HN3991085: A worn valve spring can cause incomplete valve closure, leading to reduced compression and potential misfiring. This aftermarket replacement part references Hyundai as the OE maker and cross-references part number HN3991085. The spring is a coiled mechanical component that returns the valve to its seated position after each opening cycle. Over time, fatigue or heat exposure may weaken the spring, allowing valve float at higher operating speeds. A failed spring can result in a dropped valve, causing significant internal damage. Verify the serial number or application, then call (562) 693-7748.
