Radium Engineering Air Assist Injector Seats - Toyota 2JZ-GE VVT-i / 1UZ-FE VVT-i / 3UZ-FE
These Radium Engineering air assist injector seats (SKU 20-0516 single, 20-0516-06 set of six) convert Toyota intake manifolds built for air-assist injectors to take standard top feed injectors. They are the same machined aluminium seats Radium uses in its own fuel rails, and each one presses into the manifold injector port with no modification.
Radium lists this seat for the Toyota 2JZ-GE VVT-i, 1UZ-FE VVT-i and 3UZ-FE. The included FKM O-ring seals each seat in the machined injector counterbore to stop vacuum and boost leaks, and the bore suits a common 14mm lower injector O-ring. Choose a single seat or a set of six from the variant selector.
Note: Not for the 1JZ-GTE or 2JZ-GTE; those engines use Radium's 20-0216 Toyota injector seat. One seat is needed per injector, injectors are sold separately, and Radium advises measuring your lower injector O-ring before ordering. Installation by a professional is recommended.
