Killer B Motorsport Baffle. 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. 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.


  • 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!

Looks nice

I'm not sure exactly what benefits this will provide over stock, but it is quite a bit smaller and doesn't hang as far into the oil pan. I installed it at the same time as the killer b pickup, so it seemed like a good upgrade.


Thank you for your 5 Star Review of the Killer B Motorsport Oil Baffle Windage Tray! This tray helps reduce the sloshing around of oil in your pan which creates a foamy mess. It also keeps the oil where it needs to be when in needs to be there and prevents oil interference under hard driving! It works perfectly in sync with the Killer B Pickup that you installed as well!

Excellent fitment on my Baja fits better than OEM

Trey fits much better than OEM and is not paper thin like oem very well made thick and robust and will last for many years to come Killer B should be the standard on all Subaru engines when it come to the oiling system


Thank you for the 5 Stars! If only Killer B Motorsports parts came stock! The Oil Baffle Tray is a huge upgrade from the flimsy OEM design keeping oil where its supposed to be! The quality alone provides plenty of corrosion protection ensuring your motor runs clean!


Easiest Install

This mod is a no brainer. If you have the oil pan off your car for any reason, definitely upgrade your oil capacity, pickup and this baffle.


Thank you for the 5 Star Review! The Killer B Windage Tray is as you say a no brainer! This goes perfectly with the Killer B Oil Pickup as well! Definitely some of the best and most beneficial upgrades you can do to preserve your motor!
