If Michelangelo, Picasso, and the guy who invented a Swiss army knife collectively raised a stepchild, more than likely he or she works for Killer B motorsports. Literally everything they make out of metal hits you hard in the feels because the craftsmanship is sensory overload. 

Their Oil Baffle Windage Tray is no exception. Although the boxer engine sets Subaru apart from most sport compacts, they do have oil sloshing issues with oil going back and forth from head to head under extreme cornering. Here are some advantages of the Killer B Windage Tray:

•    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.

Wicked good. I think.

I honestly don't know how much this helps - but if you're going through the trouble of having your oil pan off, it (and the killer b pickup, of course) is cheap insurance. The part is extremely well made, and fits like a glove.

Wonderfully Made

I bought this along with the oil pickup (mine had a hairline crack I would never have known about!) and it looks so nice it's a shame it's sloshing about it oil now!

Install is easy enough and a better design than the OEM ,so why not?

Much better

If the job of the baffle is to keep splash from the pan back up into the crank, then this will do a much better job of doing so over the OEM. with no moving parts to break over time, and a better design than the OEM, i rate this 5/5 stars. much better and thicker part than the OEM would ever be, and i have a 2012 sti!

  • AnswerQ: The difference?  jkkarkar 3 years ago

    What is the difference between this and the Cosworth Oil Control baffle? Do they do something entirely different with the oil? Thanks guys

    • A: The Cosworth unit also features trap doors to prevent oil movement, where this unit is a upgrade for the factory baffle with out any trap doors/flaps.

      Kirill C. 3 years ago

    • A: Our baffle is not a plate that goes between pan and block making for a much easier leak free install. It replaces the OEM baffle. There are no moving parts to sag open over time or malfunction, and oil will not travel across our baffle under severe cornering loads.
