Dorman 03418 Turbocharger Stud

Dorman 03418 is a turbocharger stud built to match the fit and function of the original hardware on specified vehicles. Made from steel with a black phosphate finish, it is engineered for reliable fastening in turbocharger applications on Mazda 3, Mazda CX-7, and Mazda 6 models.

Key Features

  • Direct replacement turbocharger stud for OE-style fit and function
  • Steel construction for strength and durability
  • Black phosphate finish for added corrosion resistance
  • M10x1.5 thread size with coarse threads on both ends
  • 14 mm hex size for serviceability
  • Designed for Mazda turbocharger applications, including Mazda 3, Mazda CX-7, and Mazda 6

Detailed Description

This Dorman turbocharger stud is engineered for vehicles that require an M10x1.5 fastener with a 44.5 mm overall length, 12.7 mm thread length on one end, and 24.5 mm thread length on the other. The steel body and Grade 9.8 specification support secure clamping in high-heat turbocharger mounting locations. Dorman 03418 is a practical OE-style replacement for turbocharger service on 2007-2013 Mazda 3, 2007-2012 Mazda CX-7, and 2006-2007 Mazda 6 applications. This part cross-references Mazda OE number L3K913146A for the same application.

Common Repair Uses

  • Replacing a damaged or stretched turbocharger mounting stud
  • Restoring proper turbocharger-to-manifold fastening
  • Addressing exhaust leaks caused by worn turbo hardware
  • Repairing stripped or corroded threaded connections
  • Supporting service work on Mazda turbocharger assemblies

Installation Notes and Tips

Verify thread size, length, and hex access before installation. Clean the threaded holes and mating surfaces thoroughly so the stud seats correctly and the nut can clamp evenly. For Mazda 3, Mazda CX-7, and Mazda 6 turbocharger repairs, confirm the original hardware specification matches M10x1.5 before assembly.

Quality Assurance

Dorman designs this stud to match original part fit and function using quality materials for dependable performance. The black phosphate steel construction and Grade 9.8 hardware specification support consistent service in demanding turbocharger environments.
