SXTH Element Elantra N Intake CEL (P04DB) Fix Kit

Eliminate the P04DB Check Engine Light from installing a SXTH intake on the 2024-2025 Hyundai Elantra N with our new crankcase ventilation hose assembly.

This kit is included in all SXTH Intake systems starting 2/1/2026. If you already have a SXTH Intake, and you have gotten a CEL, please email us so we can send you this for free!

***This should work for every intake system available. If you still get the CEL after install, please contact us.

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.
