BMW X3 28i F25 and BMW X4 28i F26 Performance Panel Filter Upgrade – aFe Pro DRY S 31-10257

Give your BMW’s intake system a simple, effective breathing upgrade with the aFe Pro DRY S panel filter. Designed as a direct swap for the factory element, this serviceable dry filter increases airflow while maintaining excellent particle capture. No oiling, no tuning, just a high-quality filter element built to fit the original airbox and keep performance consistent mile after mile.

Part number 31-10257 is engineered for the BMW X3 28i xDrive F25 and BMW X4 28i xDrive F26 with the N20 2.0 turbo petrol and the early N52 3.0 straight six. We run this filter ourselves and our customers love the crisp fit, robust construction and the convenience of quick cleaning and re-use.

Why this panel filter is a smart upgrade

  • Dry three-layer synthetic media for easy maintenance and strong dust control
  • High-flow design helps the engine breathe more freely without ECU mapping
  • Progressive sealing lip conforms to the airbox for a reliable, leak-free fit
  • Durable polyurethane frame for OE-style stability and long service life
  • Wash, refit, repeat for long-term value and reduced waste
  • Drop-in replacement for the stock filter element in the factory airbox

Technical highlights

  • Pro DRY S media with three progressive layers
  • Approx. 25 mm deep arc-shaped pleats with a 27-pleat count to maximise surface area
  • Full perimeter polyurethane construction for strength and heat resistance
