Reliable Performance for KA24DE Engines

The KA24DE is a workhorse engine, and the Cometic 89mm Bore .040 inch MLS Head Gasket is designed to keep it running strong. Whether you are performing a rebuild or upgrading for forced induction, this gasket provides the sealing power required to handle increased cylinder pressures. The .040 inch thickness is a popular choice for those looking to maintain or slightly bump compression for better throttle response and power.

Why Choose Cometic MLS?

  • Bore Diameter: 89mm perfectly matched for standard and slightly over-bored KA24DE engines.
  • Thickness: .040 inch compressed thickness for precise compression tuning.
  • Construction: High-grade Multi-Layer Steel (MLS) for maximum durability.
  • Reliability: Resists blowout and coolant leaks under high-performance conditions.
  • Ease of Install: No re-torquing required after installation.

Cometic's MLS gaskets are designed to handle the unique thermal expansion characteristics of the Nissan KA24DE engine. The outer layers are coated with a high-temperature polymer to ensure a perfect seal against the block and cylinder head, even if the surfaces aren't perfectly smooth. This is the ultimate upgrade for any 240SX owner looking to ensure their engine stays sealed under load. Trust your build to the industry leader in performance gaskets.
