Our manifold features a Bar&Plate design air-water core, which incorporates densely stacked cooling fins, offering great heat transfer. The core is precisely 127 mm (5 inches) thick, maximizing its effectiveness for this specific application. The core is remarkably 62% larger than stock! Both the air and water fins characteristics have undergone careful evaluation to achieve the ideal balance between optimal cooling and airflow.

As replacement for the stock plastic intake pipes, we designed large, smooth carbon fiber tubes. These begin with a diameter of 105mm (4.1 inches) at the air filter end and taper down to 3.25 inches, matching our custom turbo inlets. Attached to the carbon tubes is our large, custom-designed air filter. This filter features a densely woven cotton gauze, ensuring clean airflow. Designed for durability and efficiency, the filter is washable and reusable, promoting optimal performance and an extended service life.

Our design distinguishes itself as we've taken the additional step of developing custom turbo inlets that replace the OE's restrictive plastic inlets. The original inlets feature connection sizes of only 61mm and 72mm. In contrast, our custom aluminum casting turbo inlets has significantly larger 83mm connections.

Our charge pipe system is 15 % less restrictive than the stock version, significantly improving flow and power potential. By replacing the fragile plastic with robust cast aluminum Y-pipe which greatly enhancing durability and preventing costly failures. The design features optimized transitions to minimize restrictions and improve airflow. We use CNC-machined turbo and throttle adapters to guarantee a leak-free operation, and a larger throttle body quick-disconnect to match the throttle's internal diameter. For added functionality, our charge pipe includes two 1/8 NPT ports for methanol injection or boost pressure sensors, with plugs provided for those who opt not to use these features. Testing shows our charge pipe achieves a flow of 960 CFM @ 150mbar (2.17psi), offering a significant improvement over the OEM's 835 CFM.

The front intercooler radiator upgrade began with a total overhaul, prioritizing durability and performance. By eliminating plastic components in favor of sturdy aluminum for the end tanks, the core, and CNC-machined ports, and ensuring everything is TIG-welded, our cooler provides durability and long-term performance. The introduction of a Quad pass design improves cooling, with the coolant passing through the cooler's core four times for maximum efficiency. We managed to increase the core volume by 39% and the external tube area by 9%, while simultaneously integrating a Quad pass flow for the coolant.


Oil Coolers

The S58 engine features an engine oil cooler that is mounted horizontally beneath the front central radiators. The original uses a Tube & Fin core, which can easily get damaged by stone chips or other road debris. Because of its design and location, it's not rare for the oil cooler to start leaking from accumulated damage. Our design increases the active cooling area (+14%) and core volume by 57% compared to the original oil cooler. While the robust Bar & Plate core will withstand road debris and stone chips much better.

There's also a transmission oil cooler which we've improved, increasing its volume by 71% and the cooling surface area by 50% while maintaining similar oil pressures is the result. We also upgraded the tubes with harmonica tubes featuring internal channels, ensuring optimal cooling efficiency. It also increases the system's cooling capacity with a 42% (8,5 dl vs 6 dl) rise in oil volume. Our cooler uses a dual-pass design which means the fluid stays in the cooler for longer, ensuring more heat is dissipated.
