Mopar diesel exhaust fluid injector hoses are heated to ensure the DEF transferred from the pump to the injector does not freeze during normal vehicle operation, which can consequently illuminate the check engine light and limit the vehicle operating speed. Injector hoses are validated by our in-house team of Mopar engineers ensuring it meets OE requirements.
