Intake Manifolds for Audi A6 (2012-2015) 3.0L Left & Right

Direct-Replacement Lower Intake Manifold Set for 2012-2015 Audi A6 (C7)

What it Does: The lower intake manifold set replaces the failure-prone factory runner flap assemblies on the 2012-2015 Audi A6 to resolve intake runner DTCs and eliminate unmetered vacuum leaks beneath the supercharger.

The Stock Audi A6 Intake Runner Flap Failure

Positioned directly beneath the Eaton TVS supercharger on the EA837 3.0 TFSI V6, the factory lower intake manifolds endure intense thermal cycling and crankcase blow-by. Over time, heat degrades the internal composite runner flap pivot points and mechanical vacuum actuators. This deterioration leads to excessive shaft play, carbon-induced flap binding, and failure codes such as P2006 and P2007 (intake runner flaps stuck closed). Additionally, warping of the factory housing degrades the port seal interfaces, creating unmetered air leaks that trigger rough idling, lean fuel trims, and persistent misfires.

The Engineering Solution

This left and right manifold pair delivers a reinforced structural replacement manufactured from premium cast aluminum and high-temperature composite polymers. Engineered to match OE flow dynamics, both units feature precision-seated internal tumble flaps that resist binding under high intake manifold vacuum. Integrated flap actuators restore smooth bank-to-bank charge motion, while pre-installed fresh port seals guarantee an airtight seal against the cylinder head intake ports. The direct-fit design installs beneath the supercharger without modification, resolving 06E133109 and 06E133110 failure points permanently.

Frequently Asked Questions & Fitment Warnings

Does this fit the C7 A6?

Yes, this is a direct fit for the 2012-2015 Audi A6 equipped with the EA837 3.0L supercharged V6. Not compatible with 3.0L TDI diesel, 2.0T inline-4, or 4.0T V8 engines.

What service procedures are required during installation?

The supercharger assembly must be removed for installation; technicians should replace supercharger gaskets and reset ECU runner flap adaptations using diagnostic software post-assembly.

The Audi Precision Standard

Manufactured to rigid European tolerances, these manifolds restore precise air-fuel velocity and intake charge motion, ensuring OE drivability and eliminating check engine lights without ECM recalibration.
