Drop-in Sports Filter for BMW Z4 E89 35i 05/2009 onwards by Pipercross

Give your Z4 the breathing it deserves with this UK-built Pipercross drop-in panel filter. Designed to slide straight into the factory airbox on the BMW Z4 E89 35i from 05/2009 onward, this serviceable foam element boosts intake flow, sharpens throttle response and subtly enhances induction sound while maintaining outstanding engine protection.

Why this upgrade makes a difference

• Direct-fit panel insert for the Z4 E89 35i airbox. No cutting. No extras needed
• Up to 30 percent more airflow compared with disposable paper elements for stronger mid-range pull
• Three-layer foam matrix delivers excellent dust capture without choking flow

Engine-safe filtration with real-world performance

Pipercross uses a progressive foam structure that filters in stages. The outer layer stops the big particles, the centre layer deals with the bulk of airborne debris and the inner layer refines the final airflow to the intake. The result is strong, stable flow across the rev range with dependable protection in British road conditions.

What you will notice

• Crisper throttle pick-up and smoother acceleration
• A cleaner, slightly richer induction tone under load
• Consistent performance over time thanks to high dirt-holding capacity
