Racingline High-Flow Air Filter- Audi S4/S5 3.0T (B8)

Racingline High-Flow Air Filter – Audi S4/S5 3.0T (B8) – VWR1140S4

The Racingline High-Flow Air Filter is one of the simplest and most cost-effective upgrades you can make to your Audi S4 or S5 (B8) 3.0T. Designed as a direct replacement for the standard paper filter, it drops straight into the factory airbox and allows your supercharged V6 to draw in more clean, cool air with less restriction.

The original paper filter does its job, but it is known to limit airflow as it loads up with dust and debris. By swapping it for the Racingline filter, you remove that bottleneck without having to change any other part of your intake system. There is no cutting, no remapping, and no special tools required.

What This Filter Does

Better airflow into the engine means the 3.0 TFSI can breathe more freely, particularly under harder acceleration when the supercharger is working hardest. The gains are modest but genuine: a small lift in throttle response, a slight improvement in power and torque, and often a minor benefit to fuel economy during everyday driving. It is an honest upgrade rather than a dramatic transformation, and it pairs well with other intake and software modifications further down the line.

Unlike many aftermarket filters, this one is engineered to maintain proper filtration. Your engine still gets the protection it needs from dust and particles, so you are not trading longevity for airflow.

Key Benefits

• Direct fit: drops straight into the standard B8 S4/S5 airbox with no modifications
• Higher airflow: reduces the restriction of the OEM paper element
• Cleanable and reusable: a long-life filter that can be serviced rather than thrown away
• Excellent value: one of the most affordable performance upgrades available for the 3.0T
