The Cometic Honda/Acura DOHC 82mm B18A/B .030 inch MLS Head Gasket nonVTEC - C4173-030 is a precision-engineered head gasket with a 82mm bore and .030" compressed thickness.

The Cometic Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short.
