I check with K&N and they do not make any intake kits for a 280 ZX. So does any body know who does? There's obviously gotta be something

more better than that Auqa colored filter box...right?

No, not "more better." The ZX box is already a cold air intake, and putting on an "intake kit" won't do anything but change the sound coming from under-hood. Put in a K&N drop-in filter.

go on ebay and get one for 25-30 depending on your year, just a simple short ram, then bring it down to autozone, and get a k & n to fit.
