from Routineer;
Ordered a pair of K&N filters for the Z8 for about $100. Had good results with K&N on an M3 and expected the same. Kinda like the "voooomp" sucking sound when I'd get on it, and it does promote easier breathing.
The Z8 airboxes are a little tedious to open, and don't clear the headlight housings without a struggle. Could scratch them going back on if I wern't careful. Might of been better if I disconnected the big hoses that feed the manifold airbox on the engine block. Put the filter elements in and discovered that they fit real sloppy. Then checked the box and discovered the instructions (uh, duh!) for the grey foam adhesive/paper-backed gaskets that have to be installed in the filter box prior to installing the filter elements. We're talking cheap 1/8" die-cut foam about 3/8' wide to fit around the perimeter of the inside of the air box where the more rugged foam filter elements normally seat. They didn't stick that good due to the loose hydrocarbons (mold release?) on the plastic airbox, and I'm sure that they wouldn't last the alleged million miles life of the filter elements themselves. These gaskets will probably wear out or tear after just a few filter removal/cleaning/re-installs.
Bottom line - I put them both back in the box, reinstalling the OEM filters, and sent them back for credit. Hey, K&N man - lose the tux and buy more tooling! If it doesn't fit, don't sell it.
Meanwhile, assuming you're not counting the chrome rear license plate frame, the Nurburgring sticker and the wired-in Escort 8500 mount, the Z Acht is still box-stock, not that there's anything wrong with that!
