ZR1 Ultimate Cooling Package Maximum coolant capacity. Maximum coolant flow. Maximum performance. Heat is the enemy of horsepower. As boost levels increase, so do intake air temperatures, making an upgraded intercooler system one of the most important investments for any high-performance C6 ZR1. The Omni Motorsports Ultimate Cooling Package has been designed for customers who refuse to compromise on cooling performance. By combining the industry’s best components with a custom-built plumbing system, this package dramatically increases coolant capacity, improves coolant flow, and helps maintain lower intake air temperatures during repeated street pulls, road course sessions, and drag strip passes. Unlike traditional cooling kits that rely on restrictive factory plumbing, our system utilizes 1-inch Vibrant Performance hose for both the feed and return lines. The system is routed through Peterson Fluid Systems Y-manifolds and push-lock fittings, allowing coolant to flow efficiently into both intercooler passages of the supercharger while minimizing restrictions. Whether you’re running a ported OEM blower or a Kong Performance 2650, this package is built to provide the maximum cooling performance available for the LS9 platform. Package Includes: Xtreme CFM Trunk Tank Kit OMS High-Capacity Heat Exchanger with -16AN fittings Kong Performance Gen 3 Lid with dual -12AN bungs 1-inch/3/4inch Vibrant Performance feed and return hose Peterson Fluid Systems Y-manifolds Premium push-lock fittings and plumbing components Benefits Increased intercooler coolant capacity Improved coolant flow through the entire intercooler system Reduced intake air temperatures (IAT2) Improved consistency during repeated pulls and track use Helps minimize heat soak Supports high-boost and high-horsepower LS9 combinations Designed for both ported OEM superchargers and Kong Performance 2650 superchargers If you’re building an 800+ horsepower ZR1, cooling is no longer optional—it’s essential. This package combines the highest-quality components available into one complete solution, giving your LS9 the cooling capacity needed to perform consistently when it matters most.
