alex optima modern lpg & cng systems

ALEX OPTIMA is the first Polish LPG system to meet the stringent EURO 6 exhaust emission standard.

We offer complete conversion kits to enable your car to run on gas. The system is available in several versions and configurations. This makes it easy to adapt it to all indirect fuel injection engines. The system’s most important part is the innovative controllers, i.e. OPTIMA nano, OPTIMA EXPERT and – the latest one in our product portfolio – OPTIMA PICO. They are available in sets that include either the SHARK or TURBOT reducers, which are also well-known on the market. The sets are complemented by FLIPPER, Barracuda and Super B injectors, as well as Ultra360º centrifugal filters.

A  controller designed for simple 3- and 4-cylinder engines. It is a  compact, functional, versatile and affordable autogas computer. Its small size and simplified design make it easy to install and calibrate the system, guaranteeing little interference in the engine’s original layout.



The OPTIMA nano control is a computer that controls sequential gas injection. It is the most advanced device in its class. It is designed for cars with various types of indirect fuel injection systems.

The innovative algorithm of the control precisely adjusts the dose of gas to the operating conditions and engine load in full range of its operation. This way, it reduces gas consumption.

One of the controller’s great advantages is the ability to connect it to a  standard external OBD interface (On-Board Diagnostics – in short: the car’s onboard system that enables self-diagnostics), which helps to perfectly tune the gas system.



The professional OPTIMA EXPERT controller features a  built-in OBD support module and a  pressure and fuel level sensor emulator.

The emulator is fully programmable using the system tuning application. The advanced functions of the controller enable autoadapatation and direct communication with the car’s OBD. This makes OPTIMA EXPERT one of the most mature controllers in the 4-6-8 cylinder class.

A  system proven both in laboratories and on the road

ALEX OPTIMA system components have been subjected to multiple tests, proving that all of them work together optimally. For all system components to work perfectly, the system itself must be installed by qualified professionals. Experienced installers can help you choose the right set of components for your car.

Maximum compatibility

The ALEX OPTIMA kits can be easily installed in almost any car model, and additionally, choosing the original ALEX system gives you the certainty that you are using a  reliable, highest-quality LPG system with all components produced in-house by a  single manufacturer. This is our competitive advantage – we guarantee maximum compatibility of all components we offer.

Professional installation services

Due to its complexity, the process of selecting and installing both the components and the gas system itself should be carried out by an experienced professional with the necessary qualifications. The gas system must be selected carefully based on the vehicle and engine type, and above all, the driver’s expectations. As a  car gas system manufacturer, we work closely with the best workshops that offer LPG system installation services. Use the search engine to find the nearest LPG workshop that can fit your car with an ALEX autogas system.
