Review on 🏎️ Skunk2 Racing 309-05-1030 Alpha Series Silver 66mm Throttle Body for Honda B, D, H, F-Series Engines: Boost Your Engine's Performance by Justin Early

TPS sensor does not fit properly on shaft and throttle plate is out of spec Cannot calibrate from 0.5V to 4.5V, you must resolve this issue before Installation or the idle speed rises and falls rapidly, the voltage readings must be accurate, the engine runs lean after the installation failed the emissions test (Honda tuning required), leave the throttle screw alone, do not try to adjust this (problem with stuck gas). , Skunk2 does not use shaft seal, only one bearing, do not use for turbo, increase shaft leakage with a throttle cable (do a leak test), I have two of them and both have the same problem, use Edelbrock 4791 instead.
