K&N 33-3071 High-Flow Air Filter for 2017-2022 Alfa Romeo Giulia/Stelvio 2.0L L4

Vehicle Fitment

• 2017-2022 Alfa Romeo Giulia (2.0L L4 Turbo, Fuel Injected)
• 2018-2020 Alfa Romeo Stelvio (2.0L L4 Turbo, Fuel Injected)
• 2022-2025 Alfa Romeo Stelvio (2.0L L4 Turbo, Fuel Injected)

Fitment Notes

• Stelvio fitment shows a gap for the 2021 model year across independently confirmed sources, likely due to a mid-cycle running change; owners of a 2021 Stelvio should confirm compatibility using their VIN before ordering. Giulia and Stelvio share the same 2.0L turbo engine and air box on the Giorgio platform, which is why one part number covers both.

Product Description

The K&N 33-3071 is a direct-fit replacement panel air filter engineered for the shared Giorgio-platform 2.0L turbocharged four-cylinder found in the Alfa Romeo Giulia and Stelvio. Its layered cotton gauze media is designed to deliver higher airflow than the factory paper filter, helping the turbo 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.

This filter is a practical, reusable upgrade for Giulia and Stelvio owners looking to reduce long-term filter costs while keeping the factory intake setup. Given the split year ranges on the Stelvio, confirming your exact build year is recommended before ordering.
