Fast Electronics Lsxr High Hp Intake Manifold Runner Set

Please note that this item exclusively comprises the High HP interchangeable runners and does not include the intake manifold.

With a patented removable runner design and the introduction of two additional runner sets, FAST® LSXR™ 102mm Intake Manifolds have become the most flexible options on the market for shifting torque and horsepower gains to a higher RPM compared to the original version. In addition to the original FAST® LSXR™ 102mm Intake Manifold & Runner Set, High HP and Race versions are now available. The new interchangeable runners, designed specifically for LS3, L99, L76, and L92* engines built for high-performance applications, provide enhanced versatility.

The High HP Runner Set, based on Daytona Prototype intakes, features newly designed runners that are shorter and straighter than conventional versions. Proven to deliver 8-10 horsepower more than the original LSXR™ manifold, the High HP version achieves a 500-1000 RPM shift up in peak horsepower on LS3 performance engines while retaining all the features and benefits of the standard LSXR version.

On the other hand, the Race Runner Set boasts a short and straight runner design comparable to aluminum four-barrel intakes in terms of horsepower potential. This manifold setup utilizes a race version of standard runners designed for all-out high RPM performance, making it ideal for race vehicles with substantial performance modifications and race converters. The Race version offers a 15-30 horsepower gain with a 1000-2000 RPM shift up in peak horsepower, albeit at the expense of some low-end torque.

The interchangeable runners are available in kits, allowing manifolds to be configured as the original LSXR™ with standard street runners, or the new High HP or Race models. A master kit is also available, featuring an intake manifold assembly and all three runner options.
