• AFIS – Gen 2 250 lb/hr Fuel Injectors
  Flow Matched | Stainless Steel Construction | Low Impedance | EV1 Connector

  The AFIS Gen2 250 lb/hr Injectors are engineered for extreme-performance applications where consistent fuel delivery, durability, and tuning stability are critical. Compatible with pump gas, race fuel, methanol, and ethanol (E85), these injectors support a wide range of high-horsepower builds. Because pump and race fuel formulas can vary, AFIS encourages customers to call for verification to ensure optimal compatibility with your specific setup.

  Designed as the ultimate replacement for Siemens DEKA injectors, the AFIS Gen2 series offers superior construction quality, improved corrosion resistance, and more consistent flow—making them the go-to upgrade for builders wanting increased reliability without changing connectors or layout.

  Each injector features a one-piece, no–internal–O-ring design, delivering OEM-grade reliability and eliminating common failure points found in multi-piece injector bodies. The stainless steel construction ensures exceptional corrosion protection and long service life, especially in alcohol-based fuel environments.

  With a standard 1.85" body length, EV1 connector, and low-impedance (peak & hold) configuration, these injectors integrate seamlessly into existing systems. Published flow data uses the industry-standard 43.5 psi (3 bar) pressure reference, providing honest, credible numbers you can tune around confidently. Every set is precision flow-matched, improving cylinder-to-cylinder consistency, power production, and engine safety.

  Thanks to excellent idle characteristics and linear operation up to 97% duty cycle, these injectors offer exceptional flexibility, delivering stable fueling from low-load cruising to full-throttle demand. Backed by a Limited Lifetime Warranty, they offer long-term confidence for demanding builders and tuners.
