do88 Inlet Hose for EA888.4 Garrett (245hp)

Developed for direct drop-in installation on VAG 2.0 TSI EA888 Gen4 engines (MQB EVO platform).

Key Indicators

• 717 CFM at 0.1 bar / 1.45 psi pressure drop
  (587 CFM OEM)
  ➜ +22% more airflow

• More air to the turbocharger

• Lower back pressure

• Better turbo efficiency

OEM reference: 5WA129654A

Why is the inlet so important?

The efficiency of a turbocharged engine depends on:

• IAT (Intake Air Temperature)

• Vacuum before the compressor

• Available airflow

Insufficient flow before the turbocharger can lead to:

• Increased vacuum

• Higher wastegate duty

• Slower spool

• Lower efficiency

Colder air + less vacuum = greater air mass to the engine = real power gains.

Engineering Process

Development begins with:

• 3D scanning of the mounting space

• CAD design in SolidWorks

• Optimization of radii and angles

• CFD analysis

• Flowbench testing (Superflow SF1020)

The result is a real measurable flow, not marketing claims.

Construction

• 3D freeform silicone hose

• High-quality black silicone

• CNC machined turbo adapter

• Premium clamps included

• OEM+ fitment
