IE Cold Air Intake Audi S4 / S5 B8 3.0 TFSI

The IE Cold Air Intake system for the 3.0T engine utilizes a built-in velocity stack and ram-air design to dramatically improve airflow and stabilize induction temperatures. You’ll immediately feel an improvement in horsepower and torque throughout the entire RPM range while enjoying a unique and addicting supercharger whine that sounds as good as it performs. Upgrade your Audi with the most feature-packed intake available!

IE engineers use an extensive array of testing equipment to maximize and verify the performance of the intake design, including digital analysis, flow bench verification, and power testing on our in-house chassis dyno. The result is an authentic motorsport design that instantly adds horsepower, torque, and snappy throttle response. Typical peak gains from our CAI are roughly 15-25+ Horsepower & Torque on a tuned car.

Dyno chart data was collected on our in-house Dynapack hub dyno on a full bolt-on stage 2 B8 S4 3.0T engine. Testing was performed back-to-back in exacting conditions; the only change made to the vehicle between runs is the swap from a stock intake to the IE Cold Air Intake Kit.
