MANIFOLD-EXHAUST (Hyundai HN3943871)

A damaged exhaust manifold can allow combustion gases to escape before reaching the catalytic converter or muffler. Hyundai lists this part as MANIFOLD-EXHAUST, with the aftermarket replacement cross-reference HN3943871. The manifold collects exhaust gases from multiple cylinder ports and directs them into a single outlet pipe. A cracked or warped manifold often causes a loud ticking noise under acceleration and may reduce fuel efficiency. Exhaust leaks near the manifold can also introduce dangerous fumes into the operator compartment if the seal fails. Verify the serial number or application, then call (562) 693-7748. This aftermarket part is a catalog reference for the Hyundai exhaust manifold assembly.
