will a cold air intake make u lose hp

[cameron (240sx)]

any help

[simmode1]

Nope. Won't make you gain any either... Nothing noticeable anyways.

[E7-S14]

eh some say helps throttle responsesome butt dynos say gains in hp. and some have proven dyno gains.

gains are minimal at best.

[OutToWinPAHC]

Why do you ask? Did you just install one and now running sluggish? If so it could be a MAF or vacuum line, or just a botched install

[sebazztard]

i honestly belive they are pretty uselss, unless you are going full intake, header, catback, full exhaust system. it might "look" better than stock, if thats what you are going for, but i would rather spend the money on beer for a month.

[pj]

you will get a couple hp out of it, but its not really worth the money unless your going to port out the manifold and head, get a larger throttlebody and change the ecu tune.do all that and heck yes you will feel a diff, otherwise gains'll be very minimal.

but i would rather spend the money on beer for a month.

lol

[Stripes]

To me they are just something to spice up the engine bay a little. If you do it you should just make your own. Then not only will you save money, but you can make it however you want it, and you can say you made it yourself.

I saw a dyno result in a Super Street a few years back where they lost horsepower with a cold air intake on a car.

I don't remember the exact situation, but they were putting parts on one at a time to gauge performance increases.

But, I have had an ebay cold air intake on an otherwise stock ka and it didn't feel like it lost or gained any power, it just got louder.

So does the same go for a short ram intake? Whats the difference?

[SirSilvia]

I would think calling it a "cold air intake" is a bit retarded IMO, either way you're still pulling it across the radiator making it warmer. But wouldn't the plastic stock one keep the cool air from the air box cool even when running across the rad?Going to autozone or where ever and buying that ridiculous one for a couple hundred is just... As for performance gains, if you REALLY want one, just get an ebay one. need to make sure it has vacuum bungs on it as well.

So does the same go for a short ram intake? Whats the difference?

A short ram intake I'm guessing puts the pipe and cone filter or whatever it comes with, on the same side as the intake itself. should include a significantly shorter tube and the filter can be put where the battery sits. (which would obviously require a battery relocation to the trunk)This would help get more cold air to the intake. but is it really needed?

I remember when I first came here I saw this little thing on each page.Kinda like the geeky girl at the prom.It kinda sat over in the corner by itself, all alone.Everyone knew about it but no one seemed to ask it anything...Even after a number of makeovers it still get ignored...............ITS THE EFFIN SEARCH BUTTON!

aight I'm done, I'm going to bed

A cold air intake probably wouldn't rob much HP, but the short rams that everyone get for these may rob a slight amount of HP because your really not pulling any cooler air.

I would think the plastic oem intake would be better than a metal one. The metal would hold in heat more efficiently than the plastic, depending on the thickness of the plastic. I figure since K&N charge $300 for a stupid intake, I could buy a nice used turbo for that amount. I dont know about you but I would rather make steps in the KA-T direction than an intake.

IF it's a true CAI that goes under the fender and picks up air from under the car then it MAY produce some sort of value, although WAI (the ones that just replace the stock air box with a cone filter) provide nothing. A Short RAM on the other hand, is cheaper, nicer and actually gets cool air if done right. Since already being on the COLD side of the car (intake). When installed the battery gets replaced to the trunk. Then the Battery tray gets cut out. You can now install a small metal C from lower front bumper up to old battery tray area. Now when driving you have a nice cold area that your intake is getting air from. This provides the Short RAM with the same abilities of the CAI.

FYI - Metal (Aluminum) dissipates hot air faster than plastic.....a lot faster. Especially when air is running through it. Even better when cold air is running through it.

just cut open your stock air box....feel like you just gain 500 WHP

[Ghast]

I believe that cold air intakes work to an extent.

On my set up for my daily i use a short ram intake and a hood that has an intake duct right next to it. Surprisingly enough i DID notice a difference (Not omg super 400 HP, but when you know your car. You can tell something is changed) It also has an open vent for letting out hot air which sits right above the engine. I don't really like it when it rains but at idle you can really tell it is letting the heat out. I am not to keen on the idea of having to make the air travel further IE: CAI, nor do i like the idea of it being down there closer to the elements, tho it may not flood in your area.

I would say i cold air intake is great for dry weather. but i guess it all depends on where it is mounted at. A Cold air intake would also avoid you needing any type of vented hood to source air to the intake. Another thing is the water bypass sponge thing that some of them come with, i don't like that. it would seem to me that it is useless in dry weather and just be more restrictive.

Sorry to have typed so much.

Have a good wednesday everyone!

Im retarded, I was not thinking aluminum at the time. Seeing as how every cold air intake is made from some kind aluminum you would be right.

[brizanden]

it works for a bit of gain like 1-5 hp(with full aftermarket exhaust). But if you can reset your ecu and drive it really hard it will learn to suck in more air. I guess ecus when new learn the driving habit of the car and try to maximize the mpg. If you drive it hard once its reset it will learn to want more air so in effect the stock air box can do just as well as MOST cold air intakes. I know i have an article on this somewhere....

[ThuG LyFe]

bottom line is nissan knew what they were doing when they designed the stock air box and getting any kind of stupid intake is not worth it unless you just want a little bit of a louder sound.

just get a k&n drop in filter and call it a day.
