Possibilities for a 90'

Just curious, do CAI's exsist for a 1990? I saw injen's short ram that has a tag along attachment for 100 bucks to turn it into a CAI.... But would i have to move my battery or something? And are there other CAI's for a 1990 240sx? and i say CAI - Cold Air Intake, i've seen some previous posts where a guy asked for a CAI and ano. guy came back with a couple short rams...

yea they exist. it would attach to the part where the air filter would be and relocate it near the wheel of the driver side. The battery is on the passenger side and the intake wraps around the fan going to the driver side. It is a easy bolt on and it just makes the intake longer so it can suck air out of the engine bay at a colder place.
