Granatelli Motor Sports MEGAZILLA Black Billet LS Intake Manifold – Twin 103mm Inlets
```When maximum airflow is the goal, the Granatelli Motor Sports MEGAZILLA Twin 103mm LS Intake Manifold delivers the capacity serious high-horsepower combinations demand. Machined from premium billet aluminum, the MEGAZILLA is engineered for extreme LS street, drag racing and competition applications where strength, airflow and consistency are critical.
Featuring two massive 103mm throttle-body inlets, a large high-flow plenum and optimized runner layout, the MEGAZILLA is designed to move an exceptional volume of air while supporting strong cylinder filling and mid-to-high RPM horsepower. It is an excellent choice for extreme naturally aspirated engines as well as high-boost turbocharged and supercharged LS builds.
```MEGAZILLA Airflow: This manifold uses TWIN 103mm throttle-body inlets. This is not a single-inlet ZILLA manifold. It is designed for extreme high-airflow LS applications.
Twin 103mm Inlets for Extreme Airflow
```Two 103mm throttle-body openings give the MEGAZILLA enormous airflow potential for LS combinations that have exceeded the practical limits of conventional single-throttle-body intake systems. The dual-inlet configuration is designed to feed the large plenum efficiently and support the airflow demands of large-displacement, high-RPM and heavily boosted engines.

Designed for High-Horsepower LS Engines
```As LS engines increase in displacement, RPM capability and boost pressure, airflow demand rises dramatically. Eventually, a conventional single throttle body and smaller plenum can become a significant restriction.
The MEGAZILLA is engineered specifically for these serious combinations. Its twin-inlet configuration feeds a large-volume plenum designed to provide the airflow capacity needed by engines operating well beyond factory power levels.
```Built for Boost
```High-boost turbocharged and supercharged engines place tremendous demand on an intake manifold. Increased airflow, pressure and engine speed require a manifold with both exceptional flow capability and structural strength.
The MEGAZILLA's billet aluminum construction provides the rigidity and durability required for serious forced-induction combinations, while the dual 103mm inlet arrangement gives builders the airflow capacity needed for extreme horsepower.
```High-Flow Plenum & Optimized Runner Design
```Moving a large volume of air into the manifold is only part of the equation. The MEGAZILLA uses a large high-flow plenum and optimized runner layout to help distribute incoming airflow effectively across the engine.
This performance-focused design promotes improved cylinder filling, responsive airflow and strong mid-to-high RPM power—exactly what is needed in serious race-oriented LS combinations.
```Ideal For
```LS Platform Fitment
```The Granatelli MEGAZILLA is designed for high-performance LS-platform engine builds. Because this is an extreme aftermarket performance manifold, compatibility should be determined by the engine's actual cylinder-head, intake-port, throttle-body and engine-bay configuration rather than by vehicle year or model alone.
Professional Fitment Recommended: Twin 103mm throttle bodies, induction piping, fuel-system components, accessory placement and hood clearance can vary significantly between custom LS builds. Verify the entire combination before ordering.
