About this product
The Integrated Engineering Polymer Air Intake System replaces the factory airbox on the Audi B9 and B9.5 A4 and A5 2.0T with a rotomolded polymer airbox built around a 5 inch air filter and an integrated velocity stack. IE measured consistent airflow gains of up to 70 CFM over stock across its flow bench, and reports up to 10 to 20 additional horsepower when the intake is paired with a matching ECU tune.
The kit mounts to the factory locations with no drilling, using all stainless hardware, and keeps the high- and low-pressure air zones separated the way the factory airbox does.
Important Compatibility Information
- Built for Audi A4 (2017-2024) and A5 (2018-2024), B9 and B9.5, 2.0T.
- Does not fit Rest-of-World vehicles equipped with a MAF sensor.
Construction
- Rotomolded polymer airbox with consistent wall thickness and strong corners
- 5 inch air filter and integrated velocity stack
- Separate high-pressure and low-pressure air zones
- Factory-style mounts - no drilling or permanent modification
- All stainless hardware
- Powder-coated aluminum filter plate and velocity stack
- Stainless, laser-etched logo plate

Frequently Asked Questions
Do I need a tune to see power gains?
Yes. IE's reported 10 to 20 hp gain is measured with software; the intake alone is a flow and sound upgrade without a matching ECU tune.
Does this fit the B9.5 facelift?
Yes. This intake covers both the original B9 and the facelifted B9.5 A4 and A5.
Will this fit a Rest-of-World A4 or A5?
Not if your car uses a MAF sensor. IE states this intake doesn't fit ROW vehicles equipped with one.
Do I need to modify anything to install it?
No. It mounts to the factory locations with the included stainless hardware, with no drilling.
Is there a carbon fiber option?
The airbox itself is polymer; a separate carbon fiber intake lid is available for the cover.
