LS1 High-Flow 102MM Intake Manifold — Bolt-On Performance Upgrade

The LS1 is already a legendary platform — this manifold helps it breathe the way it was always meant to. Engineered with a 102MM bore and precision-ported runners, this high-flow intake manifold maximizes air velocity and fuel atomization across the RPM band, delivering improved throttle response and measurable horsepower gains without the complexity of forced induction. Cast from durable aluminum alloy, it bolts directly to factory mounting points with no modifications required, and includes all gaskets and hardware for a complete, straightforward installation.

Key Features

• 102MM high-flow bore — Larger bore diameter increases airflow volume into the engine, supporting improved power output across the RPM range.
• Precision-ported runners — Optimized runner geometry maximizes air velocity and fuel atomization for more complete combustion and better throttle response.
• Improved horsepower & throttle response — Delivers measurable performance gains on naturally aspirated LS1 builds without requiring complex tuning or forced induction.
• Durable aluminum alloy construction — Lightweight yet strong, built to withstand the thermal and mechanical demands of performance engine use.
• Direct bolt-on fitment — Designed for factory LS1 mounting points with no modifications required for a clean, straightforward installation.
• Complete hardware included — All necessary gaskets and hardware included so you have everything needed to complete the install.
