Flashark Cold Air Intake for Audi B8/B8.5 S4 S5 Q5 SQ5 3.0T V6

The factory airbox on Audi’s supercharged 3.0T V6 (EA837) is heavily baffled to silence the engine, creating massive restriction. This stock corrugated plastic hose collapses under high boost, choking the supercharger right when you need power most.

The Flashark Cold Air Intake Kit opens up the intake path. Replacing the stock inlet hose with a smooth-bore, high-flow, mandrel-bent aluminum tube and adding an open steel heat shield forces a massive volume of dense ambient air directly into the supercharger.

This kit dramatically reduces intake air temperatures, delivers sharper throttle response, and sharpens acceleration. Best of all, it unleashes the legendary, addictive supercharger whine that the factory airbox hides. It integrates perfectly with the stock MAF sensor and factory ECU setup—no check engine lights, no rough idle, and no tune required.

Installation: 45–60 minutes, basic hand tools, 100% direct bolt-on.

Key Features

• Smooth-Bore Intake Tube — Mandrel-bent aluminum piping eliminates the restrictive factory accordion hose, preventing collapse under heavy boost and optimizing airflow.

• High-Flow Conical Dry Filter — Washable and reusable oil-free filter media provides massive surface area for clean, maximum airflow without risking MAF sensor fouling.

• Airstream Heat Shield — Heavy-duty black powder-coated steel shield blocks hot engine-bay air, using the factory cold-air ducting to maintain low intake temps.

• Unleashed Supercharger Whine — Removes factory sound resonators to bring out the aggressive, crisp supercharger whine under acceleration while keeping highway cruising quiet.

• Factory ECU Compatible — Precision-engineered to work flawlessly with stock air-fuel ratios; guarantees zero check engine lights (CEL) without needing a custom tune.

• Direct Bolt-On Design — Attaches to all factory mounting points; no drilling, cutting, or permanent modifications required.
