Vehicle Fitment

• 2019-2023 BMW X2 M35i (2.0L L4 Turbo, Fuel Injected)

Fitment Notes

• These models share the same UKL2-platform B48 2.0L turbo M-Performance engine and air box. K&N's product page shows the X2 M35i as its primary title vehicle; the full multi-model fitment above is independently confirmed by two separate regional Amazon listings with matching data. This filter is specific to the M-Performance variants - it does not fit the standard (non-M) X2, 1-Series, 2-Series, or Countryman trims with smaller engines.

Product Description

The K&N 33-5111 is a direct-fit replacement panel air filter engineered for the shared B48 2.0L turbo engine found in the BMW X2 M35i, M135i, M235i xDrive Gran Coupe, and MINI Countryman JCW. Its layered cotton gauze media is designed to deliver higher airflow than the factory paper filter, helping this M-Performance 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 owners of these M-Performance BMW and MINI models looking to reduce long-term filter costs while keeping the factory intake setup. Given the number of shared-platform models this part covers, confirming your exact trim is recommended before ordering.
