Throttle Body

The throttle body is a key component in every combustion engine, regulating airflow into the intake manifold and directly affecting horsepower, torque, and throttle response. EVIL ENERGY provides a complete line of Throttle Bodies, available in both Electronic Throttle Body and Mechanical Throttle Body designs. With multiple inlet sizes—85mm, 90mm, 92mm, and 102mm—these products are ideal for performance upgrades and reliable replacements.

EVIL ENERGY Electronic Throttle Body

The EVIL ENERGY Electronic Throttle Body uses an advanced motor-driven system controlled by the ECU. This ensures precise throttle response, smoother acceleration, and improved fuel efficiency. It is the perfect upgrade for modern vehicles where electronic control is required.

  • Inlet diameters: 85mm, 90mm, 92mm, 102mm
  • Designed for high airflow and stable performance
  • Ideal for drivers who want sharper throttle control and improved engine response

EVIL ENERGY Mechanical Throttle Body

The EVIL ENERGY Mechanical Throttle Body features a traditional cable-driven design, offering a direct connection between the accelerator pedal and the throttle plate. This system delivers immediate feedback and a pure driving feel, making it a popular choice for classic cars and specific custom builds.

  • Immediate throttle feedback
  • Reliable and durable mechanical design
  • Available in 92mm and 102mm options

Car Throttle Body Maintenance & Cleaning

Over time, any car throttle body can accumulate carbon deposits and oil residue, which may cause rough idling, reduced fuel economy, or power loss. Performing a cleaned throttle body service helps restore optimal airflow and keeps the engine running smoothly. Regular inspection and cleaning are recommended for both electronic and mechanical throttle bodies.

What is Throttle Body?

A throttle body is a key component in every combustion engine vehicle. Its main job is to regulate the airflow into your car’s engine, directly affecting the air-fuel mixture and acceleration.

When you press the gas pedal, the throttle body opens to let more air into the intake manifold, prompting the injectors to add more fuel, and your car speeds up.

⚠️ Note: If the throttle body becomes dirty or faulty, you may experience poor performance, rough idling, or delayed throttle response.

Cleaning or replacing it with a high-quality aftermarket part like the EVIL ENERGY Throttle Body can restore smooth performance.

Throttle Body Diameter

The throttle body diameter (e.g., 70mm, 80mm, 92mm, 102mm) directly determines the amount of air entering the engine. Smaller throttle bodies (70–80mm) are more suitable for daily driving, providing moderate airflow and smoother throttle response. Larger throttle bodies (92mm and above) allow greater airflow, improving intake efficiency at higher RPMs, and are preferred by modification enthusiasts to enhance horsepower and torque performance.

How Does a Throttle Body Work?

A throttle body is a key component in every combustion engine vehicle. Its main job is to regulate the airflow into your car’s engine, directly affecting the air-fuel mixture and acceleration.

Inside the throttle body, there’s a butterfly valve that rotates to control airflow:

  • Mechanical Throttle Body: The gas pedal is connected via a cable that physically opens the valve.
  • Electronic Throttle Body (ETB): Sensors and the ECU (‘drive by wire’) control the valve electronically, allowing more precise adjustments for better fuel efficiency and emissions control.

Location

  • Carbureted Engines: Built into the carburetor, operated by cable and vacuum.
  • Fuel-Injected Engines: Positioned between the air filter and intake manifold, controlled either mechanically (cable) or electronically (by wire).

FAQs about Throttle Body

What does a throttle body do?

A throttle body controls the amount of air entering the engine. By regulating airflow, it determines how much fuel is mixed for combustion, directly affecting power, acceleration, and efficiency. Both EVIL ENERGY Electronic Throttle Body and EVIL ENERGY Mechanical Throttle Body options are designed to provide smooth and reliable airflow for different vehicle setups.

When a car throttle body begins to fail, common symptoms include rough idling, reduced fuel economy, poor acceleration, or even the engine stalling. In severe cases, the check engine light may appear. Regular maintenance or a cleaned throttle body service can help prevent these issues.

The cost of fixing or replacing a throttle body depends on the type (electronic vs. mechanical) and the vehicle model. Generally, an EVIL ENERGY Throttle Body offers a cost-effective alternative to expensive OEM parts, giving you both performance and durability without breaking the bank.

Replacing a car throttle body usually takes between 1 to 3 hours, depending on the vehicle and accessibility. Both the EVIL ENERGY Electronic Throttle Body and EVIL ENERGY Mechanical Throttle Body are designed for easier installation, making the process more straightforward for professionals and DIY enthusiasts.

Yes. Installing a new EVIL ENERGY Throttle Body—whether electronic or mechanical—can improve throttle response, restore lost power, and enhance overall drivability. A properly sized throttle body (such as 85mm, 90mm, 92mm, or 102mm) allows more airflow, which can translate into noticeable performance gains when combined with other upgrades.
