Willall R35 GTR Oil Air Separator System WR35OAS 

High Performance GTR engine builds need better than factory breathing systems to stop oil coming back into the inlet system. Years of testing has shown this to be the perfect design that not only cleans the oil from the inlet system, it also eliminates and chance of engine bay and cabin oil smells as a lot of other non-sealed systems can deliver.

The breathing container itself is an industrial item that has been proven in big engine applications for over a decade. The internal filter is removeable and washable, and replacement elements are also available. Another neat bonus is that when mounted in the GTR engine bay WR35OAS is out of sight tucking away just under the top radiator hose. The top of the breather system is removeable making visual inspections simple and quick.

To clean and drain the WR35OAS there is a small tap on the bottom that allows the contents of the breather system to be drained out through a tiny hose into a tray for simple disposal.
