Detailed Product Overview

The line is built to handle the elevated temperatures found around the turbocharger assembly while maintaining a secure connection at the inlet and outlet.

Installation Notes and Tips

Verify the inlet and outlet fitting styles before installation: bolt-on inlet and push-in outlet. Confirm the centerline length of 8.75 in. (222 mm) matches the original routing on the vehicle. Clean the mating surfaces and inspect nearby turbocharger components for heat damage, oil residue, or hardened seals before installing the new line.
