Circuit Sports oil pan baffles are engineered for compatibility with NA 1.6/1.8, NB 1.8, and Mazdaspeed Turbo 1.8 engines—making them the only baffle on the market designed to work with the Mazdaspeed platform.

This baffle significantly improves oil retention around the pickup tube during high G-force conditions, helping maintain proper lubrication under demanding driving.

The center section features two Viton flaps that function as one-way valves, allowing oil to return to the sump during acceleration while preventing it from escaping during deceleration.

Note: Installation requires engine removal and oil pan removal from the block. It is recommended to install this during an engine rebuild while the motor is on a stand.

Minor bending is required to secure the four-post center piece (with Viton flaps) to the two outer sections. Please refer to the final image for guidance.
