Integrated Engineering IEINCK4 Turbo Inlet Pipe
The Integrated Engineering IEINCK4 Turbo Inlet Pipe is specifically designed for the Audi S4 and S5 models from 2017 to 2023, catering to those who have upgraded their 3.0L turbocharged engines with aftermarket components like ECU tunes and larger turbos. While the factory airbox and turbo inlet may suffice for stock power levels, they become significant bottlenecks when pushing for increased horsepower with aftermarket enhancements.
This turbo inlet pipe optimizes airflow, allowing your turbocharger to perform more efficiently and effectively. By pairing the IEINCK4 with an IE Cold Air Intake, you can eliminate the factory flow restrictions and maximize your engine's potential.
Key Features
- Engineered for maximum airflow, providing a 23% increase over the stock turbo inlet.
- Delivers 37.4% higher flow than stock when used with the IE carbon intake on a stock turbo.
- Achieves a remarkable 61.49% higher flow compared to stock when paired with the IE intake on a hybrid turbo.
- Features a 4" effective inner diameter cross-section for optimal performance.
- Inlet dimensions: 85mm on the inlet side, reducing to 66mm on the turbo side (prior to adapter plates).
- Can provide up to 19HP and 21ft-lbs of torque over stock when combined with the IE intake.
- Slip-fit retainer post design simplifies installation.
- Designed to support hybrid turbo flow requirements.
- Direct bolt-on compatibility with stock and popular hybrid turbos.
- Constructed from cast aircraft-grade aluminum for durability and reliability.
- CNC machined in-house to ensure precise tolerances.
- Maximized design for superior airflow characteristics.
- O-ring sealed turbo flanges provide a leak-free installation.
- Perfectly complements the IE Cold Air Intake.
