K&N, the world leader in developing premium air filters, offers the K&N Air Filter. The air filter is necessary for the air intake system of your Nissan 300ZX. The job of an air filter is to strain the air that goes into the engine to get rid of damaging particles which are present with it. The air that enters the engine has to be free from dirt because it will be fused with the fuel during combustion. Without the air filter, the fusion of contaminated air with the fuel will result to an inefficient fuel/air mixture. So you see, the air filter has to be in shape at all times to supply fresher air to the engine and help in boosting its performance. The air filters from K&N are very much reusable because of the special material used in their construction. The stock air filter of your 1990-1996 Nissan 300ZX ought to be replaced, especially if it is all worn-out. The K33332036 K&N Air Filter makes sure that you get quality performance all the time.
