Audi Abt AS400 B6 Airbox/Duct / Engine Cover

Fitment and Compatibility

This ABT AS400 airbox/duct engine cover fits the Audi B6-generation platform. Confirm your specific model’s engine bay layout matches ABT’s AS400 fitment before ordering, since ABT designs its intake components for specific engine codes, not universally across every B6-era engine option.

Part Overview

ABT is a well-known Audi tuning brand, and the AS400 airbox system is one of their intake upgrade products, designed to improve airflow over the factory airbox while also serving as a styling upgrade for the engine bay.

Condition and What’s Included

Inspected for crack-free plastic and duct seal integrity before listing.

Installation Notes

Airbox and duct swaps are a moderate DIY job — removing the factory airbox, transferring or replacing the air filter, and securing the new unit’s mounting points and intake ducting.

OEM vs Aftermarket

Since this is a performance aftermarket part rather than a factory OEM airbox, the main consideration is whether the AS400’s specific engine code compatibility matches your car — confirm this with us before ordering.

Shipping and Support

Ships boxed with protection for the intake ducting.

Warranty and Returns

Covered under our 30-day return window for condition and fit as described; confirm engine code compatibility with us before ordering since aftermarket intake systems are engine-specific.

Why Buy This From Us

We confirm ABT’s specific engine code fitment before listing rather than assuming “B6-compatible” covers every engine option on that platform.
