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 ported throttle bodies are 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.

What Customers Report

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: Depending on the application, our dyno testing and customer results have shown rear-wheel horsepower gains in this range.

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

Applications and Options

Four ported throttle bodies cover GM and Ford: the GM ported throttle body for the LLT, LFX and LGX 3.6 V6, the GM 80mm for the LFX and LGX, the Gen V LT1 unit for the Camaro SS and Corvette, and the Ford EcoBoost unit for the 2.7 and 3.5. Whether you are running a naturally aspirated setup or a supercharged application, there is 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 does not compromise drivability. You will notice crisper throttle inputs during spirited driving, but you will also enjoy smoother operation during normal commutes. It is the perfect balance of daily comfort and performance fun.

The stock-bore GM and Ford units bolt on with no other changes. The GM 80mm flows more air than the factory bore and requires a tune, which we can supply. Pairing any of them with a ported intake manifold or the RX Insolator spacer compounds the gains.

Why Tracy Lewis Performance?

Tracy Lewis Performance has built a reputation for precision, reliability, and results. Every ported throttle body is:

• Designed for Long-Term Reliability, ensuring OEM-level durability.

This combination of craftsmanship and proven performance sets them apart from off-the-shelf alternatives.

The Bottom Line

For enthusiasts looking to improve throttle response and low-end torque and add measurable horsepower without major modifications, a ported throttle body from Tracy Lewis Performance is a clear choice. With customer and dyno results of 4-12 RWHP depending on the application, these upgrades deliver results you can feel every time you drive. Not sure what a ported throttle body does?
