The Subaru OEM Lower Fuel Injector Seal (Part Number: 16395AA050) is a genuine factory rubber seal designed for the fuel injector assembly on select 2015–2021 Subaru WRX models equipped with the FA20DIT 2.0L turbocharged Boxer engine. This lower injector seal creates a secure seal between the fuel injector and the cylinder head, helping maintain proper fuel delivery, combustion efficiency, and engine performance.
Manufactured to Subaru's exact specifications, this seal is engineered to withstand the extreme temperatures, fuel exposure, and pressures found in direct-injection fuel systems. It is highly recommended to replace injector seals whenever fuel injectors are removed during maintenance or engine repairs.
