The S55 twin-turbo engine that powers the BMW M2C / M3 / M4 F8X is equipped with quite restrictive inlet pipes to the turbochargers and reducing the restrictions on the turbo inlet side is of great importance on any performance build.
With the performance turbo inlets DO88 offers a solution that minimize the air flow restrictions just before the turbochargers!
To get an exact 3D-model of the available space to design the turbo inlets, DO88 did a detailed 3D-scan of the M3 Competition engine bay. With the help of this 3D-scan model they could design new turbo inlets that improves the air flow in this extremely limited space.
The DO88 final design is a package with front and rear turbo inlets. The rear turbo inlet consists of a custom designed aluminum pipe with a welded CNC machined turbo connection radius flange. The front turbo inlet consists of a 3D freeform designed steel wire reinforced silicone hose that connects to the turbocharger using a CNC machined radius adapter. DO88 includes matte black hose clamps for a clean stealthy look.
