BMW G8x M3 and M4 Intake Filter Upgrade for the S58

Give your G8x a serious breathing advantage with this flagship Plus-series air filter upgrade from Pipercross. Designed for the S58-powered BMW M3 and M4, these high-flow foam intake elements replace the factory paper inserts inside the original airbox and deliver stronger construction, improved airflow and long-term durability for both road and track use.

Why this upgrade stands out

• 1 mm steel reinforcement frame for exceptional rigidity under high CFM demands. Built to stay stable at speed and under load.
• Effective flow area increased by 22.1 percent versus the regular mesh design used in standard versions, helping your S58 breathe more freely.
• High-quality multi-layer foam media that supports strong filtration performance while promoting rapid airflow.
• Direct-fit drop-in elements for the OEM air box. No cutting, no drilling, no coding and no remap required.
• Enhanced durability from the stronger frame architecture, resisting deformation over time.
• Sharper throttle response and a more purposeful induction note compared with stock paper filters.
