The Camshaft Position Sensor for the Subaru WRX STI provides the engine computer with accurate real-time camshaft data so it can control ignition timing quickly and achieve smooth power delivery every time you press the throttle. The Camshaft Position Sensor, with the help of a crank detector in the Subaru powertrain, records shaft angle every millisecond to make sure fuel and spark are in harmony. Thus, the WRX STI, which is rally bred, offers a hard launch and smooth cruising. This module fits across multiple WRX STI generations, so you can confidently swap the unit in. The Camshaft Position Sensor relies on heat-resistant magnets and precise Hall effect circuitry to withstand vibrations commonly associated with turbocharged Subaru engines. This robust design conveys dependable RPM feedback to the control module. As a result, any Subaru performance mill can re-tune valve timing in a jiffy, trim emissions, and stretch fuel economy without losing speed. The Camshaft Position Sensor prevents misfires that could otherwise cause the Subaru to stall in traffic or require lower speed when passing, increasing safety as well. Pushing and seating the Camshaft Position Sensor restores the crisp idle and steady pull a driver expects from a WRX STI. Its factory-style connector and molded alignment tabs make installation easy. Independent testing revealed that the recent Subaru version of this Camshaft Position Sensor remains clean at redline, which distinguishes it from many other parts on the market for the WRX STI. As a result of such stamina, the sensor remains a smart factory-grade upgrade for enthusiasts who want their WRX STI performing flawlessly every lap.
