Storch PLJ MAF Kit - BMW 5 Series E28 520i 1985-1987 / E28 525e / E34 520i 1987-1990 (PLJ-04-083-5)

Storch PLJ hot-film MAF kit for the BMW 5 Series E28 520i 1985-1987 / E28 525e / E34 520i 1987-1990. Replaces the factory flap-type air flow meter with a modern hot-film sensor for a larger intake cross-section, sharper throttle response and more power across the rev range. Made in Germany by Storch Vehicle Electronics.

The PLJ series MAF-sensors differ from the factory-installed air flow meters in that they do not have a throttle valve but instead measure the airflow using the hot film principle. This provides a significantly larger cross-section for the intake air. Combined with the fast and modern evaluation electronics, this leads to increased performance.

The engine control unit (ECU) is always provided with accurate values, which prevents any increased strain on the engine components.
