The Radiator Cap for the BMW 428i will fit every coupe, convertible, and Gran Coupe, eliminating any guesswork. It is an excellent unit that is totally plug-and-play and which owners can trust mile after mile.

The BMW 428i Radiator Cap, which comes with a new gasket, creates a tight seal that prevents vapor loss. This helps avoid air pockets that can rob your car of power and keep coolant circulating at the correct boiling point. Thus, drivers can avoid any sudden spikes in temperature. Owing to tested metallurgy and a durable polymer insert, the BMW 428i Radiator Cap resists corrosion, vibration, and thermal cycling for years of reliable service, which translates to lower ownership costs and greater peace of mind on long road trips. Contrary to standard caps, the Radiator Cap features a calibrated vacuum valve that keeps the system topped up once things cool, a useful detail as it allows for smooth dawn start-ups and stable idle quality.
