What is a Imrc delete?
The second generation (2015-2017) and third generation (2018+) CMCV/IMRC delete lock outs allow you to remove the bulky factory vacuum pods and pin the intake manifold doors up for maximum airflow at all engine speeds. If you are using a power adder, this is a must.
What is Ford Imrc?
The Intake Manifold Runner Control (IMRC) is an electrically actuated system consisting of a motorized actuator with an attaching linkage for each housing on each bank. The linkage attaches to the housing butterfly plate levers. Each IMRC housing is an aluminum casting with two intake air passages for each cylinder.
What is the purpose of Imrc?
The IMRC system is designed to boost both fuel economy and engine performance. A faulty IMRC valve can prevent proper system operation, leading to a reduction in gas mileage.

What is an IMRC valve and how does it work?
Basically, the IMRC valve is the part of the system that opens and closes the flaps inside the intake manifold. Depending on the layout, the engine may have multiple IMRC valves or have only one valve. It’s important to note that automakers have a bunch of different names for their IMRC valves.
Should I change the IMRC on my ROUSHcharger?
The F150 Roushcharger uses the the IMRC to control boost dump, so don’t change it with IMRC deleting in mind – rather change it to control boost coming on at lower throttle positions. Personally, I would not use HP Tuners to program a Roushcharged F150, there are too many tables missing for a good, full and proper Roushcharger tune. Having fun!
What does IMRC mean on a Ford?
