It shouldn't as I just bought a replacement from www.hondapartspro.com for about $110 (they charged eBay shipping rates!! $35!!), they stated it was for all models of the I4. On my order sheet it said "Sedan", so I called to confirm it would work for a Coupe and they said yup all models. It's got the bunghole for the O2 sensor, etc. I don't believe, however, that it's an authentic Honda OEM part, but I don't care. $150 vs $350.
