BMW Z4 M E85/E86 S50B32 air filter ITG Profilter

Direct-fit Tri-Foam air filter for the BMW Z4 M (E85 Roadster and E86 Coupe) with the S50B32 engine. No trimming, no mods - drops straight into the OEM airbox.

ITG’s motorsport-proven foam construction holds dust-trapping oil, flows more air than stock, and sharpens throttle response. Ideal for fast-road use or track-day prep where reliability matters.

• Replaces OEM filter without modification
• Washable and reusable - lasts up to four times longer than paper filters
• Engineered for UK climate and road conditions
