Killer B Motorsport Baffle for EJ20/EJ25 WRX and STi features a closed rear section to prevent oil from sloshing into the crank under hard acceleration and aggressive shifts.
Vehicle Fitment:
2002-2014 Subaru WRX
2004-2021 Subaru STi
• EJ20/EJ25
More Info:
Block contoured profile to minimize oil returning from the heads interfering with the crank. Directional louvers prevent oil in the pan from splash/sloshing into the crank. Low profile design to control windage and strip oil from the crank immediately to reduce oil “roping” on the crank. Improved oil entry to the pan/pickup to help prevent oil starvation. Made from stainless steel for long life, durability and corrosion resistance.
- Uses OEM baffle mounting locations
- Not a sandwich between pan & block design that is difficult to install and more prone to leak.
- No rubber parts that can sag and stay open after repeated heat cycling.
- Not Holy Cow expensive!
So what’s all this mean? It means more power due to the reduction in oil interfering with the rotation of the crank and allowing it to spin more freely. Unless it’s in the bearings, anytime oil comes in contact with the cranks or connecting rods it robs power. Reduction of oil splashing and beating off crank & connecting rods will also lower oil temperatures.
