Air filter fitment - ZR-1 Net Registry Forums

Sooo, changing my air filter. Brand new AC Delco. Bought on line, but looks like an official GM sticker on it. It appears the filter is about an inch taller than the plastic half of the air box. It's not too thick, but too big. It doesn't fit properly and won't seal. The K&N I took out wasn't great, but better. I bought three filters and they all appear to be the same. Is it the part, or the operator? Maybe my air box is too small???
