do88 Porsche 911 Turbo / Turbo S (991) Inlet Hoses for Turbo

do88 proudly presents the world's first genuine high-flow turbo inlet hoses for the Porsche 991.1/991.2 Turbo. It was a real engineering challenge, the lack of available space made it genuinely difficult to build a set of hoses that could outflow the stock plastic pipes at all, but do88 succeeded, though in some smaller, non-sensitive areas the hoses have no clearance and will lightly push or rub against surrounding components.

The hoses feature a 2.5in (63mm) inner diameter at the smallest point, with smooth flow transitions and a very smooth internal surface for the best possible airflow. Excellent thermal properties mean the hoses won't absorb heat from the engine, and stainless steel wire reinforcement eliminates the risk of implosion under high boost. The numbers: 31% higher airflow on OEM turbos, climbing to 50% higher with upgraded turbos. do88's own words capture it best: this is an improvement no test figures can fully explain, it genuinely has to be felt behind the wheel.

Please select your turbo compressor housing size at checkout: OEM 51.5mm, or confirm your specific upgraded turbo spec with your supplier.

Note: as of July 2026, a new Jet Pump valve is no longer included in this kit, the original valve must be reused during installation (see step 36 of the installation guide).
