Super B injector


Extremely efficient and versatile LPG/CNG gas injector, dedicated to demanding engines, both with direct and multipoint injection.

The Super B injector is the advanced evolution of the Barracuda injector. It is designed for engines that require linear operation throughout the entire range – both at low and high speeds. The injector is able to handle low speeds and high loads, without changing/reaming the nozzles. In many cases, especially in direct gasoline injection engines, such an injector is the only option to properly fuel the car. We also gain with larger capacities, because after increasing the pressure on the reducer, the injector’s efficiency increases, without compromising the idle running stability.

Super B injector perfectly supports overworked engines. In this case, the injector delivers a very small dose of gas when the engine is running at no load (idle and cut-off), while still providing sufficient performance at maximum load.

The construction of the Super B injector uses modern fluoropolymer sliding coatings with non-stick and anti-freeze functions, as well as seals made of fluorinated rubber compounds. Thanks to this, the injector elements are resistant to the harmful effects of physical and chemical factors, and the risk of sticking impurities from the gas fuel is minimized.


  • Available in a version for single assembly – with or without an adapter, as well as combined into 2, 3 and 4 – cylinder rails.
  • Linear operation from 1.6 ms!
  • Work dynamics increased by 40% compared to the Barracuda injector
  • Maintained a sufficiently low dose, while maintaining the final efficiency
  • Resolves the issue of unstable performance at low RPMs
  • Dedicated to cars with both direct injection (ALEX IDEA system) and multipoint injection (ALEX OPTIMA)
  • Manufactured and tested in accordance with the American SAE J1832:2016 standard, created to standardize the production and measurement of petrol injectors
  • No need to use reducing nozzles and their reaming (only pressure regulation is recommended)
  • High-tech fluoropolymer sliding coat with non-stick and anti-freeze function
  • If there is a need, the efficiency of the Super B injector can be adjusted with the pressure of the reducer
  • Small dimensions and quick assembly
  • Discretionary equipment configuration thanks to wide range of supplying connectors, injection rails and gas distributors
