LS Throttle Body Adapter 3 Bolt Intake to 4 Bolt

The LS Throttle Body Adapter 3 Bolt Intake to 4 Bolt by ICT BILLET is designed for LS engine builders and swappers who need to upgrade from a 3-bolt intake manifold to a modern 4-bolt throttle body. This precision adapter addresses fitment challenges while ensuring optimal airflow dynamics and seal integrity. It is an essential component for those looking to enhance their engine's performance without the need for custom fabrication.

Constructed from aerospace-grade billet aluminum, the adapter features CNC-ported passages that minimize turbulence and maintain optimal velocity. The 3-bolt mounting pattern secures directly to your existing intake manifold, while the 4-bolt exit flange allows for compatibility with any standard LS-pattern 4-bolt throttle body. This design ensures a straightforward installation process, making it a plug-and-play solution.

This adapter is particularly beneficial for builders of LS1, LS2, LS3, and LS7 engines performing mid-generation upgrades. It is ideal for those converting early 2000s iron-block platforms to newer aluminum manifold designs. Whether you're working on a naturally aspirated hot rod, a turbocharged swap, or a supercharged street machine, this adapter provides the reliability and performance needed for various applications.
