More air to your engine, less back pressure and better airflow!

1. Airflow (59mm version) at 0,175 bar / 2,54 psi pressure drop: 1049 CFM (660 CFM), 59 % higher than OE! See diagram below.
2. 3D, freeform designed inlet hoses made from the finest silicone.
3. CNC-machined turbo inlet adapter.

Considerations:

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 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.

DO88 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 black finish, a CNC-machined adapter towards the turbo and top-quality, hose clamps.

Note, please select your correct size option required from the drop down menu:
1. 47mm if you have OE turbo.
2. 54mm if you have Hybrid turbo with Ø54mm compressor housing inlet.
3. 59mm if you have Hybrid turbo with Ø59mm compressor housing inlet.
