GFI Control Systems


GFI was born, a private company in 1993, in Kitchener, Ontario, Canada producing various high pressure components for the Automotive and Industrial CNG markets around the world. Following 7 years of rapid growth, GFI was acquired by the Teleflex Corporation and began trading as TeleflexGFI.

In 2002 the GFI brand came to Europe, through the acquisition of AG Autogas in The Netherlands.
This was shortly followed by the acquisition of Koltec Necam in 2003, another leading Dutch company involved in the design, manufacture and supply of bi-fuel (LPG&CNG) engine management systems.

The ensuing years (2003-2009) saw GFI continue to grow and expand its presence and reputation under the management of the Teleflex Corporation.
OEM programs were secured with Ford Motor Company, Volvo Car Corporation, GM (Vauxhall) and Renault.
Vehicle Importers in different European countries also recognized the advanced capabilities of the GFI products. This resulted in supply contracts for Subaru, Mazda, Peugeot, Citroen, Mitsubishi, Hyundai, Chevrolet, Lada and Suzuki.

In 2011, some of the GFI products were relocated to the headquarters of MTM srl, in Cherasco, Italy and some of them stayed in Kitchener, ON,

At MTM, the GFI products include a comprehensive range of alternative fuel components, system-level certified kits and best in class services. MTM continues to provide original equipment manufacturers (OEM), country distributors and aftermarket installers with a rich portfolio of solutions from concept to vehicle integration and assembly.

At GFI in Kitchener, ON, Canada, the product portfolio includes CNG regulators, CNG tank valves and Hydrogen components. Goto to access information on these products.

LPG-Kits from GFI which are out of production

Hereby I make an overview from the kits which are out of production, but from which we have a solution for most of the parts at Van Meenen. For most parts we still have the new spare parts on stock, and if not on stock we can usually repair them.

TeleflexGFI EZ-SGI Sequential Gas Injection

EZ-SGI (pronounced as easy-SGI) was a break-through for the LPG industry and the key to convert vehicles to LPG without cost consuming development projects.

Logo AG SGi


The AG SGI system was a sophisticated sequential injection system. The highly standardised components together with a minimum of electrical connections, make this system flexible.

Necam GSI (Gaseous Sequential Injection)

The NECAM GSI system was a state of the art sequential injection system. It has been using the components below.

The injectors are not produced anymore, but at Van Meenen we have a solution. The 3.4 injectors (mainly used on Cadillac) are still available on stock. We bought the stock from the Cadillac importer when they went bancrupt in Europe.

For the other types of injectors: we can do a revision from them. After the revision the injectors will work again like new.

Necam Mega distributor

The Necam Mega distributor was a part of the Necam Mega injection system.

The item is not produced anymore, but we can still do a revision from it. We can also repair the step engine which is on top of it, both for the standard version as for the Volvo CNG version. Contact us for repair. We can make a special offer for larger quantities.

We do not supply the repair kit seperately anymore. We only do the full repair.
