K&N 57-0510 Cold Air Intake/Induction Kit for BMW MINI One D 1.4L Diesel R50 R53 (2003-2006) - Performance Air Intake System with Reusable High-Flow Cotton Filter, Direct-Fit Bolt-On Upgrade, CAI Replacement for Factory Airbox

K&N 57-0510 Intake Upgrade for MINI One D 1.4 Diesel R50 R53 2003 to 2006

Unlock smoother breathing and a more eager response from your 1.4-litre diesel with the K&N 57-0510 induction upgrade. This model-specific kit replaces the restrictive factory airbox on the MINI One D and delivers a cleaner, less turbulent airflow path. Expect crisper throttle feel, a sportier induction note and a drivability uplift that makes everyday journeys more engaging.

We have fitted this setup on our own builds and customer cars and it consistently impresses. The serviceable K&N cotton gauze element is engineered for long-term use, so you can wash, re-oil and refit rather than throw away. It is a smart, simple, bolt-on upgrade for MINI owners who want real-world gains without hassle.
