Enhance your B58 engines performance with the MERA do88 Charge Cooler Manifold!

The do88 solution

This performance charge cooler is part of our MERA range! MERA as in more, means more cooling, better airflow, more performance. Simply, MERA!

Garrett Motorsport core
Our MERA manifold features a Bar&Plate design air-water core, crafted by esteemed Garrett Motorsport, setting the industry standard for quality and performance. Its construction incorporates thin, densely stacked cooling fins, which offer exceptionally efficient heat transfer. The core is precisely 102 mm (4 inches) thick, maximizing its effectiveness for this specific application. Both the air and water fins´ characteristics have undergone meticulous evaluation to achieve the ideal balance between optimal cooling and airflow.

Innovatively designed cast end tanks
The charge air and cooling water are evenly distributed across the core through carefully designed, cast end tanks. The development of these end tanks involved a comprehensive process, including 3D-scanning, multiple design iterations followed by Computational Fluid Dynamics (CFD) analysis and 3D-printing, before arriving at the finalized prototype. We opted for cast end tanks over CNC-machining. Casting allows complex shapes that better serves the desired function. To us, maximum performance supersedes the bling factor!

Engine Cover Compatibility
A goal during the development of our do88 manifold was to keep compatibility with the standard engine cover. It goes without saying, many enthusiasts prefer to maintain the original appearance of their engine bay if possible. With this in mind, we invested significant effort to design a charge air cooler that not only makes a massive performance upgrade, but also have the possibility to use the engine cover. We managed the challenging task of accommodating our manifold under the engine cover.

Moreover, it is possible, with modifications, to also integrate our auxiliary fuel rail. To do this, the sound-dampening material beneath both the engine cover and the hood must be removed. Additionally, the standard engine cover mounting pins must be replaced with longer ones, which we include in our kit. Note that installing the engine cover in this elevated position brings it very close to the hood; slight trimming or reshaping of the hoods support structure can be done to increased clearance. We have verified this compatibility exclusively on the BMW 340i F30/F31 models.

The devil is in the detail and to date, this unique feature sets the do88 kit apart from the competition. High performance builds tend to be made by enthusiasts that value the appearance equally as high as the sheer performance without compromise.
