FAST Fuel Rail OEM Car Kit For LS1/ LS6 Engine With LSXR 102MM Intake Manifold

This FAST Fuel Rail Kit (146021-KIT) was designed for GM LS1 and LS6 engines with a FAST LSXR 102mm intake manifold. Don't be fooled by the OEM look, though, because this Fuel Rail Kit can really pack a punch with its high-performance capabilities. 

Features and Benefits:
- Fits LS1 and LS6 Engines Using the LSXR Intake Manifold
- Includes LS2 Style Rails, Spacers, and Bolts
- OEM Look with High-Performance Capabilities 
- Compatible with Factory or Aftermarket Injectors

The FAST Fuel Rail Kit consists of GM LS2-Style fuel rails, spacers, and bolts. The LS2-style rails are preferable for a number of reasons, not least of which is increased fuel volume. Greater fuel volume dampens fuel delivery pulses while making more fuel readily available for factory or aftermarket injectors.
