The Airtronic S3 D2L kit is designed to minimize setup time. The plug-and-play system comes with pre-configured wiring and marine-grade components, including a fuel metering pump, stainless steel exhaust, combustion air silencer, and more.
With an existing fuel line, you don't need additional equipment, which saves time and simplifies installation in tight spaces.
