Product Information
⚠️ 2026 Model Year Notice: A recent ECU calibration update has lowered the P04DB threshold, which may trigger a check engine light. ECU re-calibration is required to clear this code. Our previous facelift fix does not apply to 2026 calibrations.
Eliminate the P04DB code from installing a SXTH intake on the 2024-2025 Hyundai Elantra N with our new crankcase ventilation hose assembly. This is the only fix on the market that will not affect crankcase pressure!
***This should work for every intake system available. If you still get the Code 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.
