Product Description

The Cometic PRO2023C Complete Engine Gasket Kit is designed to fully reseal the Subaru EJ205 2.0 L Turbo engine in the 2004-2005 Impreza WRX and its related models (Saab 9-2X Aero). It provides both top-end and bottom-end gaskets and seals, including a high-strength MLX (metal laminate) head gasket with .041-inch thickness, front and rear crank seals, intake & exhaust gaskets, and all of the small seals required when disassembling an EJ205. This makes the kit ideal for rebuilds, high mileage overhauls, or performance builds where ensuring no leaks and solid sealing under boost is critical.

When selecting this kit, verify your engine uses EJ205 with the correct bore (standard 93 mm or the 92 mm variant) and that the engine block and head mating surfaces are clean, flat, and prepped properly. Also confirm your build date (2004-2005) since design changes may affect gasket compatibility. Though the kit is confirmed through 2005, compatibility with EJ205 engines outside that production window or with heavily modified blocks should be double-checked. Proper installation torque sequences, gasket sealant (if required), and component alignment are essential for optimal performance and longevity.
