No it won't......not on this motor. The stock intake is a CAI. The air source is outside the engine bay. The tube is straight and of the same diameter as the throttle body. it is constructed of a dense plastic that won't conduct heat like a metal tube will. The cross-sectional area of the air filter, likewise, is set up completely perpendicular to the airflow to allow for the greatest cross-sectional area, and therefore, the least resistance to air flow.

Aftermarket CAI's work in some applications to produce even up to 10-12hp gains, but not on a Z. If you claim that they are better, please indicate to me how their design is superior to stock, explain the physics, and I'll listen. Also, "ram air" in a street vehicle is a joke. Tell me how much of an increase in intake air pressure you will get at 100mph? How about 200mph? These are all marketing gimmicks. Do it as a mod for the sake of a mod, but don't kid yourself into thinking you are getting any more power. As I also said, with a combination of ALL other breathing mods, an aftermarket filter may get you an extra 1-2hp.

There is a special water proof bag sold to cover the filter.

So I take it this is another Marketing Gimmick?

this is so true, I was going to buy the Nismo CAI but it was too much money and too much of a hastle to clean (bumper)

I have the JWT and its great - whistle sound and roar of the engine

Did you read what was written at the top of the dyno graph? Let's see......a dyno plot to promote the Injen intake by Injen. Has any independent testing consistently reproduced this data. My questions:

What other engine mods were on the car?

Same car or different cars?

Air temp between tests?

Humidity between tests?

Why a 7 hour difference in time on the dyno?

Tire width on the test cars-same or different if rolling dyno.

Tire brand on the test cars-same or different if rolling dyno.

How many other dyno runs did they do showing no gain before they posted this one showing some gain.

Believe me, I have a strong science and research background and to prove this kind of data consistently, you would have to test about 40-50 otherwise identical cars, stock vs. intake alone, in exactly similar test conditions.
The normal variation in stock engines alone will be on the magnitude of 10hp. Try to convince yourself all you want, but the independent, objective, randomized, statistically significant data just isn't there.

Also, what about the torque? Horsepower is just a calculated number from torque and rpm. Lower overall torque, but at a higher rpm will yield higher hp, but that doesn't mean you'll have a faster car.

Yet another dyno plot from, guess who, the manufacturer!!!!! You guys really want to believe that gaining power is so easy. Sorry. All of the power listed in your sig comes from your test pipes. Guaranteed.

Well than look at my dyno graph doofus! Granted there are other mods I asure you the Popcharger helped.

I have the Injen sp 1986 and will say I did it as a mod more so for bling factor, and sound .I had the Nismo exhaust with the stock airbox and K&N drop in filter then went with the Injen and noticed some improvement over stock. Im sure it's not going to win any dollar for HP award but I like it.

my 2 cents

Zhane

I agree that the manufacturer is going to find anyway they can to modify/change whatever they can to produce better #'s and yes every car is different etc etc.... and I definitely don't think your gaining 10-15hp (Injen) with Just a CAI however to say you get no gains at all IMO is rediculous.... but hey i'm no rocket scientist so what do i know.

I have the Nismo CAI. I love it. The car defintley felt like it had more pick up, up top. I couldn't really feel a difference until I got around 4500 rpm.

Speedracer

Your dyno numbers don't show an independent test of the Pop Charger unless I missed something. Also......watch it with the "doofus". You have no clue who you are talking to, do you. Your pulley is getting you a few hp, but it's your plenum mod and test pipes that are gaining you everything else.

Once again, you fail to address the issue of proper testing.

Run your car 10 times with all your other mods and a stock intake. Then run it ten times with the Pop filter and all your other mods under IDENTICAL test conditions. Then look at the data. You present your dyno data but fail to account for any of the huge number of variables that go into the numbers.

How but you prove that it doesn't produce gains? And as far as the Stop being an internet thug. Once you prove that it doesn't produce gains than I might think you have some type of automovtive knowledge.

pecora55

Internet thug...love it...

Speedracer

Automotive knowledge?! I'm trying to give you objective information, and all you can do is make crack comments. So....how's this:

I've owned and modded 5 cars with up to 600hp. I have two degrees from Harvard in Medicine and Physics. I know more about cars than you do about life.

Sorry for the arrogance, but you were asking for it. Game over as far as I'm concerned.

Are you sure you're going to GAIN at all with CAI?
