The Killer B Motorsports oil baffle offers the following features and advantages compared to the OEM piece:

• Closed rear section to prevent oil from sloshing into the crank under hard acceleration and aggressive shifts.
• 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.

Benefits of the Killer B baffle over other aftermarket baffles:

• 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 the crank and connection rods will also lower oil temperatures. Consider upgrading to the and/or the , since your oil pan is going to be off anyway...
