Sakura A-30940 Air Filter for BMW 3 Series (F30, F31) 318d & 320d | Premium Soft PU Frame Intake | Replaces BMW 13718511668

Maintain the peak performance and fuel efficiency of your sport sedan with the Sakura A-30940 Air Filter, designed for the BMW 3 Series (F30). In high-compression diesel engines, intake air purity is vital to prevent carbon buildup and protect the turbocharger’s delicate compressor wheels. This filter provides a high-density barrier against microscopic road dust and industrial pollutants, ensuring your BMW continues to deliver its signature throttle response.

The A-30940 features a high-grade Soft PU (Polyurethane) Frame. Unlike rigid plastic filters, the Soft PU frame acts as a continuous integrated gasket. When installed, it compresses to form a vacuum-tight seal against the airbox housing. This specialized construction is essential for the F30 engine bay, as it effectively absorbs engine vibrations and prevents “dirty air bypass,” which can contaminate the Mass Air Flow (MAF) sensor and lead to “Check Engine” lights or reduced fuel economy.
