Granatelli Motor Sports ZILLA Silver Billet LS Intake Manifold – 105mm Inlet
Feed your high-performance LS engine the airflow it needs with the Granatelli Motor Sports ZILLA 105mm Silver Billet LS Intake Manifold. Precision-machined from solid billet aluminum, this manifold is engineered for serious naturally aspirated, turbocharged and supercharged LS combinations where airflow, durability and clean fuel-system packaging matter.
Featuring a large 105mm throttle-body inlet, high-efficiency plenum and runner design, and a single port injection configuration, this manifold is built for high-output street cars, drag racing applications, LS swaps and track-driven combinations looking for strong airflow and dependable performance.
Important: This is the 105mm inlet version of the Granatelli ZILLA billet LS intake manifold, designed for a single port injection / standard eight-injector configuration.
Performance Airflow for Serious LS Builds
The ZILLA 105mm manifold is designed for LS combinations that need significantly more airflow than a conventional factory-style intake can provide, while still maintaining a practical single-injector fuel-system layout. Its oversized inlet and performance-oriented internal design make it a strong choice for street performance, drag racing and boosted LS applications.
Key Features
- Large 105mm throttle-body inlet for increased airflow capacity
- Precision-machined from solid billet aluminum
- Designed for high-horsepower LS street and race applications
- High-efficiency plenum and runner design
- Engineered to improve airflow distribution and cylinder filling
- Designed to support strong mid-to-high RPM power delivery
- Single port injection configuration for a standard eight-injector fuel system
- Clean and efficient layout for naturally aspirated, turbocharged and supercharged combinations
- Silver billet finish for a clean, high-end performance appearance
- Includes gaskets and installation-related components
- Precision-machined for professional installation and consistent fitment
- Made in the USA
105mm High-Flow Inlet
The 105mm inlet is designed for LS combinations where airflow, throttle response and horsepower matter. Aggressive camshaft combinations, high-RPM engines and boosted setups can quickly exceed the capability of smaller intake and throttle-body configurations.
The ZILLA's optimized plenum and runner design is engineered to move air efficiently while promoting consistent cylinder-to-cylinder distribution, helping support improved cylinder filling and stronger performance across the usable RPM range.
Single Port Injection Configuration
This intake manifold is designed around a single port injection / standard eight-injector configuration, making it a great fit for builders who want a clean, straightforward fuel-system setup without the complexity of a dual-injector arrangement.
It is ideal for performance LS combinations that require substantial airflow while retaining a more traditional port-injection layout for easier packaging, tuning and overall installation.
