I have been looking at aftermarket grid heaters like the one GDP sells that bolts on at the throttle valve.

I like the GDP heater, but it says not for 2019+ trucks on their site.

Black Market Performance makes one that bolts to the throttle valve they list for 2007.5-2022 trucks—just trying to figure out why the one from GDP won't work on a 5th Gen.

Any thoughts?
