Circuit running and hard driving cause oil to lean to one side inside the oil pan.

In some cases, during full-throttle driving or when experiencing lateral G-forces while driving, enough oil may not return to the oil pan, leading to insufficient oil circulation throughout the engine. To prevent this from happening, it is necessary to collect the oil to ensure that the absolute amount of oil circulating throughout the engine is sufficient.

That's where the oil pan baffle plate comes in. It effectively collects the oil inside the engine and promotes engine protection by circulating it from the oil pump to the pistons and bearings. This allows for worry-free full-throttle driving.
