No idea beyond the fact that they are "Bosch-style" and high-impedance. The OEM injectors have some letters on them but no brand markings. FWIW, I have seen a lot of other injectors that could physically fit into a K-motor fuel rail but might not be do-able for various reasons (resistance, etc.)aha,
next question>> see how you do with this one
OEM type-s (and other K injectors)
are they Denso Hi-Z ???
look sort of like Pico style injectors, but dont know if pico-denso is a sort of derivative of the other
