Just came across this thread while Googling something.

The OEM Odyssey emble for the 03 body style is huge, I have yet to find a replacement RED H fro the back, let aloone the front. I have always put Red H's on the back of all my Honda's and it eats me up I can't find one for my wife's Odyssey.

I have an 03 Accord and I found the Red H for that one, it is actually the same size as the RSX emblem. And the first thing I did was size it to the Emblem on the back of the Odyssey before I installed it. The Odyssey is still bigger.

At the time, that Odyssey OEM H was the biggest I have seen, I think the new Odyssey's are even bigger.

I couldn't believe the size of the OEM H on the back of the Accords when I saw them. I personally like the large emblems...
