The Hyperflow Racing Oil Sump (oil pan), designed for the WRX / STi was originally developed in conjunction with leading UK and Australian WRX Racing specialists. Our objective to was to provide an affordable top-end racing sump for Race, Rally, drag, drift and hard road drivers.

The Sump provides a number of benefits when compared with a standard unit.
1.An all Alloy “winged sump” reduced surge, increased capacity and greater cooling.
2.Doubles Sump capacity on the 2.5L engine from 3 to 6 L and increases capacity on the 2.0L engine from 4.3 to 6 L
3.A finned Billet machined base plate to significantly increase cooling and reduce the chance of puncturing
4.Internal baffling to dramatically reduce oil surge
5.Precision CNC machined billet mounting flange – perfect fit
6.From September 2007, the Sump now incorporates a full O –ring seal on the base flange and high temperature O-ring
7.Ball Burnished polished finish
