These high horsepower design intake runners fit the FAST LSXR 102mm intake manifolds for rectangle port applications. Provide excellent mid-range and high rpm horsepower for modified street/track oriented vehicles.
The new interchangeable, complementing runners are designed specifically for LS3, L99, L76 and L92 (rectangle port) engines that are built for high performance applications. The High HP Runner Set is based on Daytona Prototype intakes and utilizes newly designed runners, which are shorter and straighter than conventional versions. The High HP version has been proven to make 8-10 horsepower over the original LSXR manifold with a 500-1000 RPM shift up in peak horsepower on LS3 performance engines. However, it maintains all of the same features and benefits of the standard LSXR version.
- This item includes ONLY the 8 High HP interchangeable runners, without the intake manifold
