Throttle Position Switch - E30 325e/325i, E28 528e, E34 525i M20
Throttle Position Switch that is critical for M20 performance
This part is listed by BMW as BMW part number 13631710559 (13 63 1 710 559) and is described as the throttle position sensor on the M20 engine in E30 325e/325i, E28 528e, and E34 525i (1989-1990).
Throttle position is monitored by this sensor mounted underneath the throttle body on the M20 engine. The ECU relies on this sensor to determine which fuel, ignition, and torque maps to use. If the ECU is not seeing good data, or the throttle is out of position, it will restrict performance. The ECU will not deliver full power if it doesn't see full throttle, right?
This part is manufactured by an aftermarket supplier of European auto parts, including many sensors. While not carrying OEM status, this part follows the design of the original very closely and uses similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. The brand may even be OEM to another manufacturer besides BMW. This aftermarket brand has a two year warranty - the same as Genuine BMW and OEM brands.
