Prevent a check engine light on your C8 Corvette with our AFM & NPP Valve Simulators. When you install a aftermarket exhaust that doesn't have valves the computer system will have a check engine light appear. Our direct plug and play simulators will prevent your check engine light from appearing on your dashboard.
*Note: Yes we know, factory valves are 4/5 pin connector. Simulators only need 3 connection pins to do the function of fooling the car for no CEL. Don't over think it.
DESIGN UPDATED 2022 - Idea of install is the same, except you get 4 connectors vs 3 in the video.
