FAQ-ABS Sensor - 27540AG100
Q1: Which specific Subaru models and years is part number "27540AG100" compatible with?
A: This part is a cross-model universal component, detailed to fit the following models:
Subaru Forester: 2008-2012 model years
Subaru Impreza: 2008-2010 model years (including IMPREZA, IMPREZA R, IMPREZA SPORT)
This indicates that between 2008 and 2012, Subaru's Forester and Impreza lines shared the same ABS sensor design.
Q2: What are its physical installation specifications (connector, harness, bolt holes)?
A: Its core physical specifications are: 1 rectangular male connector, 2 terminals, a harness length of 830 mm (approx. 30.25 inches), and mounting on the spindle via 3 bolt holes. These specifications are key to ensuring it can be installed directly and correctly on compatible vehicles.
Q3: Does the product package include all accessories required for installation?
A: No, it does not. The product specifications clearly state "Dust Shield Included: No" and "Mounting Hardware Included: No." This means buyers need to prepare or reuse the vehicle's original mounting bolts separately. If the original sensor has a separate dust shield, it also needs to be handled independently (cleaned and reused or purchased separately).
Q4: What is its relationship to part number "27540SC010" (also for 2008-2012 Forester)? Are they interchangeable?
A: Both are compatible with the 2008-2012 Subaru Forester and have highly similar physical specifications. The main differences are:
27540AG100 has a broader compatibility range, also fitting the 2008-2010 Impreza.
27540SC010, according to its page information, is listed specifically for the Forester.
They are likely functionally compatible and interchangeable, which may reflect the same part having different suppliers or internal numbers. However, the safest practice is always to prioritize matching the actual part number stamped on the old component.
Q5: As an aftermarket replacement part, how is its quality assured?
A: The product description states it is a replacement for the original equipment manufacturer (OEM) part number 27540AG100 and is "manufactured to meet or exceed OEM standards for durability and reliability." This indicates it is a high-quality aftermarket part manufactured by STANDARD MOTOR PRODUCTS, designed to match the performance and specifications of the original factory part, providing a reliable repair option for vehicles around 10-15 years old.
