Ported Throttle Bodies

Unlocking More Power and Response

When it comes to getting more out of your vehicle without diving into major engine modifications, a ported throttle body is one of the smartest and most effective upgrades you can make. At Tracy Lewis Performance, the collection of ported throttle bodies is engineered to deliver noticeable improvements in throttle response, low-end torque, and horsepower—all while maintaining OEM reliability and drivability.

Why Upgrade Your Throttle Body?

The throttle body is the gateway to your engine’s intake system. It regulates airflow into the combustion chambers, directly influencing performance and responsiveness. Factory throttle bodies are designed with efficiency and cost in mind, not necessarily maximum performance. By precision-porting and refining these components, Tracy Lewis Performance improves airflow, reducing restrictions and optimizing efficiency.

The result? Sharper throttle response, stronger acceleration, and measurable power gains.

Proven Performance Gains

Customers who install a Tracy Lewis Performance ported throttle body consistently report:

• Increased Throttle Response: Smoother, quicker reaction when you step on the gas, making the vehicle feel more alive and connected.

• Gains in Low-End Torque: Stronger pull off the line and improved drivability in everyday conditions.

• 4–12 RWHP Increases: Depending on the application, dyno-tested results show rear-wheel horsepower gains in this range, offering real-world performance improvements you can feel.

These benefits make ported throttle bodies one of the most cost-effective ways to wake up your engine.

Applications and Options

The Tracy Lewis Performance collection includes a wide variety of ported throttle bodies tailored for different GM engines and platforms. Whether you’re running a naturally aspirated setup or a supercharged application, there’s an option designed to optimize your airflow.

Each unit is carefully CNC-machined and hand-finished to ensure precision and consistency. Unlike generic solutions, these throttle bodies are specific to your engine, ensuring proper fitment and maximized results.

Everyday Drivability Meets Performance

One of the biggest advantages of a ported throttle body upgrade is that it doesn’t compromise drivability. You’ll notice crisper throttle inputs during spirited driving, but you’ll also enjoy smoother operation during normal commutes. It’s the perfect balance of daily comfort and performance fun.

And because these upgrades maintain compatibility with OEM electronics and hardware, installation is straightforward and reversible. There’s no need for extensive modifications or tuning—though pairing with other upgrades can further maximize results.
