Application and ordering
RCM lists this 2002MY+ EJ20/EJ22/EJ25 kit for Subaru Impreza WRX and STI models registered from November 2002 onwards. Confirm the engine and timing arrangement on your car before ordering, especially if the engine has been replaced or modified.
This listing is for the timing belt kit. A water pump is not included. Both options include a complete kit; the motorsport choice replaces the standard tensioner rather than adding a second tensioner.
