The complete charge air cooling solution for Porsche 911 (991.1) Turbo / S!

This kit comes in at a package price and includes our motorsport grade intercooler and high flow y-pipe with all hoses and accessories for installation. To even further enable a better breathing engine.

The intercooler kit MERA and the y-pipe are great products on their own. Used together they generate a great inlet temperature reduction, less backpressure throughout the whole system and thereby allowing more power.


Key figures:

  • Colder inlet air temperature in the same conditions: 37°C/98,6 F (55°C/131 F), 18°C/32,4 F lower. See diagram below.
  • More air to your engine, less backpressure and better airflow! Airflow at 0,175 bar / 2,54 psi pressure drop: 835 CFM (607 CFM), 37% higher! See diagram below.
  • Top-quality, high-density motorsport-grade, Bar&Plate cores from Garrett.
  • 3D freeform designed cast end tanks.
  • Custom designed carbon fiber ambient air guides.
  • Y-pipe made of 2,5" (63mm) mandrel bent aluminum pipes.
  • Y-pipe made from a cast, smooth flowing collector part.
  • Y-pipe has two methanol injection connections (1/8 -27 NPT). The pipe is delivered with blanking plugs in these connections.
  • Comes with high quality silicone hoses and accessories for installation.


When it comes down to performance, the do88 bigpack significantly reduce the intake temperature! In the graph below the difference towards the OEM 991 units is presented. The data is collected with an AIM race logger under 5 consecutive runs in an immediate sequence. Full throttle accelerations between 50-250 km/h (30-155 mph) in a Stage 1 tuned Porsche 991. No cooldown in between, just full pull. During every test, the car was driven in Sport Plus, AC off.
The test was conducted in the following manner:
Firstly, 5 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 5 runs made in the exact same way as with the OEM parts. The decrease in inlet air temperature is significant, peak delta is 17°C (30,6 F) see the graph below!

Cooling is important, and so is airflow. After many hours in the 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 both intercoolers, hoses and y-pipe for both the do88 bigpack and the OEM 991 units. What you see is what you get – true performance!
