Granatelli Motor Sports ZILLA Black Billet LS Intake Manifold – 105mm Inlet

Feed your high-performance LS engine the airflow it needs with the Granatelli Motor Sports ZILLA 105mm Black 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 dual-injection design with 16 injector ports (plugs included to run 8 injectors), 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, featuring a dual-injection design with 16 injector ports, plugs included to run 8 injectors.

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 offering a dual-injection design with 16 injector ports, plugs included to run 8 injectors. 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
  • Dual-injection design with 16 injector ports, plugs included to run 8 injectors
  • Rated to 45 psi of boost for turbocharged and supercharged builds
  • Clean and efficient layout for naturally aspirated, turbocharged and supercharged combinations
  • Black anodized finish for corrosion resistance and a clean 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.

Dual-Injection Configuration

This intake manifold uses a dual-injection design with 16 injector ports, and injector plugs are included so you can run 8 injectors when your fuel system does not need all 16.

It is ideal for performance LS combinations that require substantial airflow, with the flexibility to run 8 injectors using the included plugs or to use the dual-injection ports as the build requires.

Injector Fitment

The ZILLA uses LS3/LS7/LSA-style length fuel injectors with LS3/LS7/LSA-style O-rings, whether you run 8 injectors with the included plugs or fill all 16 ports.

Injectors that fit include Fuel Injector Clinic LS3/LS7/LSA-style injectors (available in flow ratings such as 540cc and 1440cc high-impedance), Fuel Injector Development injectors from 850cc to 2,200cc in the LSA/LS3/LS7/L76 body and O-ring size, and LS3/LS7-style injectors from Injector Dynamics, DeatschWerks, Bosch and Chevrolet Performance. Size the injectors to your horsepower target and fuel type.
