Frequently Asked Questions (FAQ)

Q: Do I need to reprogram my car’s computer after installing a new throttle body?

A: Often, yes. Many modern vehicles require a throttle body relearn procedure after installation. Consult your vehicle’s owner’s manual or a professional mechanic for specific instructions.

Q: What is the difference between an 80mm and a 90mm throttle body?

A: The difference lies in the bore diameter, which determines the amount of airflow. A 90mm throttle body generally allows for greater airflow, potentially leading to improved performance, especially at higher RPMs. However, this increase can necessitate additional tuning of the car’s computer and could even potentially cause some issues if you don’t.

Q: Will installing a larger throttle body void my warranty?

Q: How difficult is it to install a new throttle body?

A: The difficulty varies depending on the vehicle and the individual’s mechanical skills. While some consider it a relatively straightforward DIY job, others might prefer to have a professional mechanic handle the installation.

Q: What other modifications should I consider alongside a new throttle body?

A: For optimal performance gains, consider a cold air intake, performance exhaust system, and possibly engine tuning.

Q: Can I install a throttle body on my 5.7L Hemi myself, or do I need a mechanic?

A: You can potentially install a throttle body yourself if you’re comfortable working on vehicles and have the necessary tools. However, if you are not comfortable doing this, it is always best to have a mechanic do it. Improper installation can lead to problems.
