BMW B58 G20 M340i / G22 M440i / G42 M240i Cold Air Intake

The Palenon Performance B58 cold air intake is a full replacement for the restrictive factory intake on G-chassis M340i, M440i and M240i models, built for more airflow, sharper throttle response and a louder turbo spool.

Why you need it

Palenon quotes around +15 wheel horsepower without additional tuning (results vary with tune and fuel), plus quicker response and the turbo sound you can actually hear under hard acceleration.
