our mission
WING Fuel Systems delivers EPA-certified CNG and RNG conversion systems for commercial fleets — built on Westport™ technology trusted in millions of vehicles worldwide. We offer both "No Range Anxiety" bi-fuel conversions (natural gas first, with full gasoline backup) and dedicated CNG-only systems, giving fleets the flexibility to choose the right solution for their operation. Either way, fleets cut fuel costs significantly without changing routes, adding infrastructure, or accepting range limitations. Cleaner fuel. Lower cost. No compromise.
