Where's the best place to tap into the intake manifold to introduce seafoam? 2015 SE, 2.5

Totally curious as to why you are trying to do that on a 7 year old car. Is there a problem that you're trying to solve? If i were to do it though I'd go through the part of the hose that connects to the throttle body.

Anywhere beyond the throttle body is not going to distribute evenly to the cylinders.

OTOH, it won't matter if one cylinder gets more since it doesn't do anything but generate smoke anyways.

Seriously... don't bother. It's not a bad product to use on a toothbrush to clean the residue from the throttle body, but it's not doing anything to the "top end"

My brand new GDI cars get a spray/foam can cleanup EVERY year.
My older MPFI, TBI, and carb'd cars got it every few years. Decarbon carbonclean were some of the earlier ones that improved MPG, drastically reduced emissions, and improved drivability.

Toss full can of Seafoam into gas tank at next fill up.

Pick up a spray cleaner to avoid idiocracy, which is the smoke show often posted on boobtube

How much of the can would you use? It's got 150k on it, just trying to refresh what I can.
