Yep, a 3rd vote for MotorWest Performance. We featured their injectors in the video below 4 years ago.
Denso Fuel Injector Replacement Set for 3.4L V6 4Runner Tacoma and Tundra – HP831 (Naturally Aspirated 5VZ-FE only) – MotorWest Performance
I've never heard one complaint about the injectors MotorWest Performance sells. I've met the owner, Martin Diaz, and he's a solid guy who stands behind his products.
