A true performance upgrade intercooler for your Porsche 911 (991.2) Carrera!

- Colder inlet air temperature in the same conditions: 24°C / 75,2 F (34°C / 93,2 F), 10°C / 18 F lower. See diagram. - More air to your engine, less backpressure and better airflow! Airflow at 0,075 bar / 1,09 psi pressure drop: 236 CFM (181 CFM), 30% higher! See diagram. - 3D, freeform designed cast end tanks with 2 3/4" (70mm) hose connections. - Custom designed carbon fiber ambient air guides. - Comes with high quality silicone hoses and accessories for installation.

This intercooler is part of our MERA selection . MERA, as in more, means more cooling, better airflow, more performance. Simply, MERA !

The intercoolers feature cast end tanks that distribute the airflow over the full core in a very precise way. This is very important as a good tank design will be beneficial for both pressure drop and cooling efficiency. To be able to fit an intercooler with appropriate thickness for the job, it was also necessary to design a new upper ambient air guide. This was designed in our 3D-scanned environment to ensure perfect fitment to the vehicle-integrated air guides, as well as the intercooler. To further remove bottlenecks, the intercooler kit MERA has intercooler connections that are 70 mm (2 3/4 inch) to really allow for the air to pass without restriction. This also means that there are new hoses included for each position, of which all are 3D-designed with maximum airflow in mind. All hoses are CFD-tested to ensure this. The hoses on the turbo outlet are made from a high-temp spec. material, rated to 240°C (464°F) continuous temperature. In order to really take advantage of all the heat-transferring ambient air, the carbon ducts come with proper seals towards the body, forcing all of the air to pass through the core, and not escape around it.

The intercooler kit comes with hoses adapted for OEM or do88 (54 mm) Y-pipe. What differs is the included hoses. Choose your version in the drop-list above.

When it comes down to performance, the do88 intercoolers significantly reduce the intake temperature! In the graph the difference towards the OEM 991 units is presented. The data is collected with an AIM race logger under 3 consecutive runs in an immediate sequence. Full throttle accelerations between 50-240 km/h (30-155 mph) in a Porsche 991.2 Carrera. No cooldown in between, just full pull.

The test was conducted in the following manner: Firstly, 3 runs were made with the car equipped with OEM intercoolers. Stop, fast change of parts to the do88 intercoolers. Shakedown for a few minutes and then 3 runs made in the exact same way as with the OEM parts. The decrease in inlet air temperature is significant, peak delta is 10°C (18 F) see the graph!

Cooling is important, and so is airflow. After many hours of development, refining the end tanks and choosing a core to meet our demand, the result is an intercooler that is much more efficient in terms of heat transfer as well as airflow. Using our in-house Superflow SF-1020 Probench, the airflow is verified as a complete system, with hoses on both inlet and outlet, for both the OEM 991 intercoolers, and the do88 performance intercoolers.

What you see is what you get – MERA performance from do88!
