Throttle Position Switch, BMW - 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 is a Genuine BMW throttle position sensor with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
