Racingline High-Flow Replacement Air Filter – Audi R8 4.2 Gen.1 (VWR119042)
The Racingline High-Flow Replacement Air Filter is one of the simplest and most cost-effective upgrades available for the Gen.1 Audi R8 4.2 V8. Designed as a direct fit for the factory airbox, it replaces the restrictive paper element with a higher-flowing filter that allows the engine to breathe more freely, with no changes under the bonnet and no modifications required.
The standard paper filter fitted from the factory is a known restriction. Air has to work harder to pass through it, which limits how much clean, cool air reaches the engine. By swapping it for the Racingline filter, you reduce that restriction and give the 4.2 V8 a more consistent supply of air across the rev range.
What the filter does for your R8
Because the R8’s 4.2 V8 is a naturally aspirated engine (it relies on atmospheric pressure rather than a turbo or supercharger), it depends entirely on how well it can draw air in. A freer-flowing filter helps the engine fill more efficiently, which typically results in a small but measurable improvement in throttle response, power and fuel efficiency. It is a sensible first step for any owner looking to refine the way their car performs, rather than chasing a dramatic transformation.
- Direct OEM replacement that drops straight into the factory airbox with no modifications required
- Higher airflow than the standard paper filter for improved engine breathing
- Quality filtration to protect the engine from harmful particles
- Subtle gains in power, throttle response and economy
- Cost-effective upgrade with no remap or supporting modifications needed
