aFe MagnumFLOW Pro DRY S Replacement Filter Element 31-10226 for BMW 3.0 turbo models

Looking for a simple intake upgrade that actually works on your F-series BMW turbo six. The aFe MagnumFLOW Pro DRY S replacement element, part number 31-10226, is a high-flow, oil-less drop-in insert that fits the factory airbox and improves breathing for sharper throttle response and stronger mid-range pull. It is cleanable, reusable and designed to outflow the standard paper element while maintaining excellent engine protection.

The three-layer synthetic media delivers 99.2% filtration efficiency and needs no oil, so there is no mess and no risk of fouling sensors. Rounded open pleats maximise surface area, the full urethane frame adds durability and the progressive bump seal ensures a precise, leak-free fit every time. Wash it with mild soap and water, refit and enjoy long service intervals. A cost-effective performance intake filter upgrade for daily drivers and enthusiast builds alike.

We run this aFe element on our own N55 cars and customer builds and it has been faultless. Owners report crisper pick-up, smooth drivability and hassle-free cleaning thanks to the dry synthetic media. If you are searching for a BMW F30 F31 F32 F33 F34 F36 F87 intake filter upgrade that fits the standard airbox, this is the proven choice.
