What is the correct part number for EGR plugs?

I ordered some of part number 17199-PT3-AHM from the dealer a couple days ago and went to install them, but they are a bit too small. Imagine my surprise when I went to install one and it just dropped right down into the EGR channel.

I measured their diameter and they're roughly a millimeter smaller than the plugs I took out. Keep in mind the old ones were probably a bit larger before they were installed.

I looked around on the internet and this seems to be the correct part number, but they're just way too small. Anyone know which one I should've gotten?

Funny you mention this. On page 17 in my MR thread I stated that exact part number. They fit right in when I performed this on the H22a intake manifold. I’m pretty sure these work with the Fseries as well. I can check when I get back to Florida on Wednesday. But it sounds like it may have been done before and they widened the holes a little too much.

I did find quite a bit of carbon in the runners, so it's very likely this was done before. Other than drilling out the holes, which I'd like to think no one in their right mind would do, they should not be enlarged by installing these plugs.
