No, its a perfectly normal question. Just to give you a little background. On a fuel injected car, when you step on the gas pedal, you aren't really giving the car gas. That pedal opens up your throttle body, sucking air in through the intake. Depending on how hard you press the gas, controls the amount the throttle body opens. When the air comes in through the filter, in passes through you MAS (mass air sensor). This senses how much air is coming in and tells the ECU(computer). The ECU then calculates how much gas in needs to relay to the engine to match the amount of air going in, to give you proper combustion(giving you propulsion). So the FIPK(fuel injection performance kit) is a dumb name K&N(the brand) gave to this specific filter. The more air = the more fuel being injected into your engine. Therefore, rather then calling it a performance filter, they decided to go with this name. But trust me, all it is, is a cone filter, and a metal adapter that allows you to bolt your filter directly to the MAS. On other cars(not 3000gts) some FIPKs come with plastic heat shields to put around your cone filter to keep the hot air generated from the motor from going into the intake. But on the 3000gts, its only the filter and adapter. There is nothing physically done to your fuel injectors.
