Tax included. Shipping calculated at checkout.

DO88 Performance - The world´s first model adapted inlet hoses for Porsche 992 Turbo, Carrera, -S, -GTS!

To Fit:

  • Porsche 911 (992.2): 2019 onwards
    Model: Turbo / Carrera / Carrera 4 / Carrera S / Carrera 4S / Carrera GTS / Carrera 4 GTS


The inlet system on the Porsche 992 is completely revised from previous versions. It has a completely different layout but the principle is the same of course. As ever – as cold air and as much of it as possible is what brings effect and elevates the driving experience behind the wheel.

Key figures

  • More air to your engine, less back pressure and better airflow! Airflow at 0,175 bar / 2,54 psi pressure drop: 775 CFM (667 CFM), 16 % higher! See diagram.
  • 3D, freeform designed inlet hoses made from the finest silicone.
  • CNC-machined turbo inlet adapters.
  • Fits towards OE or do88 air filter box (66 mm).


The efficiency of a turbocharged engine is under direct influence of the inlet air temperature (IAT) and the back pressure in the system. A crucial aspect, yet very often overlooked, is having sufficient airflow before the compressor to avoid surge. Less vacuum and colder air enables the turbo to produce a larger mass which in the end means more air to the intake – summing up, this means noticeable power gains. There are great power wins to be earned with a good induction system! Throughout our years in this business, with countless hours of evaluation and development, we have seen the coherent connection in between IAT, sufficient airflow to the compressor, and the impact this has on the output. The Porsche 911, with its twin turbochargers and vast tuning potential, is always begging for more air!. That was always the case with the 911 – it still is!

DO88 turbo inlet hoses

We started the development by 3D-scanning the entire designated area on the car. This allowed us to work in a sensible manner, with the products in our CAD-environment using SolidWorks. The entire air filter system is optimised for airflow and radiuses and angles are reworked many times to achieve the best result! The finished product is verified with both Computer Flow Dynamics (CFD) as well with our Superflow SF1020 flowbench. All efforts are made to offer real and trustworthy data for you as a customer.

The kit comes with hoses in a textured black finish, CNC-machined adapters towards the turbos and top-quality, black hose clamps. The hoses are adapted to the OE air filter boxes, or the do88 air filter system with 66 mm connections.

Please note that these hoses provide a good upgrade. We consider them a solid first step in the refinement of your Porsche 911. However, we´d like to underline the fact that the best effect is achieved when these hoses are used in junction with the do88 air filter system. With that upgrade, all restrictions before the turbo inlet are eliminated and the turbos can reach their full potential!
