Exhaust Valve Actuator for 4P

Shadow 4-pin exhaust valve actuator with BMW-matching body and mounting points

SW70004-00 is Shadow's 4-pin exhaust valve actuator, made for use with aftermarket valve controllers.

Once a valve controller is installed, the valve opens and closes often, depending on the situation and the selected mode, and the motor works through many more cycles.

Key points of SW70004-00:

・Same body dimensions and mounting points as BMW
・4-pin connector, with signals that follow BMW's automotive specification
・Reinforced mechanism and better weather resistance, for a more durable actuator
・Suited to frequent opening and closing under a controller
・Replaces a failed OEM motor directly

The body dimensions match BMW's, including the mounting points. If the OEM motor fails, this actuator can replace it directly.

A 4-pin connector, with signals that follow BMW's automotive specification.

The housing is joined by high-frequency bonding, and the gear train inside is reinforced. Built on the OEM design, it strengthens the mechanism and weather resistance for long, high-torque operation. We aim for OEM-level quality.

It works with the Shadow Electronic Exhaust Valve Controller II-MODIFIED and serves as the motor accessory for aftermarket valve controllers. If the OEM motor fails, it can replace it directly.

SW70004-00 can replace motors with the following BMW OEM 4-pin part numbers. Check the part number first. Actual fitment still depends on model, model year and configuration.
