Wilwood Throttle Body Upgrade: Step-by-step Installation and Performance Results

The Wilwood throttle body upgrade is a popular modification for car enthusiasts looking to enhance their vehicle’s performance. This article provides a comprehensive step-by-step guide on how to install the Wilwood throttle body, along with the performance results you can expect after the upgrade.

What is a Throttle Body?

A throttle body is a critical component of an engine’s air intake system. It controls the amount of air that enters the engine, which in turn affects engine performance, efficiency, and responsiveness. Upgrading to a high-performance throttle body like the one from Wilwood can lead to significant improvements in these areas.

Benefits of Upgrading to a Wilwood Throttle Body

  • Improved Airflow: The larger diameter of the Wilwood throttle body allows for increased airflow, which can lead to better engine performance.
  • Enhanced Throttle Response: A high-performance throttle body provides quicker response times, making your vehicle feel more responsive during acceleration.
  • Increased Horsepower: Many users report noticeable gains in horsepower after upgrading to a Wilwood throttle body.
  • Better Fuel Efficiency: Improved airflow can also lead to better fuel efficiency, depending on your driving habits.

Tools and Materials Needed

  • Wilwood throttle body kit
  • Socket wrench set
  • Screwdrivers (flathead and Phillips)
  • Torque wrench
  • Gasket scraper
  • New intake manifold gasket
  • Shop towels
  • Safety glasses

Step-by-Step Installation Guide

Step 1: Prepare Your Vehicle

Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Disconnect the negative battery terminal to prevent any electrical issues during the installation process.

Step 2: Remove the Existing Throttle Body

Begin by removing the air intake duct connected to the throttle body. Use a screwdriver to loosen the clamps and carefully detach the duct. Next, disconnect any electrical connectors and vacuum lines attached to the throttle body.

Using a socket wrench, remove the bolts securing the throttle body to the intake manifold. Carefully lift the throttle body away from the manifold, taking care not to damage any surrounding components.

Step 3: Clean the Mounting Surface

Once the old throttle body is removed, use a gasket scraper to clean the mounting surface on the intake manifold. Ensure that all remnants of the old gasket are removed to create a proper seal for the new throttle body.

Step 4: Install the Wilwood Throttle Body

Place the new intake manifold gasket onto the cleaned surface. Align the Wilwood throttle body with the bolt holes and gently lower it onto the gasket. Secure the throttle body with the provided bolts, tightening them to the manufacturer’s specifications using a torque wrench.

Step 5: Reconnect All Components

Reconnect any electrical connectors and vacuum lines that were disconnected during the removal process. Reattach the air intake duct, ensuring all clamps are tightened securely.

Step 6: Reconnect the Battery and Test

Reconnect the negative battery terminal and start the engine. Allow it to idle for a few minutes while checking for any leaks around the throttle body. If everything looks good, take the vehicle for a test drive to experience the performance improvements.

Performance Results

After installing the Wilwood throttle body, many users report significant improvements in their vehicle’s performance. Here are some common results:

  • Increased Acceleration: Users often note a more responsive throttle and quicker acceleration from a standstill.
  • Higher Top Speed: The improved airflow can contribute to higher top speeds, especially in performance-oriented vehicles.
  • Enhanced Engine Sound: Many enthusiasts appreciate the more aggressive sound of the engine with the upgraded throttle body.
  • Better Overall Driving Experience: The combination of improved throttle response and power delivery makes for a more enjoyable driving experience.

Conclusion

The Wilwood throttle body upgrade is a worthwhile investment for those looking to enhance their vehicle’s performance. By following the step-by-step installation guide, you can successfully upgrade your throttle body and enjoy the benefits of increased horsepower, improved throttle response, and an overall better driving experience.

Always remember to consult your vehicle’s manual and follow safety precautions during installation. Happy driving!
