Intake Manifolds for Audi S4 S5 (2010-2016) 3.0L Left & Right

Direct-Replacement Lower Intake Manifold Set for 2010-2016 Audi S4,S5 (B8 / B8.5)

What it Does: The lower intake manifold set replaces failing runner flap assemblies and leaking intake port seals on the 2010-2016 Audi S4 and S5 to restore proper air-fuel charge motion and eliminate check engine lights.

The Stock Audi S4,S5 Runner Flap and Flange Failure

Factory lower intake manifolds on the B8 and B8.5 platforms are subjected to extreme heat soak directly beneath the Roots-style supercharger. Over continuous thermal cycles, the composite runner flap pivot points bind, vacuum actuators deteriorate, and mating surfaces warp. This wear leads to unmetered vacuum leaks and mechanical runner flap binding, triggering diagnostic trouble codes such as P2004, P2005, or P2015 alongside uneven idle and rough low-RPM throttle response.

The Engineering Solution

This replacement lower manifold pair features reinforced aluminum housings paired with OE-specification composite runner flaps designed to resist heat distortion and mechanical wear. Each unit comes fitted with integrated runner flap actuators and new port seals to restore positive cylinder-to-head sealing against boost pressure in the EA837 3.0 TFSI engine. Restoring precise runner flap articulation ensures optimal intake charge tumble, clean part-throttle velocity, and zero unmetered air intrusion.

What's Included

• 1 Left Lower Intake Manifold (with integrated runner flap actuator and port seals)
• 1 Right Lower Intake Manifold (with integrated runner flap actuator and port seals)

Frequently Asked Questions & Fitment Warnings

Does this fit the B8 / B8.5 S4,S5?

Yes, this is a direct fit for the 2010-2016 Audi S4 and S5 equipped with the EA837 3.0 TFSI supercharged engine. Not for the 3.0L TDI diesel, 2.0T, or 4.0T engines.

Do I need to clear adaptation values after replacing the manifolds?

Yes, supercharger removal is required for installation, and you must clear ECU adaptation values and perform runner flap relearn procedures to reset position sensor baseline readings.

The Audi Precision Standard

European forced-induction platforms demand micron-accurate air charge metering to avoid check engine lights; these manifolds match factory mechanical tolerances to maintain seamless ECU integration and factory power delivery.
