“Other” encompasses diverse non-drivetrain and body-specific components, typically residing within the interior, engine bay, or chassis. These parts facilitate auxiliary functions like fluid reservoirs, wiring harness connectors, vacuum lines, and specialized mounting hardware. Technical features vary widely, ranging from material composition optimized for temperature and chemical resistance to precise dimensional tolerances for secure fitment. Many items are vehicle-specific, demanding correct part number verification for compatibility. Installation often requires specialized tools and adherence to manufacturer torque specifications. Failure can manifest as fluid leaks, electrical malfunctions, or component instability.
