The 044 is neither Cossie or S2. It won't directly fit without an adaptor which can be purchased from A1 Rallye Sport.

However it is totally unnessesary unless you want over 400bhp in which case you will need the 044. The 941 will suffice up to that limit.

The 044 will flow 200l/h at 5 bar or 3.33 recouring per minute at 5 bar.
