The S55 turbo engine that powers the BMW M2C / M3 / M4 F8X uses a Top mounted water-cooled intercooler instead of an “regular” air-cooled intercooler. This OE intercooler has a tube and fin core with clamped plastic end tanks. This construction has its drawbacks since it is prone to crack and start leaking coolant into engine or leaking boost pressure out of the tank sealings.

Our mission when starting this development of a new performance intercooler was to eliminate the OE intercoolers weaknesses and of course offer a great performance increase. During all test we have carried out during the development of our entire BMW F8X M2C/M3/M4 product range we see clearly how the peak power is directly equated with the IAT (Intake Air Temperature).
To get an exact 3D-model of the available space to design our intercooler in we did a detailed 3D-scan of our M3 Competition engine bay. In our Solidworks CAD-software we tried out several design concepts for our charge air cooler using the 3D-scan generated model.

The final design concept was decided after several CFD simulations in our Solidworks Flow Simulation software. In this software we can simulate air flow and measure pressure drop and air distribution over the core. We decided not to include internal air guides since several of our simulations showed they did more harm than good. The air flow is distributed perfectly over the core with our tank design without internal air guides as many claims is good. But in many cases, these causes turbulence and disruptions in the airflow.

Our final design resulted in a bar-and-plate core with TIG-welded aluminium casting end tanks. This offers a peace of mind for any High boost tune. We have managed to utilize a massive core 85% lager than OEM and decrease (16% lower) the charge air pressure drop and maintain drop-in installation without modifications. Decreasing the charge pressure drop over the intercooler has several benefits such as the turbos needs to work less to achieve target boost / lower temperature / improves throttle response. We have the equipment to calculate the pressure drop in our CFD calculation software and also real-world tests in our Superflow SF-1020 flow bench. On the water coolant side, we changed to a dual pass flow structure which allows the coolant to flow across the core two times before exiting the intercooler instead of the OE single pass structure.

We use a high density offset cooling fin on both the air and water side. Several tests were performed to find optimum balance in-between the air and water fins to get the maximum heat transfer. This gives our intercooler a huge increase in active cooling area compared to OE.

Naturally, this being a do88 performance product, we have executed thorough, severe, and continuous tests developing this product to ensure best performance. Not one compromise has been made.

All this hard work result in a product that in one way or another really will enhance the performance of your vehicle no matter if it is a standard car or a heavily modified monster! On track, on street, on strip, this charge air cooler will be your true companion!

I like the tray a lot. Quality is very good. Color (Brown) is attractive. Size is perfect for my nightstand. It holds phone, remote, eyeglasses, & phone. I threaded my phone charging cord through a corner of the tray. But it slides too easily off of the nightstand. I'm going to try to find something to stop it from sliding that will stick to the underside of the tray without harming the wood surface on my cherry nightstand.

Better than other flimsy trays
Color: Black, Size: Rectangle, Color: Black, Size: Rectangle
I got this to replace another flimsy valet tray I got as a gift. This one is way more sturdier, looks nicer, bigger, and has a nice feel.

Looks great, doesn't hold much so measure carefully
Color: Gray, Size: Rectangle
I got this organizer for my husband to keep his stuff by the door. While it's a little smaller than I'd hoped, it looks great in the entryway. It's super easy to snap together, but feels like the material could be damaged easily if you're not careful. He is able to store his keys, wallet, and sunglasses in it, and throws hit hat on top. Overall we are really happy with it.

Perfect
Color: Blue, Size: Square
Just what I needed. The size is perfect as I didn’t want anything too large to place my watches and other accessories inside near the corner of my desk. Its size is essentially 7x7, and the design is sleek compared to other organizer holders. I got the color in blue and it looks stunning with the rest of my setup. I’m unsure about other reviewers, but mine came safely and the leather walls are decently thick, so it’s not too flimsy when buttoned together which holds very securely. There are hole spaces at the bottom corners once assembled, so if you have super small items such as beads or really small jewelry, they could potentially fall out, but most of my items are large enough that won’t be of concern. If you have a wire charger near by, the holes could be used to charge your smartphone inside, which has its own practical usage. Overall, I’d definitely recommend it if you’re on a lookout for a sleek but compact organizer holder, and I personally will consider getting another one in the future for myself for other household belongings.
