Reliable Material: Made of high quality polyamide materials and durable rubber O-ring. Build to factory original quality OE specifications to ensure a proper fit. Make sure you use it for a long time.
Replace Gas Cap: Most gas caps are sealed by turning them until you hear a click. An old, loose, cracked or otherwise faulty gas cap may cause your check engine light CEL to turn on. If your check engine light is on, or if you smell gasoline or diesel vapors around or near the filler cap and your car is not smoking or making unusual noises, take a minute to check the gas cap.
