Product Description

The Cometic PRO2014B is a StreetPro Bottom End Gasket Kit built specifically for 1991-1998 Nissan 240SX models equipped with the KA24DE 2.4L DOHC engine, covering both the S13 and S14 chassis. It includes every lower engine gasket and seal needed for a complete bottom end rebuild - from the oil pan to the timing cover - eliminating the need to source individual components separately.

Each gasket uses a material specifically chosen for its application, whether that's MLS for critical metal-to-metal sealing, AFM for machined cover surfaces, or Armor Clad where heat resistance is paramount. Pair this kit with the Cometic PRO2014T top end kit for a full engine rebuild with performance-grade sealing throughout.
