Aluminum Adapter Blanking Plugs for BMW E46 E60 E61 E65 E83 E53

The Aluminum Adapter Blanking Plugs kit (Model BOP40) is a durable, aluminum solution designed to seal unused ports during BMW maintenance, such as when removing a cooler thermostat or replacing related components. Built for rugged use in diesel engines, these plugs help prevent leaks and contamination while saving you time and money by allowing you to replace a faulty part without replacing the entire assembly. The plugs arrive in a black aluminum finish for lasting corrosion resistance and a clean engine bay appearance.

Designed to fit a wide range of BMW models, this kit is specifically intended for diesel vehicles (NOT PETROL) and is compatible with engines and series listed in the product details. The combination of lightweight aluminum, precise fitment, and a reliable seal helps keep cooling and related systems running smoothly between service intervals. OEM references 11717789999 and 11717804379 ensure the plugs align with the intended diesel engines and fit multiple BMW platforms described in the listing.

Trust and compatibility are built into every unit, with the kit formulated to meet the demanding conditions of BMW diesel systems across the listed series. The packaging notes and model details reflect careful alignment with the engines these vehicles use, helping you avoid over- or under-sealing and ensuring a secure, irritation-free installation process.
