I knew the cold air sucked in cold air and ram air was forced air (I'm generally smart about cars.. I swear).... but, as far as the intakes themselves go... I don't know the difference... cuz, I've seen "cold air intakes" go in the same place as "ram air intakes"... maybe people just name it wrong.. I don't know... but, which works better on a 240SX (SR20DET)?
ok, ram air intakes don't force air, unless they're setup to directly take in air from the front of the car. s13/s14 "ram air" intakes aren't "ram air" by any means.
injen's CAI for the s13/s14 is a prime example of a CAI that is technically a ram air intake since the filter sits right in front of the front tire on the driver side.
however, it's also DUMB. why make a CAI 2-3ft longer than the original intake?
if you want a good intake, you'll have to go custom for it to work better than stock, and not be ridiculously long (not good for high rpm).
relocate your battery to the trunk.
cut a 3-4" hole in your battery tray.
have a muffler shop bend a pipe to run from the throttle body to the hole in the battery tray.
relocate the MAF to the end of the pipe.
throw a cone filter on it.
BAM! custom CAI that's only 1.5 - 2ft long and it improves throttle response and WORKS.
now you just have to shield the filter from hydro-lock. aluminum sheet metal is your friend.
