When it comes to LS engine performance, air intake is the unsung hero. Your engine can only make as much power as the air it can ingest, and that's where most stock throttle bodies fall short. They're designed for fuel economy, not maximum performance, leaving significant horsepower on the table.
Holley completely reimagined the throttle body with one goal in mind: delivering unrestricted airflow to your LS engine. Their new 105mm bore design represents the largest opening available in the aftermarket, ensuring your engine can breathe freely at every RPM range. What makes this throttle body truly special is how it blends massive flow capacity with daily drivability.
Unlike some competitors that sacrifice driveability for peak flow numbers, Holley incorporated sophisticated low RPM tapers that maintain excellent throttle response while you're cruising around town. When you're at wide-open throttle, that's when the 105mm bore truly shines, delivering unrestricted air volume that your engine craves for maximum power production.
This throttle body isn't just another bolt-on part—it's a critical component in unlocking your LS engine's true potential. Whether you're building a weekend warrior for the track or upgrading your daily driver for better throttle response, the Holley 105mm EFI throttle body delivers the kind of performance that enthusiasts demand.
Bolt-on installation means you don't need to be a professional mechanic to see the benefits. The throttle body fits most LS applications and includes all necessary hardware for a straightforward upgrade. Once installed, you'll immediately notice the difference in how your engine responds to throttle input.
For LS engine owners who refuse to compromise between performance and drivability, the Holley 105mm EFI throttle body represents the perfect balance of maximum airflow and everyday usability. It's the kind of upgrade you can feel from the moment you press the accelerator.
