Product Description

The AWE Performance Intercooler Kit is the definitive cooling solution for the legendary Audi 2.7T engine found in the B5 S4 and C5 A6/Allroad. At high boost levels - common with modern ECU tuning or K04 turbo upgrades - the factory intercoolers quickly become a bottleneck, leading to heat soak and significant power loss. AWE's engineering team designed this kit to provide a massive 37% increase in surface area, utilizing a high-efficiency bar-and-plate core that handles double the factory boost pressure with ease.

Unlike the European RS4 intercooler retrofits that require extensive cutting of the vehicle's chassis and bumper, the AWE kit is engineered specifically for US-spec frames. The included carbon fiber shrouds are not just for aesthetics; they are CAD-designed air ducts that ensure 100% of the incoming ambient air is forced through the core rather than escaping around the sides. This leads to intake temperature drops of up to 55°F and double-digit gains in horsepower and torque, ensuring your 2.7T stays powerful even during back-to-back pulls or in high ambient temperatures.
