RacingLine Upgraded Boost Pipe Kit is a five piece set that replaces the restrictive factory rubber and plastic charge pipes with a larger-diameter aluminium hard pipe and four reinforced silicone hoses, giving your turbocharged 2.5 five-cylinder a smoother, stronger and higher-flowing intake path from the turbo to the throttle body.
FITMENT NOTICE:
EA888 Gen4 - Audi TTRS 8S (2017 onwards)
Why upgrade the factory boost pipes? - The standard Audi charge pipes have a few built-in compromises. They use a smaller internal diameter, soft plastic and rubber construction, and feature a moulded “dent” to clear the wiring loom. Together, these create turbulence, restrict airflow and become a failure point under increased boost pressure. This RacingLine kit removes those restrictions entirely. The result is a cleaner, more consistent airflow path, better turbo response and the strength to handle the demands of a tuned 2.5TFSI without ballooning, splitting or popping off.
What to expect on the car - This is a supporting modification rather than a bolt-on power upgrade on its own. On a stock car you can expect improved throttle response, more consistent boost delivery and far better long-term reliability. On a tuned car (Stage 1, Stage 2 or beyond), it removes one of the most common failure points and helps the turbo deliver air more efficiently to the engine, which translates into a stronger, cleaner power curve. The complete system is pressure-tested well beyond the standard turbo’s output, so it stays composed under the higher temperatures and boost levels seen on remapped engines.
Features:
- 70mm aluminium boost pipe – larger than the 63mm OD factory plastic pipe, with the loom clearance dent removed for smooth laminar airflow.
- Four reinforced silicone hoses covering the intercooler inlet, intercooler outlet, turbo outlet and throttle body connections.
- Stepped internal joints – port-matched transitions between hose and pipe to reduce turbulence at every junction.
- Fluorosilicone inner liner – resists oil and fuel permeation for long-term durability under heat and pressure.
- Convoluted intercooler outlet hose with stainless steel band – allows for engine movement without collapsing under vacuum or boost.
- Mikalor stainless steel clamps included throughout to reduce the risk of boost leaks and hose slippage.
Installation Notes:
Fitting requires removal of the factory charge pipework and careful routing of the new pipes around the wiring loom. We recommend installation by a competent technician familiar with the 2.5TFSI platform to ensure all clamps are correctly seated and torqued.
