air intake question

I've been trying to figure out if I should change my air intake from stock box with a K&N to something more "agressive" First I think my car has the "mass airflow" system and not the "speed density" not quite sure. :shrug: Need help with that. :( Once I figure that out, what would be the best bolt on replacement for the best price :shrug: ?
 
Look for the mass air sensor, it's between the filter box and throttle body. I have a Mac intake, worked well so far. What year is your car? What other mods are on the car?
 
Many people will tell you that the stock airbox + K&N is just as good as an aftermarket CAI. It draws air in from the inner fender area just as a CAI does, and the plastic construction insulates heat better than the metal most CAI systems are made out of. Personally I would spend my money elsewhere.
