The KSM Motorsports 8 x 650cc fuel injectors are engineered for enhanced fuel delivery in high-performance vehicles. Each injector offers a flow rate of 650cc/min at 3 BAR (60 lb/hr) and is meticulously flow-matched to a discrepancy of 1%-1.5% for consistent performance. These injectors operate at high impedance and are E85 safe, providing versatility for various fuel types. Constructed with Viton o-rings and a USCAR electrical connector type, these injectors are built for durability and reliable connection. The dimensions include an overall length of 53 mm, a body diameter of 17 mm, and an o-ring to o-ring distance of 45 mm. The upper o-ring is 15 mm, and the lower o-ring is 14.5 mm. These injectors are specifically compatible with the following GMC Sierra models: 2000-2007 Sierra 1500 V8 (4.8L, 5.3L, 6.0L), 2001-2007 Sierra 1500 HD V8 (6.0L), 2000-2007 Sierra 2500 HD V8 (6.0L), 2001-2007 Sierra 3500 V8 (6.0L), and the 2007 Sierra 3500 HD V8 (6.0L) and 2007 Sierra V8 (5.3L). Every fuel injector is tested by an ASNU machine before delivery, ensuring quality and performance right out of the box.
