2011-2016 Duramax LML Resonator Plate - John C Garage

Our very own resonator cap for your 2011-2016 LML Duramax! This resonator plate is made from a high temperature carbon fiber nylon blend to accommodate extreme engine bay temperatures! We have done extensive testing on these plates and even in direct contact with a torch flame, it did not break down or soften unless sustained for a period of time. Brand new countersunk hardware is included for a nice clean fit and finish!
