What size throttle body is this?
This throttle body features a 102 mm bore size, which can affect airflow capacity and overall engine performance.


Do I need to verify flange compatibility before installation?
Yes, flange pattern and sealing surface compatibility should always be confirmed before installation.


What type of throttle body is this?
This is a performance throttle body designed for efi applications.


Will this throttle body help improve throttle response?
Yes, a properly matched performance throttle body can help improve airflow response and throttle feel compared to a more restrictive stock-style unit.


Do I need to match the throttle actuation style to my setup?
Yes, throttle actuation style must match the intended control setup for proper operation and installation.


Do I need to verify sensor compatibility before installation?
Yes, throttle body sensor and connector compatibility should always be confirmed against your engine management system.


Does this throttle body support common EFI engine management setups?

Do I need additional parts for installation?
Depending on your setup, you may need a gasket, hardware, adapters, or tuning support during installation.


Is this throttle body a good option for higher-horsepower builds?
Yes, larger-bore throttle bodies are commonly used on higher-output combinations that need increased airflow capacity.


Will this throttle body help support added airflow demand?
Yes, a properly matched performance throttle body can help support engines with intake, camshaft, cylinder head, or forced induction upgrades that demand more airflow.


Do I need tuning after installing a throttle body?
Depending on the application and the size change, tuning may be recommended to get the best drivability and performance results.


Does the natural finish affect performance?
No, the natural finish does not change throttle body performance—it provides a raw functional appearance.
