Air Intake Resonator

An intake resonator is on the engine's incoming-air side; an exhaust resonator is part of the exhaust path. Both can influence sound, but they are different components in different systems.

The resonator and air filter perform different jobs. A resonator listing does not by itself establish that a filter is included; check the selected package if the filter also needs replacement.

A split in an intake duct can contribute to a warning on some systems. The effect of damage depends on where the opening is located and how the engine measures air; inspect the complete intake and diagnose any stored fault before replacing a resonator.

Replacing a damaged resonator restores the intended intake configuration. Any change in performance depends on the original condition and engine; a replacement is not a guaranteed horsepower upgrade.

The chamber and its connections are designed for a particular intake layout. For example, one listed Elantra duct fits specified 1.4 L and 2.0 L engines but excludes the 1.6 L; another resonator is identified as lower. Match the exact application and position.
