Audi fitted the B9 A4 and A5 2.0T with restrictive, irregular plastic charge pipes. The Integrated Engineering High-Flow Charge Pipe Kit replaces them with smooth, mandrel-bent aluminium for cleaner airflow from the turbo to the throttle body, and a turbo that finally breathes and sounds the way it should.

Features

• Up to 13% more flow than stock: smooth mandrel bends replace the factory pipes' abrupt bends and poor transitions.
• More spool sound: deletes the resonator chamber Audi moulded into the factory pipes.
• Grip-Lock ends: CNC-machined pipe ends bite into the couplers and stay locked in place under serious boost. Heavy-duty silicone couplers and clamps included.
• Fixes common B9 boost leaks: replaces the plastic connections and O-rings that typically blow off or leak.
• Complete hot and cold side: covers the full path from turbo outlet to intercooler and intercooler to throttle body.
• Built to scale: fits the factory intercooler or the IE FDS intercooler, and supports tuning, higher boost and hybrid turbos.

Fitment

Audi B9 A4, A5 and A4 Allroad 2.0T (2017-2020). Retains the factory mounting points.

Installation

Moderate difficulty, around 2 hours with basic hand tools. It's a true bolt-on that runs safely on stock software; an ECU tune unlocks the full gains. Supplier part number: IETPCK7.
