Why Upgrade to a Ported LSA Snout?

The throttle body is one of the first places air enters your supercharger system. When you’re running a larger engine, more boost, or a serious LS performance combination, improving the airflow into the blower can be worthwhile.

This snout has been ported for a larger 102mm–103mm throttle body, giving you the opportunity to move beyond the smaller factory-style inlet and build a higher-flowing LSA supercharger setup.

It’s a great option for customers running:

• LS3 and LSX engine builds
• LSA supercharged LS swaps
• High-performance Camaro builds
• Custom Corvette and CTS-V projects
• 408 stroker LS engines
• Big-cube LS combinations
• Drag racing and street performance builds
• Custom 102mm or 103mm throttle body setups

Built for Serious LS Performance

If you’re already investing in an LSA supercharger, upgraded throttle body, intercooling system and supporting modifications, this is the type of component that can help complete the combination.

Rather than replacing your entire supercharger, you can upgrade the inlet area and pair the LSA blower with a larger throttle body suited to your build.

The ported snout is shown in detail in the photos, including the enlarged inlet area and machined surfaces. The drive assembly and exterior condition are also visible so you can inspect the part before purchasing.

Perfect for Custom Builds

This is not simply a stock replacement for someone looking to keep a completely factory configuration. It is better suited to enthusiasts who are building an upgraded LSA supercharger system and want to run a larger throttle body.

Whether you’re putting together a supercharged 408 LS stroker, upgrading an LS3, or building an LSX-powered street/strip car, this can be a useful piece of your overall airflow package.

What You Get

Included:

• Ported LSA supercharger snout
• Enlarged inlet suitable for 102mm–103mm throttle body applications
• Snout/drive assembly shown in the photos
• Exact item pictured

Throttle body is not included unless specifically stated in the sale.

Important Fitment Information

Because this is a ported/custom LSA supercharger component, buyers should verify their existing supercharger, throttle body, mounting configuration and overall setup before ordering.

A 102mm or 103mm throttle body does not automatically make more power on every engine. The best results come when the entire combination—engine, cylinder heads, intake, supercharger, exhaust, fuel system and tune—is matched to the desired power level.

Don’t Settle for a Restrictive Inlet

If you’re pushing your LSA supercharger beyond a basic factory setup, upgrading the inlet can be an important part of building a better-performing combination.

This 102mm/103mm ported LSA supercharger snout is a great choice for LS and LSX enthusiasts looking for a larger throttle body solution and a more performance-focused supercharger setup.

Serious LS build? This is ready to become part of it. Check the photos carefully, confirm compatibility with your setup, and reach out if you have questions about fitment.
