Filter is a filter really... you can debate this all day but one will make the same power as another.

the injen filter is a K&N (at least they used to be). my only recommendation, if you want to "upgrade" your filter, is to order the K&N FIPK (fuel injection performance kit). the injen filter is alot smaller than the FIPK's. when i say alot, i mean ALOT. the injen filter will fit inside the FIPK's.

i'm not sure about any type of performance gains by changing the filters, but there is definitely a much deeper tone. that, and that huge filter looks very nice under the hood.

Injen made their filter size around the intake. I'd assume that the reduced flow out of the smaller one is better for max hp/torque, intakes are pretty much like exhaust, more than stock is good, but too much is bad. Has to be perfect. Just my .02

that's not true.

there's no such thing as too much intake. you can remove your intake pipe altogether and put a filter on the throttle body and it wouldn't harm performance.

Yes it does. Too much intake lowers low end. Maybe not a lot in these cars but it does. Maybe it's more in trucks, but it does. Did in my nissan truck, and in my friends silverado.

I would think if you are putting in a bigger intake , you should also upgrade your exhaust ... The stock exhaust might prove to be inadequate to handle the higher flows from your intake system

How does the Injen cold air intake raise HP? Because the injen piping is metal but it runs right over the radiator, which could be bad because instead of cold air your getting the hot air. The stock plastic intake probably stays cooler because it doesn't retain the heat as much. Has any one tested the injen cold intake to stock intake, of course the injen probably flows a little better...

Thanks....

A bit of thermal wrap would fix that.. I might wrap mine, i'm not sure though..

Ahhhh, and the reason that AEM is superior to ALL other intakes. I mean...they are really all the same tubes and filters... but the AEM is powder/zinchronium coated to deflect the heat from the radiator. Injen has always claimed to have a K&N "style" filter... I have NEVER seen an Injen filter with K&N stamped on it. IN the ad it clearly says the word "STYLE"... if it really was a K&N it would say, "K&N" filter! I have owned 2 K&N cone filters... and BOTH had the name stamped on the end piece. Injen makes a good product... but I believe AEM is a better choice.

correct me if i'm wrong but the aem intake doesn't have a extension for cold air right??? and the aem doesn't have a red or blue piping right?? it's ok if it doesn't.... i'm trying to choose either getten an aem or an injen.... the aem is cheaper but doesn't have an extension for a cai but the injen does and it cost more..... hmmm wut should i choose????

The AEM comes in red, blue, or grey. They do not have a CAI extension for the 240sx. Injen is more expensive for the short intake.... PLUS it's another $80 to $100 for the CAI extension. Injen only comes in a chrome finish(as far as I know). If you buy the AEM and really want a cold air extension... it's very easy to build one.

I am sorry but if ur really troubled because of hot air in ur intake (and be it AEM or Injen, after a while the piping WILL heat up no matter what the wrapping is), you shoudl do this: relocate battery to trunk, cut a hole in the battery tray big enough for a 3 inch pipe, relocate ur windshield washer tank to where your air resonator is right now (remove resonator before that of course), order a MAF adapter and K&N air filter, make your own custom piping, and put that bad boy together, so you will have a good cold air intake unaffected by the hot hot hot radiator. That's what I'm doing within the next 2 weeks, and as soon as I am done, I will post exact directions and pics.

p.s.: Also cut a hole in the frotnof the bumper, for better air access to filter.

Thats a lot of work for 5 hp. Just get a K&N drop in filter and chop the bottom of your airbox off. Works fine.

Might I add there was some Integra out in Cali running all-motor, 13.6 on a stock airbox.....

wow... your radiator must run REALLY hot for you to go through all that trouble. I can assure you, it doesn't get hot enough to heat up my intake tube to any noticable degree. And, If you've ever held your hand partially over the end of the intake tube while the car is running, you'll see how fast the air flows through there. If you push the throttle down, it will suck your hand into the tube. The air is flowing FAR TOO FAST to be heated up even if the tube temperature does increase. I've driven in stop and go traffic for hours at a time, no air passing the radiator other than the electric fans..... and it never got hot, neither did the intake.
