Description
Part #: 32107-1
FAST Precision-Flow Fuel Injectors deliver the outstanding idle quality, unparalleled flow consistency and durability essential for high performance EFI engine applications. Engineered to yield faster throttle response, reduced clogging and superior fuel atomization, Precision-Flow Fuel Injectors are manufactured to the tightest tolerances in the industry. FAST also offers Precision-Flow Fuel Injectors specifically for GM Gen IV engines that are the highest flowing injectors available for these applications and are uniquely designed for direct installation into LS2 and LS3/LS7/L76/L92/L99-style engines. Available in two different height configurations and a wide range of flow rates, the injectors are correctly sized (shorter than common LS1/LS6 injectors) and feature the correct EV6/USCAR connector, enabling a hassle-free plug-in operation.
Features:
- Improved idle quality, throttle response and flow consistency
- Direct install in many EFI manifolds including GM LS3 and LS7 as well as the L76, L92 and L99.
- Compatible with FAST LSXr manifolds when used with appropriate spacer kits
- Special sized O-ring included for drop-in use in GM Gen III and IV LS manifolds
- At 220 lb/hr (@58 PSI, 210 @ 43.5 PSI) the FAST Precision Flow 240 lb/hr Fuel Injectors are some of the highest flowing injectors available.
- E85 & Methanol compatible for use in high-performance EFI applications
- Electrical connectors and pre-assembled pigtails are available for adaptation to other fuel injector harnesses
- Fuel injector spacer kits adapt the Precision Flow 240 lb/hr injectors to other manifold/rail combinations with taller installed heights.
The FAST Precision Flow 242 LB/Hr LS3/LS7 profile injector provides a significant increase in fuel flow over stock while retaining drop-in compatibility for use in GEN III/IV LS manifolds.
