I did a boost leak test on my car and hear a slight leaking noise from the injector area as well as the throttle body. its very minor. i ordered the WORKS Aperture High Pressure Shaft Seals. now i need to order the seals for the injector. my question is which seals do i need (i am assuming oem seals work with my pte 680's)

i have found these, do i need both?
