The Cometic Nissan 300ZX 1990 - UP 88mm .045 inch MLS Head Gasket VG30DE/DETT 3L V6 - C4346-045 is a precision-engineered head gasket with a 88mm bore and .045" compressed thickness.
The Cometic Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers that conform to surface irregularities and maintain a positive seal. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.
