Questions and Answers

Why is it crucial to distinguish between MPI and GDI fuel injectors for the Theta II engine?
MPI (Multi-Port Injection) injectors operate at lower pressures into the intake manifold, whereas GDI (Gasoline Direct Injection) injectors operate at extremely high pressures directly into the combustion chamber. They are physically and electrically incompatible.
Will this injector work in my Sonata Hybrid?
Yes, the 35310-2G300 is designed for the specific flow-rate and duty-cycle requirements of the Theta II MPI architecture found in both standard and hybrid powertrains of that generation.
How can I confirm if my vehicle uses MPI or GDI injection?
