Unitronic Intercooler Upgrade Kit for 2.5TFSI EA855 EVO Engines
The Unitronic Intercooler Upgrade Kit is engineered to deliver superior cooling efficiency for Audi RS3 and TT RS models equipped with the 2.5TFSI EA855 EVO engine. Designed as a direct OEM replacement, this intercooler features an oversized 24" x 10.2" x 3.54" bar-and-plate core with cast aluminum end tanks, proprietary internal fin and louver design, and TIG-welded construction for maximum durability and performance.
With a 71% increase in volume over the OEM intercooler, the Unitronic design drastically reduces intake air temperatures, ensuring cooler, denser air for optimal combustion and sustained performance. Whether on the street, track, or drag strip, this intercooler provides unmatched resistance to heat-soak, maintaining power output under demanding conditions.
Available in either a stealth black finish or raw aluminum, this upgrade integrates seamlessly with the factory mounting points and requires no cutting, trimming, or modification to the bumper, radiator support, or surrounding components.
When paired with Unitronic Performance Software (Stage 1 through Stage 2), the Intercooler Upgrade Kit helps maximize power gains and reliability, making it an essential component for enthusiasts seeking consistent performance and efficiency.
