A true performance upgrade intercooler for the 991 Turbo / Turbo S. This is the most refined of all products we carry today, MERA launched in January 2022!- Colder inlet air temperature in the same conditions: 40°C/ 104 F (57°C/134,6 F), 17°C/ 30,6 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: 726 CFM (607 CFM), 19 % higher (do88 intercoolers + OE y-pipe vs OE intercooler + OE y-pipe)! See diagram below.
- 3D, freeform designed cast end tanks.
- Custom designed carbon fiber ambient air guides.
- Comes with high quality silicone hoses and accessories for installation.
MERA as in more, means more cooling, better airflow, more performance. Simply, MERA!
Starting off with a thorough market research in the beginning of our intercooler development for the 991, we understood that not many of the upgrade products on the market were really upgrades, but rather at the same level as the 991 standard units, or in some cases even subpar. We realized that we could not cut any corners to keep the cost down, we had to create the best possible solution for the given space in the car!
Upon launching this intercooler kit back in 2018, we chose to go with a UK made Tube&fin core, enabling great cooling and airflow paired with a low weight. It has proved very well over the years, featured on various 1000 HP builds. In the spring of 2022, it´s time for the next phase in the constant development of the do88 products. After thorough testing, we chose to move over to a Bar&Plate, motorsport-grade core from Garrett, thus bringing this already highly effective upgrade to the next level.
Overall differences:
- 13% higher airflow compared to the previous version.
- New, lighter airduct made from real prepreg carbon.
- 3,1 kg weight increase per intercooler compared to previous do88 intercoolers.
All in all, the weight increase compared to the OEM units is relatively small considering the sheer size of the intercoolers, and the fact that it´s an all-aluminum, dense construction. Our intercooler weight is 8,5 kg (18,74 lbs) per piece and the 991 OEM intercooler weighs 3,1 kg (6,83 lb) per piece. As much as it may seem in terms of weight increase, it is more than well compensated for if we consider the performance gain these intercoolers provide!
The intercooler kit comes with hoses adapted for OEM or do88 (63 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 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 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!

Great option for a natural finished look
Size: 1.8 Fl Oz (Pack of 1), Color: Original, Size: 1.8 Fl Oz (Pack of 1), Color: Original
I have been using Colorscience Total Protection Face Shield SPF 50 Original color for over 5 years. I love that the color blends with your skin so well and provides a natural looking finish.
It does not cover all of my dark spots or defects, but it makes my natural skin look better. The finish is soft and silky and the 50 helps protect my skin from additional sun damage. If you are looking for a more natural finish, this is a great choice.

Made my blush look orangey
Size: 1.8 Fl Oz (Pack of 1), Color: Original
I absolutely loved the feel and finish of this tinted sunscreen, but with or without my foundation on top of it, my Benefit Dandelion blush went from pink to a shade of orange. I have fair skin, blue eyes and strawberry blonde hair, which at this time of year is more strawberry than blonde. The orangey shade is definitely not my color. I was sad that this didn't work out, because the Colorscience made my skin look radiant really, until an hour or so after blush was applied. I so wanted a replacement for the Australian Gold Mineral sunscreen in original tint, because even though that tint looks great color-wise, it also makes my skin look dry and therefore accentuates my wrinkles, even when I mix it with Olay microsculpting cream moisturizer before I apply it. The Colorscience didn't accentuate the wrinkles. I feel certain this color issue is either a conflict with my Olay moisturizer, my own chemistry or the Benefit blush; maybe a combination of the three. If you have oily skin this sunscreen is moisturizing so it might not work for you. Otherwise, you may want to give this a try. Hate that I had to return it. No matter what, I've had a run-in with skin cancer, so I won't go without spf. I just have to keep looking ancient and dry with AG until I find one that works better for my coloring, skin type, and that plays well with my moisturizer and blush. I'm 62 yrs young, normal to dry combo skin. Hope this helps!

Brown skin friendly! No white cast! 🥳 Bye dark spots!
Size: 2.6 Fl Oz (Pack of 1), Size: 2.6 Fl Oz (Pack of 1)
Brown skin friendly! No white cast! 🥳
Colorescience comes through again! This is a fantastic sunscreen. It’s SPF 50 and it protects against blue light. So if you’re trying to get rid of hyperpigmentation, this will help you on your journey. I usually use tinted sunscreen for that reason but luckily, we have a non-tinted option with this! I use this primarily on my body because it doesn’t get stain clothing. But sometimes I use it on my face too, on its own or under a tinted formula. I like the light coverage for my face to even out my skin tone.
The texture is light and thin; reminds me of Tatcha silk screen but without the slight tint. This goes on white but somehow disappears into my skin. Also the price point is a better value, here. Even better when it’s on sale! I love Tatcha and use it regularly but I am happy to have this in my stash now. I had to get the big bottle when it was on sale. The formula is very elegant and leaves a natural finish. It spread and blends like a dream! It is so quick! You will NOT have to rub this in for 30 minutes to get it to blend. This physical sunscreen is a daily essential for me. It doesn’t burn my eyes or irritate my oily skin. It’s water resistant for 40 min, so it’s good for the summer heat.
But where are all the photos? Cause sometimes we need proof, right? Well, here is my contribution. I’m wearing this on my body (neck, chest, arms, legs, hands and feet).
* I reached out to Colorescience to ask about the effectiveness against UVA (aging) rays for this product. Other countries will usually mark this on a PA scale, the strongest protection being PA++++. But in the US, sunscreen isn’t required to specify how much; they are required to make sure it has at least the FDA “minimum” protection against UVA, and UVB (burning) rays and they have to label it “Broad Spectrum.” SPF is the protection level against UVB only. Colorescience has started to label some of their products with PA++++. Since this wasn’t labeled like that, I asked. They told me they recently completed testing and No-Show has earned the PA++++ rating. So they are in the process of updating the packaging. Colorescience knows what we want, even though the FDA is asleep at the wheel.
