Subaru (EJ) – Fuji Racing Oil Sump Baffle Plate & Windage Tray

Description

Take Back Control.

One of the most cost-effective and essential modifications for enhancing the performance of the EJ Series engine is the addition of improved baffling to its oil system. Subaru is unique among automotive manufacturers, as it employs a horizontally opposed engine design, which provides notable benefits like enhanced balance and a lower center of gravity, factors that contribute to better vehicle handling and stability.

However, this specialized engine layout has its challenges. Under conditions of high centrifugal force—typically experienced during aggressive driving maneuvers, such as hard cornering or sustained turns—oil contained in the sump tends to shift toward the cylinder heads. This displacement can lead to inadequate lubrication for critical engine components, resulting in potential performance issues or even engine damage.

The standard oil pan features a basic baffle system, but this setup is often inadequate for high-performance vehicles that are frequently used on racetracks or for heavily modified cars that produce significantly increased brake horsepower (bhp). Without proper oil containment, these vehicles might face starvation issues, impacting engine reliability and efficiency.

To address this pressing concern, the Fuji Racing Oil baffle plate kit presents an effective solution. This kit is designed to enhance oil management by incorporating a sophisticated baffle design that minimizes oil slosh and helps ensure that the oil remains where it is most needed—within the sump. By keeping the oil securely contained during intense driving conditions, this modification can help maintain optimal lubrication and performance, making it a smart investment for serious enthusiasts looking to maximize their engine’s potential.

Protect The Lifeblood of your Engine.

Available to purchase as a complete kit or as individual components, we offer a sump oil baffle plate which locates between the face of the engine block and sump, and additionally a replacement windage tray for the crankshaft.

The FUJI oil baffle plate has been specifically designed to let oil flow from the engine down into the sump pan. Each hole / slotted louvre has been strategically placed to ensure oil can flow quickly and efficiently back down towards the oil pick up pipe.

Likewise should the oil be forced to the top of the sump (due to cornering forces) the escape path is now far harder to overcome with the baffle in place.

Our FUJI windage tray has been designed to work in harmony with the sump baffle, directing oil toward the centre of the plate for fast and easy routing of the engine oil.
