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

Fitting an RCM Oil Catch tank kit offers many 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 ingested by the engine, which lowers the octane level of the fuel during the combustion process and therefore reduces power. In addition, this oil residue also coats intake hoses, turbo, intercooler, and connecting pipe work, which in turn slows air flow, reduces cooling abilities, and causes general wear and tear. 

Fitting a catch tank kit enables you to vent all excess vapours directly into a separate tank where the oil is then separated from the air before being returned directly back into the sump oil pan. This ensures your engine's breathing system is kept clean and free of oil residue to maximize its efficiency and can be especially useful in high performance or tuned applications where dense oil vapour can have a detrimental effect on performance.

Further advantages of an RCM catch tank kit are that aside from receiving all the corresponding parts required for a complete installation, we also supply an oil drain hose which connects between the catch tank and the sump, meaning your precious oil is never left filling up in your tank and instead is returned back to the engine where it belongs.

Unlike universal tanks, all RCM tanks are manufactured specifically for the Impreza, which guarantees easy, straightforward fitment for that factory appearance. 

This part consists of the tank only and is designed for users who wish to use their own oil breather lines and fittings.
