Stage X Subaru Impreza Oil Catch Tank GC8 - GF8 1992-2000 Right Hand Drive

Fitting a Stage X oil catch tank has several benefits.

On a standard engine, oil vapour from the crankcase and cylinder heads is usually recycled back through the air intake system. This oil-contaminated air is then drawn into the engine, which lowers the octane level of the fuel during combustion and so reduces power. The oil residue also coats the intake hoses, turbo, intercooler and connecting pipework, which slows air flow, reduces cooling ability and causes general wear.

A catch tank vents the excess vapour into a separate tank, where the oil is separated from the air before being returned directly to the sump. This keeps the engine's breathing system clean and free of oil residue, and is especially useful on high-performance or tuned engines, where dense oil vapour can hurt performance.

Unlike universal tanks, Stage X tanks are made specifically for the Impreza, for easy, straightforward fitment and a factory look.

This part is the tank only. It is intended for those who want to use their own oil breather lines and fittings.
