Hard acceleration causes pops and shuddering feel

Noticing that when I do hard acceleration, the car pops a lot and there's a sputtering sensation if that makes sense. No CEL or temp readings, otherwise drives fine. Hit a speedbump hard the other month and worry it could be related to that. I also had my spark plugs changed a few weeks ago.

Turns out I had the wrong plugs. I guess somehow the part number for the plugs is also the same for a platinum plug they use for old Taurus's. Now that I got the correct iridium ones in, much better now and no issues. I should've double checked the box when I got them from parts.
