IE Turbo Inlet Pipe For Audi 2.5T EVO RS3 & TTRS engines

Sold out


Your 5 cylinder 2.5L Audi RS3 or TTRS engine is capable of incredible power gains exceeding far beyond 500HP on a stock turbo with basic bolt-ons and software tunes. As the power levels begin to rise, factory flow issues become immediately apparent and restrict horsepower such as the factory stock air box and turbo inlet elbow. Adding your IE Cast Turbo Inlet Pipe upgrade removes the factory inlet's flow restriction and allows your turbo to breathe freely and make more power!


During our 2.5T RS3 & TTRS product development, IE engineers paid serious attention to the factory inlet and charge piping systems during serious track, road, and dyno testing on higher output Stage 2 power levels. While perfectly fine for stock power numbers, the stock equipped turbo inlet pipe was immediately identified to be restricting flow and reducing power output on Stage 2 equipped Audi 2.5TFSI engines.


We know you are as power hungry as we are and that stock restrictive inlet pipe, well, it just won't do! Our engineers set out to completely re-design this pipe with performance first. 3D scans were taken of the engine bay and stock inlet pipe to identify the space available to work in. This allows us to maximize the flow characteristics of the design without running into any clearance issues or rubbing expensive factory hoses or lines. The factory inlet also incorporated an emissions breather tube into the design of the pipe that interrupted airflow to the turbo. By choosing to design our own cast pipe, our engineers were able to design a much larger performance version with unique shapes and bends that aided in airflow resulting in a massive 28.27% increase in flow over stock!


Installing an IE Turbo Inlet Pipe Upgrade onto your Stage 2 tuned 2017+ Turbo 5 cylinder engine will result in an immediate power and torque gain helping you get the absolute most out of your turbocharger making it that much more fun on the street or give you the competitive edge on the track.


Designing a performance part is worth nothing if it can't hold up to the job. The IE 2.5T EVO Turbo Inlet Pipe Upgrade is manufactured from incredibly high-quality aircraft grade aluminum castings and in-house CNC machined for exacting tolerances. Our mounting flange is designed to the OE style and will never leak or back off like modular ring-mount styles used on other designs. You can install it once, forget it, and get to the fun without worry. No modifications to the vehicle are required to install and everything lines up as-if installed from the factory while retaining all OE emissions systems. Your new turbo inlet pipe is a perfect fit to stock sized intakes or as a perfect match to accompany your IE Carbon Fiber Cold Air Intake Intake system for ultimate flow.


Installation is fairly straight-forward and can be completed typically within a couple of hours. Although the majority of the installation uses common hand tools, a Dremel with a cut-off attachment is required. Click here to view and download the complete install guide.
