Perhaps one of the most cost effective and vital modifications for the EJ Series engine is to provide additional baffling to the oil system.
Subaru is one of few manufacturers who choose to use a horizontally opposed engine to provide improved balance and also achieve a lower centre of gravity.
The downside of this design is that oil (contained in the sump), has a tendency to travel over to the cylinder heads when under significant centrifugal force from hard or consistently long cornering.
The standard sump oil pan contains a limited baffle system however it is usually not deemed anywhere near adequate enough for vehicles used on track, or heavily modified cars producing a greater bhp.
The Fuji Racing Oil baffle plate kit provides a cost effective solution in which to combat this problem, by helping to keep oil contained in the oil sump pan where it belongs!
