Pipercross Induction Kit Cold Air Intake for BMW M140i & M240i B58 (F20 F21 F22 F23) - High-Flow Tri-Layer Foam, Direct Fit

Pipercross Performance Intake System for BMW M140i and M240i B58

Give your B58-powered BMW the airflow it deserves. This Pipercross performance intake system frees up breathing on the M140i and M240i, delivering faster pedal response, a more eager mid-range and an addictive turbo soundtrack. Designed specifically for the 1 Series and 2 Series chassis listed below, it replaces the restrictive factory airbox with a high-flow, triple-layer open-cell foam filter and precision-engineered pipework for smooth, uninterrupted airflow.

Why enthusiasts choose this upgrade

• Stronger, more immediate response from low revs for effortless overtakes and sharper driveability
• Enhanced turbo spool and induction tone that brings the B58 straight six to life
• Vehicle-specific, bolt-on fit for the M140i and M240i with all required hardware and clear instructions
• Reusable, washable foam element with longer service intervals than cotton gauze alternatives
• Tri-layer filtration offers excellent engine protection while keeping restriction to a minimum
• Developed using flow bench testing to optimise mass airflow and reduce pressure drop
• Backed by a lifetime road-use warranty for long-term confidence

High-flow foam technology

Pipercross uses a progressive three-layer foam construction that captures debris in stages while maintaining high airflow. Coarser outer foam stops larger particles, the intermediate layer handles the bulk of the contaminants and the fine inner layer catches the smallest particulates. The result is reliable filtration with reduced intake resistance compared to many cotton and paper elements, giving your B58 a freer-breathing, more responsive feel along with a deeper, richer intake note.
