The engine and all CNG fuel system components are engineered to meet GM’s rigorous standards for reliability, dependability and safety. GM’s validations tests include: full barrier testing (six separate tests), 10–year corrosion, mud trough, water fording, hot-weather evaluation (including trailering), cold-weather chamber testing, altitude testing and fuel gauge accuracy among others.

Independent Aftermarket Program
Are you adding GM OEM CNG Trucks and Vans to your fleet and looking to take advantage of the cost savings on your existing vehicles as well? We’ve got you covered! IMPCO Automotive engineers, designs, and manufactures the components in our CNG and LPG aftermarket systems. This allows us to engineer total compatibility into every system from testing and calibration through production and installation. This is not truly achievable with the “off-the-shelf” components used by most aftermarket companies. This superior engineering means components are matched for dependability, performance, efficiency and improved cost savings. Best of all these systems can be installed locally via one of our Certified Installers to minimize downtime in your fleet. Contact our nearest certified installers for a complete list of options available.
