Why fuel injection?

Anytime an engine generates more than 260 HP we believe that fuel injection provides the needed even fuel distribution on each cylinder to make your flying worry free. You will achieve more predictable CHTs and EGTs and enjoy a smoother ride with reduced vibration. This minimizes premature component failure. Did we mention 0% carburetor ice issues?

We offer several products that will enhance your aircraft and add more pleasure to your flying. During an engine upgrade we are able to install other products and accessories efficiently since we start with a clean slate.
