Well, yeah, I didn't just change the element, I went to an open-element K&N in a pretty chrome housing...
Oh, and it's five inches tall.
We also have one on our '94 Z28, the whole "FIPK" (Fuel Injection Performance Kit) setup - and it was good for at least two tenths on the quarter mile. Again, probably, most of the difference was from going to filter-box to open-element, but still...it's worth it.
