My 2018 5.3L truck have a K&N Air Intake System 77 Series and Flowmaster Outlaw Exhaust System (Super 10 Muffler). Wondering if its worth to add a Airaid 200-543 throttle body spacer or nah??

pretty much no fuel injected application that those work on. probably the worst form of snake oil in the aftermarket. Now on a carb to increase the length of the intake tract on an single plane manifold that is different. everything else - total garbage. Give you as much HP gain as a set of stickers do.
