Description
Granatelli Motor Sports ZILLA Black Billet LS Intake Manifold – 120mm Inlet
Feed your high-horsepower LS engine the airflow it needs with the Granatelli Motor Sports ZILLA 120mm Black Billet LS Intake Manifold. Precision-machined from solid billet aluminum, the ZILLA is engineered for serious naturally aspirated, turbocharged and supercharged LS combinations where airflow, strength and fuel-system flexibility are critical.
Featuring a massive 120mm throttle-body inlet, high-efficiency plenum and runner design, dual-injector capability and a durable black anodized finish, this manifold is built for high-output street cars, drag racing applications and full race combinations operating at high RPM and elevated cylinder pressure.
Important: This is the 120mm inlet version of the Granatelli ZILLA billet LS intake manifold, part number 980120.
Maximum Airflow for Serious LS Builds
The ZILLA 120mm manifold is designed for combinations that demand significantly more airflow than a conventional factory-style intake can provide. Its oversized inlet and performance-oriented internal design make it an excellent choice for large-displacement, high-RPM and forced-induction LS engines where airflow can become a major limitation.
Key Features
- Massive 120mm throttle-body inlet for serious 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-injector capable for high-output fuel systems
- Can also be configured with a standard set of eight injectors
- Includes injector block-offs for single-injector configurations
- Engineered for naturally aspirated, turbocharged and supercharged combinations
- Explosion tank included as an added safety feature
- 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
120mm High-Flow Inlet
The oversized 120mm inlet is designed for LS combinations where maximum airflow is a priority. Large-displacement engines, aggressive camshaft combinations, high-RPM builds and forced-induction setups can quickly exceed the airflow capability of smaller intake and throttle-body configurations.
The ZILLA's optimized plenum and runner design is engineered to move a large volume of air efficiently while promoting consistent distribution between cylinders, helping support improved cylinder filling and power delivery throughout the performance RPM range.
Dual Injector Capability
High-horsepower LS engines can quickly exceed the fuel-delivery capability of a traditional eight-injector system. The ZILLA manifold is designed to support a dual-injector configuration, providing additional fuel-system flexibility for high-boost, high-RPM and extreme-horsepower applications.
For combinations that only require one set of eight injectors, the manifold includes the necessary injector block-offs, allowing it to be configured without using the secondary injector locations.
Explosion Tank Safety Feature
Aggressive boosted and race applications can experience sudden intake pressure spikes or backfire events. The ZILLA includes an explosion tank as an additional safety-focused feature for demanding high-horsepower combinations.
The system is designed to provide an additional controlled area to help manage sudden intake pressure events and reduce stress on the manifold and surrounding components, making the ZILLA especially well suited for serious boosted and race-oriented LS builds.

CORE CHARGES
Our exchange program is very simple and allows you to receive chrome plated wheels or powder coated calipers without unnecessary down time to your vehicle. We first send you a set of our high quality chrome plated GM wheels or powder coated calipers to have installed. The best way to purchase is with a credit card. We initially charge you for the Chrome Plating
(wheels) or powder coating (calipers) plus a refundable core charge.
You must return your undamaged cores within ten (10) days, we then issue you a full core credit within ten (10) days of receiving the product. Cores returned late (after the 10-day period) will be charged a $30.00 (per day) late fee. There will be a $100.00 stripping fee on painted caliper cores. To insure the highest quality available we only exchange GM products and they must be for the same style and year. Any damages will be deducted from the core refund. You may contact SR1 Performance for return shipping assistance.
