WOT is normally a very bad situation. In ECU-controlled cars, enrichment happens, and the AF ratio is richened to the point where it's no longer being efficient. 80% seems to be the max throttle angle.

In carb'd cars, it just opens an enrichment circuit which is normally uncalibrated to a specific AF ratio, and dumps some fuel in there unmetered to aide in cooling the engine under high load.

Again, 80% (depending on carb config) is usually about the cut-off. In either event, K&N still doesn't make any of these claims on their own.
