Say goodbye to messy spills and overflows when refilling your washer fluid. The BMW No-Spill Washer Fluid Funnel is engineered specifically to slip neatly into BMW washer fluid filler caps that have a neck diameter of 39 mm, providing a snug, stable fit. Once in place, gaps at the neck of the funnel allow washer fluid to flow freely into the reservoir while keeping the funnel securely seated.
✅ Precision 39 mm fit — designed to match the standard BMW filler-neck dimension
✅ Compatible with BMW model year 2010+ — designed for vehicles with the duct-style filler neck, where washer fluid is not directly visible when looking into the filler cap.
✅ Flow-through neck — gaps in the funnel neck let fluid pass easily into the reservoir without airlocks or splashing
✅ Stable hold — the snug collar keeps the funnel firmly in place during pouring
✅ Clean, spill-free refill — prevents messy drips onto engine bay plastics or paintwork
