3.3TT Spark plugs

[MNTodd]

OK, so that's the mystery solved then.

It needs to be noted that these plugs will ONLY work on vehicles with the revised coil boot. (Post MY22 if research is correct) Either they squish down more or they have longer springs in them.

Sorry to bring up an old post again, but as I'm reading through this with the Ruthenium plugs already in-hand and a 2019. I was ready to send them back to Rock Auto and exchange for the Iridium IX noted by @SSavage , but if you look at post #5 of this thread, he shows a photo and he has the older style coil pack (with the rubber/plastic/rubber) and these plugs worked for him. So, before I send these plugs back has anything else been figured out on this? I'd sure like to just use what I have. I supposed I should just pull a coil and check for myself, but figured that I would check here first. Thanks
