AFM & NPP Exhaust Valve Simulators for Chevrolet Corvette C8 (2020–2024)

Description

Got a check engine light from installing an aftermarket exhaust that doesn’t have AFM / NPP (Air Fuel Management) simulators to trick the factory valves? This is the solution!

These AFM / NPP valve simulators are plug and play with the factory valve harness and are easy to zip tie out of the way. Once plugged in, the C8’s ECU is none the wiser that it has an aftermarket cat-back exhaust attached and will not throw a CEL for AFM / NPP valve malfunction.

AFM modules are needed for almost every C8 Corvette going to any aftermarket exhaust. NPP modules are needed if your C8 came from the factory with the Valved Performance exhaust and the aftermarket exhaust you’re choosing is not a valved system

NOTE: If you have a factory base model exhaust, you will need one pair of simulators to avoid a CEL AFM only needed. If you have a factory performance model exhaust, you will need two pairs of simulators to avoid a CEL. AFM and NPP valves are needed. Listing is for one pair.
