This is a Toyota OEM 2jzgte front main seal. We recommend replacing this seal whenever doing a timing belt replacement or JZ engine swap. This seal is somewhat more labor intensive to replace as it requires removing the timing belt and crank sprocket, so we only use Toyota OEM front main seals because they are the best quality. This front main seal will work with all 2jz/1jz engines including non-turbo and VVT-i variants. Be weary of cheaper, inferior quality seals that are sometimes marketed as OEM, as they have been known to leak!
