upgrade not only enhances aesthetics but also significantly improves strength, ensuring longevity and durability for high-performance applications. The CNC-machined billet end tanks are engineered to handle increased boost pressures from bolt-on modifications, high-performance tuning, and upgraded turbochargers. With the growing enthusiasm among RS6 / RS7 owners, the platform is already exceeding 800 WHP and moving toward four-digit power levels. CSF’s intercoolers are a critical component in achieving these ambitious performance goals.

Dyno Testing

CSF performed testing of its intercooler upgrade on a tuned Audi RS6 at VF Engineering using their in-house Mustang four-wheel dyno. The process began with a tuned RS6, completing multiple back-to-back dyno pulls with 50-second cooldown intervals (1-minute cycles, including 10-second pulls). The vehicle was then returned to its OEM tune, and the same testing sequence was repeated to establish baseline data for the stock intercoolers. Once the data was collected, the OEM intercoolers were replaced with CSF’s upgraded units, and testing resumed immediately, adhering to identical procedures with both the OEM tune and VF Engineering’s Stage-2 performance tune. Testing with the CSF intercoolers took place in the afternoon in a dyno cell 8°F warmer than the morning tests conducted with the OEM intercoolers. Despite the higher ambient temperature, the CSF intercoolers delivered substantial improvements. The OEM intercoolers exhibited an average temperature rise of 20°F per pull, while the CSF units achieved a 4°F average temperature drop per pull. At peak performance, the CSF intercoolers ran up to 30°F cooler than the OEM units. The OEM intercoolers began to show heat soak by the third pull, whereas the CSF intercoolers demonstrated nearly instant recovery and showed minimal signs of heat soak, even after the fifth pull.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
