AFIS Injectors
The AFIS Injectors collection at Prime Speedworks is focused on high-flow fuel injectors for serious street, race and motorsport engine combinations. AFIS positions its injector range for racers using pump fuel, race fuel, ethanol and methanol, with the brand supporting drag-and-drive, heads-up, bracket and high-horsepower racing applications.
Prime Speedworks stocks AFIS Gen2 injector options including 180 lb/hr, 250 lb/hr, 400 lb/hr, 600 lb/hr and 800 lb/hr injectors, along with AFIS injector O-rings and supporting components. Current Prime Speedworks listings include AFIS Gen2 injectors rated from 1692cc through to 6320cc, giving builders options across tough street cars, ethanol combinations, methanol race engines and serious high-horsepower packages.
AFIS Gen2 injectors are promoted with features such as one-piece construction, no internal O-rings, stainless steel construction, flow data at the industry-standard 43.5 PSI / 3 Bar reference pressure, flow-matched sets, excellent idle characteristics and linear operation to 97% duty cycle on selected models. Prime Speedworks’ AFIS Gen2 400 lb/hr listing also notes compatibility with methanol and ethanol applications, with verification recommended for ethanol setup selection.
Injector selection is not just about fitting the biggest injector possible. The right injector needs to suit the fuel type, base pressure, ECU driver strategy, impedance, idle quality requirements, horsepower target, number of injectors, duty cycle target, fuel pump capacity and intended motorsport use. A poorly matched injector can create tuning difficulty, weak idle control, poor fuel delivery, unstable air-fuel ratios or a fuel system that runs out of headroom when the engine needs it most.
Prime Speedworks supports AFIS Injectors with a practical, tuner-aware approach. Whether the build is a turbo 2JZ, RB, Barra, LS, Honda, Hemi, small block Chevrolet, big block Chevrolet or custom race engine package, we focus on supplying an injector that works with the full fuel system and ECU strategy — not just a flow number on a box.

Why buy this collection from Prime Speedworks
Fuel injectors are one of the most important parts of any serious EFI combination. If the injector is wrong for the fuel, ECU, pressure, horsepower target or idle requirement, the tuner is fighting the car before the engine ever gets near full power.
Prime Speedworks supplies AFIS Injectors with a focus on correct product selection. We look at the full combination — fuel type, boost pressure, base fuel pressure, ECU compatibility, injector impedance, target horsepower, cylinder count, fuel pump capacity, regulator setup and intended racing use.
For Australian racers, workshops and tuners, this means access to serious injector options backed by practical performance understanding. Whether the goal is a clean-idling street car, a tough E85 turbo build, a methanol drag car or a high-horsepower race package, Prime Speedworks can help supply the AFIS injector setup that makes sense for the job.
This is fuel delivery hardware for builds where consistency, data and tuning confidence matter.
