Application Details

ATP Parts 101304 is engineered for the exhaust manifold section that carries burned gases away from the engine and into the exhaust system. When the original manifold cracks or warps, exhaust leaks can develop at the engine bay and affect cabin air quality. This ATP exhaust manifold assembly restores the factory-style exhaust path on Honda Civic models and helps eliminate leak points at the manifold-to-exhaust connection. This part cross-references Bosch 16373 for the same application.

What It Helps Repair

  • Exhaust leaks at the manifold
  • Cracked or warped manifold surfaces
  • Hot exhaust gas entering the engine compartment
