1 Plate is required for each AFM/ NPP valve. Most V8 systems require 2 plates.
MRT has designed and manufactured a simple solution for customer's who want to upgrade their exhaust on a vehicle that has factory installed AFM/NPP devices. MRT offers this quick, easy and simple solution to simulate the Active Fuel Management (AFM) valve function or dual mode exhaust (NPP) on the 2015 -2020 Corvette and Camaro without causing a Check Engine Light (CEL)!
How it works: it is a plate that is a direct bolt on mount to the Active Fuel Management electric motor. It acts as a dummy mount for the AFM valve actuators that feels right to the car computer but actually has no valve in the exhaust. Once you install the plate on the AFM valve, simply plug the motor into the harness and safely zip tie the valve in a safe location so it won't get damaged by moving parts. It's that simple. No tune required and you're ready for a test drive!
This plate is designed for use with aftermarket cat-back or axle-back exhaust systems. Like all MRT engineered, and manufactured exhaust products, the MRT AFM/NPP Power Plate™ is designed and built to last. We stand by our exhaust products with full confidence and that is why we provide our industry-leading LIMITED LIFETIME WARRANTY on workmanship and materials.
The MRT AFM/NPP Power Plate™ is designed and handcrafted in Plymouth, MI by MRT. We take great pride in what we do and we let the quality of our work speak for itself. ALL MRT branded products are made in the USA.
