is it hard to replace the air intakes for a 1993 300zx.
No, is not. You need to unscrew a couple of bolts to take off the nose panel first. Then you, unscrew the stock intake, which looks rectangular for both sides. You just snap a cone pref. (Jim Wolf Tech. Intake) into the T elbow right after the MAF. If you but a JWT intake for about $100, you should get instructions. Installation should be about 30min.
It is easy dig right in just be careful with electrical connectors to the air flow meter. Remove and save the old parts.
