Integrated Engineering's Cold Air Intake for the Audi B8/B8.5 S4 and S5 3.0T pairs a built-in velocity stack with a ram-air design to dramatically improve airflow into the supercharger while stabilizing induction temperatures. The factory-style mounts keep the install clean and rattle-free, and the result is a noticeably sharper throttle response along with the addicting supercharger whine this engine is known for.IE's own testing on an in-house chassis dyno, using a full bolt-on Stage 2 B8 S4 3.0T, shows typical peak gains of roughly 15-25 plus horsepower and torque on a tuned car, IE-published; the figure is measured on tuned engines, not on stock software.Important Compatibility InformationThis intake fits the B8/B8.5 S4 and S5 supercharged 3.0T engine. It does not fit early model S5 B8 vehicles equipped with the 4.2L V8.Features High-flow velocity stack channels charge air into the engine with minimal turbulence Multi-ply silicone couplers with internal stops for a continuous, smooth intake tract Sturdy aluminum intake pipe resists collapsing under high boost Black powder coat finish on the heat shield, velocity stack, pipe, and brackets Factory-style mounts, no modification required Optional carbon fiber lid upgrade What's Included Integrated Engineering velocity stack, heat shield, and aluminum intake pipe assembly (x1) 5-inch performance air filter (x1) Multi-ply silicone couplers and hardware (x1 set) A high-gloss carbon fiber intake lid is available as an add-on at checkout, or separately as the Integrated Engineering Carbon Fiber Intake Lid.Installation NotesInstall takes 30 minutes or less with basic tools, IE-published, and does not require any permanent modification to the vehicle.Product Specifications SKU / MPN: IEINCG2A Fitment: Audi S4, 2009-2015 (B8/B8.5), and Audi S5 Coupe, 2009-2015 (B8/B8.5), 3.0T supercharged — does not fit early S5 B8 with the 4.2L V8 Frequently Asked QuestionsHow much power does this add?IE's in-house dyno testing shows typical peak gains of roughly 15-25 plus horsepower and torque on a tuned car; the figure applies to tuned engines, not stock software.Does this fit my S5?It fits the S5 Coupe with the 3.0T supercharged V6. It does not fit early model S5 B8 vehicles equipped with the 4.2L V8.Can I add the carbon fiber lid later if I skip it now?Yes, the carbon fiber lid is also sold separately and bolts onto this intake at any time.Do I need any hardware not included in the kit?No, all silicone couplers and mounting hardware needed for a factory-style install are included.
