Product Overview

Restore the seal after inspecting or replacing exhaust risers

Regular inspection of exhaust system risers and manifolds is an important step in maintaining separation of cooling water and exhaust gases. Replacing the gaskets after these inspections is the best practice approach. Sierra makes replacing the exhaust elbow gaskets easy for do-it-yourselfers and technicians by packaging exhaust elbow gaskets in pairs. These gaskets meet or exceed factory specifications and match OEM openings and bolt hole patterns to ensure a quick installation. Stay on top of the exhaust system and maintain the seals using Sierra gasket kits.

Key Features

  • Meets or exceeds OEM specifications
  • Sold in pairs (2 of Sierra p/n 18-0672)
  • Fits GM based V6 and V8 engines with center rise outlet exhaust manifold
