Elantra N Intake CEL (P04DB) Fix Kit

Reduce or Eliminate the P04DB Check Engine Light from installing an aftermarket intake on the

2024-2025 Hyundai Elantra N with our new crankcase ventilation hose assembly.

This hose is a direct replacement for the OEM Crankcase Ventilation (CV) hose that connects the valve cover to your intake system.

The hose works to regulate the crankcase pressure in the hose/valve cover within sensor limits when an aftermarket intake is installed.
