Did not disappoint!
Perfect Fit: Bolted right up to the engine block without any shimmying or modification needed. ​Strong Crank: The motor sounds powerful and turns the engine over significantly faster than my old, dying unit. Once hooked up, the car fired up instantly on the first turn of the key. No grinding, no clicking, just a smooth, high-torque start. Price: A lot more cheaper then your average auto parts stores. ​Build Quality: The solenoid connections are solid and the threads were clean. Packaging: The box arrived on time but a bit beat up, but the starter itself was well-protected in bubble wrap and undamaged.
