This CNC billet machined adapter plate will allow you to install a larger throttle valve on your 2UZ-FE V8 engine. It fits the 2UZ-FE 4.7L engines found in the Tundra, Sequoia, LandCruiser, 4Runner Lexus GX470, and LX470 Model years 2005-2009. Does not fit earlier 4.7L engines. This will allow you to adapt the much larger throttle from the Lexus RCF to your engine for better airflow and less throttle restriction.
- The adapter plate uses an O-ring for proper sealing
- May have to use a larger silicone coupler to adapt the larger throttle valve to the intake system
- The RCF Throttle Valve is not included. Use Lexus part number 22030-38050.

Very satisfied. Low speeds are very smooth. Drives perfectly smooth sitting in traffic. It pulls very strong at part throttle and WOT . It will need some tuning to compensate for increased air flow at WOT. Driving around town is as smooth or aggressive as your right foot wants. It’s easy to drive slow and it’s easy to drive fast. There’s a ton of throttle response above 20000 RPMs. I’m also using the aFe air box with it. So far, it has a massive power increase. Absolutely night and day.
