Detailed Description

Motorad 1VS109 is engineered for Subaru engines that use VVT to manage cam timing, idle quality, emissions output, and fuel economy. The compact housing measures 3.81 in. long and 1.12 in. wide by 1.12 in. high, with a black connector and black body for OE-style service replacement. This VVT solenoid is listed for Subaru Legacy, Outback, Impreza, Forester, and B9 Tribeca applications, including intake-position listings where specified.

For buyers searching for a Subaru Legacy VVT solenoid, Subaru Outback VVT solenoid, or Subaru Forester intake solenoid, part number 1VS109 provides a fitment-based replacement path for the listed model years. It is also referenced against OE and aftermarket numbers 10921AA040 and 917246 for the same application.

Common Issues This Part May Address

• Check engine light related to VVT or cam timing control
• Rough idle caused by inconsistent oil control to the cam phaser system
• Reduced fuel economy from improper valve timing operation
• Higher emissions from delayed or incorrect cam timing response
• Engine performance concerns tied to a sticking or failing VVT solenoid

Installation Notes and Tips

Verify the connector style, terminal layout, and position before installation. This part uses a plug-in rectangular connector with a female connector body and male blade terminals, so matching the original electrical interface is important. Confirm whether your application calls for the intake position, especially on 2008-2009 Subaru Legacy and 2006-2007 Subaru B9 Tribeca listings. Inspect the engine oil condition and related passages during replacement, since VVT operation depends on clean oil flow.

Quality Assurance

MotoRad backs its engine management products with a limited lifetime warranty. The 1VS109 is built to perform under demanding operating conditions while supporting proper fuel economy and lower emissions through stable VVT control.
