Show original supplier description

The CTS Turbo C7/C7.5 Audi 4.0T intercooler is engineered as a direct upgrade for C7/C7.5 Audi A8, S6, S7, S8, RS6, and RS7 models equipped with the 4.0T engine. This intercooler offers a significant improvement over the stock OEM core by providing enhanced durability, superior water flow, and faster intake air temperature (IAT) recovery. The design aims to reduce the risk of failure under high-performance conditions and ensure optimal engine operation. Key performance benefits include improved airflow with a higher CFM rating than the stock system, allowing for potentially higher power output. The intercooler's construction features additional fin density and added cooling columns, contributing to enhanced cooling efficiency. This results in lower intake air temperatures, which translates to more consistent and reliable performance, especially during spirited driving or high-performance pulls. This intercooler is designed for direct fitment on the following Audi models: C7 S6 4.0T, C7 S7 4.0T, D4 A8 4.0T, C7 RS6 4.0T, C7 RS7 4.0T, and D4 S8 4.0T. It is a replacement for OEM part number 079145785J. While the product offers improved flow using standard size hose connections, specific installation may require adjustments as detailed in the installation guide. Note that tuning may be required for optimal performance gains, with Stage 2 software tuning mentioned in relation to similar performance upgrades for these vehicles.
