Product Description

The K&N 33-2270 is a washable, reusable panel air filter engineered as a direct drop-in replacement for the supercharged 1.6L engine in the first-generation MINI Cooper S. Built from layered, oiled cotton gauze, it's designed to improve airflow into the supercharger intake path while maintaining strong filtration.

As a reusable filter, the 33-2270 is built to last the life of the vehicle rather than requiring periodic replacement, needing only occasional cleaning under normal driving conditions. It's emissions legal in all 50 US states, won't void the factory warranty, and is backed by K&N's 10-Year/Million Mile Limited Warranty.

Given the Cooper S's forced-induction setup, improved intake airflow can be especially noticeable on this platform, making the 33-2270 a popular upgrade for owners looking to sharpen throttle response on both stock and modified supercharged builds.
