Product FAQ

This unit references OE numbers including 11657790994, 731877-0001, and 731877-0003. Verify your specific vehicle's required number before ordering.

Common signs include excessive exhaust smoke, loss of power, unusual whining noises, or oil leaks around the turbo housing. Inspect for visible damage or bearing play.

Replace the full unit if the compressor or turbine wheels are damaged, the housing is cracked, or if internal bearing wear is severe. Component repair is only viable for minor CHRA issues.

Inspect the intake and exhaust piping for debris, check oil lines for blockages, and ensure the actuator related hardware moves freely. Clean the engine bay to prevent contamination during installation.
