Cylinder Head Gasket

The Honda OEM 12251-PLC-004 is a genuine, direct replacement cylinder head gasket designed for specific Honda Civic applications. This gasket, also identified by other names such as Engine Cylinder Head Gasket or Gasket Cylinder HD, is manufactured by reputable suppliers like Nippon and Ishino. This specific head gasket is engineered for use in Honda Civic models with 1.7L engines, particularly those featuring VTEC-E technology. It is also suitable for applications involving 1.6L and 1.7L SOHC engines. The part number 12251-PLC-004 serves as an updated replacement for the previous part number 12251plc003. While some sources indicate a fitment for 2001-2005 Honda Civic models, other information suggests this part may not fit all configurations. For instance, it is explicitly stated that this part does NOT fit a 2011 Honda Civic Si, despite some listings potentially suggesting otherwise. Buyers are strongly advised to verify fitment for their specific vehicle, potentially by providing a VIN, to ensure compatibility. The product is also subject to California Proposition 65 warning regarding cancer and reproductive harm.
