* Replacement Silicon Washers for GReddy Baffle Plates - 13515901-WS --- - --- 13515902 (BLUE) > SUPERSEDED TO GOLD FINISH 13515903 Engine: FA24 - ZN8 GR86 / ZD8 BRZ Aluminum baffle plate with a shark duct that balances engine oil to prevent oil pick up problems.Smooth oil directing to oil pick up. Increase stability for oil pressure.Ideal for high G-loads. Both cornering and acel / decel situations. ●The FA20/FA24 engine has a structure in which a large amount of engine oil accumulated in the oil pan flows into the front chain cover due to intense braking G when driving on a circuit. The oil pressure will drop, and in the worst case, the engine may blow.●The GReddy oil pan baffle plate prevents the engine oil from becoming uneven during acceleration/deceleration and cornering. Designed to go back.compatible for N/A or GReddy turbo applications.Stainless-steel - anodized clear/gold, with GReddy logo. --- - --- 13515901 (BLUE) > SUPERSEDED TO GOLD FINISH 13515904 Engine: FA20 - ZN6 FRS 86 / ZC6 BRZ Aluminum baffle plate with a shark duct that balances engine oil to prevent oil pick up problems.Smooth oil directing to oil pick up.
