K&N 33-3032 High-Flow Right Air Filter for 2010-2015 Audi RS4/RS5 4.2L V8 F/I

Vehicle Fitment

• 2010-2015 Audi RS5 (B8, 4.2L V8, Fuel Injected) - Right side filter
• 2012-2015 Audi RS4 Avant (B8, 4.2L V8, Fuel Injected, Europe/RoW market) - Right side filter

Fitment Notes

• These RS4/RS5 4.2L V8 models use two separate air filters - this is the RIGHT side filter only (33-3032); the LEFT side filter (33-3031) is required as well for a complete replacement. K&N's own product-page title shows a shorthand "2013-2015" range, but K&N's full vehicle-specific fitment listing (confirmed across its US, UK, and EU sites, plus independent retailers) shows the complete 2010-2015 range.

Product Description

The K&N 33-3032 is a direct-fit replacement panel air filter engineered for the right-side air box of the 2010-2015 Audi RS4/RS5 with the high-revving 4.2L V8. Its layered cotton gauze media is designed to deliver higher airflow than the factory paper filter, helping this naturally aspirated engine breathe more freely while continuing to trap the dirt and debris needed to protect it over the long term.

Rather than replacing a disposable paper filter every 12,000-15,000 miles, this filter can be cleaned and reoiled, typically going up to 75,000 miles between services under normal highway driving. It installs directly into the factory air box using the stock mounting points, so no cutting, drilling, or intake modifications are required.

Because the RS4/RS5's 4.2L V8 draws air through two separate air boxes, this right-side filter should be paired with K&N's left-side filter (33-3031) for a complete, matched replacement. Together they're a straightforward, reusable upgrade for owners looking to reduce long-term filter costs while keeping the factory intake setup.
