cold air intakr for my 83 944?

[Trevorlw]

I live in cali. So I HAVE to have a Carb No.

Don't do it, you will lose some hp. Stock box is better and it draws in cold air from the fender area.

Stock Box doesn't draw air from any fender. Sawd off. Broken.
Stock box has a Hole the size of a Golf Ball on the bottom. Tell me how it wouldn't improve it?
Any Filter isn't gonna improve it. NORE disprove it.
Filter is just a Damn filter

[CHICKS]

Like pops said, there is nothing better than the stock air box. If yours is a piece of ****, then start looking for a used one. You will gain nothing from a cai.

Then mend it, dear Trevor, dear Trevor, dear Trevor

replace it with a good stock airbox from a wrecker. make sure its got the snorkel and the seal to go into the fender.

the stock airbox is better than a pod filter. period. you may save weight with a pod filter but thats about it. you will get heatsoak with the pod filter without sealing a new box around it and ducting air to it but then the stock airbox and filter has more surface area than a pod filter so why reinvent the wheel?

get a k&n panel filter that fits the stock airbox if thats the kind of thing that gives you jollies.

it makes me crazy when people try to tell you that the stock airbox works better than a cold air intake. it doesn't. this does however assume that you actually have a cold air intake, and not just some cone filter stuck somewhere.

a good cold air intake will give you about 5% more power than the stock airbox of just about any car. there are very few that cannot be improved upon. it will have a cold source of air, and a direct route to the intake. the connecting pipe will be smooth and without obstruction (no ribs etc). the filter will have at least as much surface area as stock. preferably it will have a box around it to maintain a high pressure zone

done right, you can get more power. the tradeoff is usually that you gain more noise.

that being said, i don't know if anybody has gone to the trouble of getting a CARB certification for anything. i'm also not so sure you need one.

So basically, you have a cold air intake stock. Ditto on the K&N What is the CARB number for?

Solves the problem and most likely cheaper then have to get original and continue with the big blocky Box. Lol

In California, any modification from stock air intake/box/filter size/etc. You HAVE to by law have a CARB No. for Smog.

California Air Resource Board (CARB) # is so when you go to smog it in our lovely state (that received $$$$$$ for this number to put on the sticker) saying it is legal to use on emission controlled car in California with the states ble$$ing....

What does CARB compliant mean - Ask Community

Trevorlw if you need a stock air box I might have one laying around, I can check this weekend for you.

Yep - the stock 944NA air-box is a very good design: large filter, bell-inlets, plenty of volume on each side of the filter, decent diameter snorkel, and pulls (cold) air from the fender well.

Not a single HP or TQ from swapping to a K&N. I dyno'ed back-to-back a used stock filter, K&N, and new stock filter. They were all the same - no measurable difference between any of them.

Not this time Flash. I've had the 944NA airbox both on my flowbench, and dyno-tested back-to-back. I couldn't find a single HP from anything I did with the airbox (including removing it completely).
For a 2.5L Non-turbo, it is the best performing solution.

Any Intake System unless you add a tornado/Turbo/Charger. It will not make any damn difference.
Filter is a Filter. Like a Oil Filter. I highly doubt an oil filter would add HP.

Haha I know what CARB is (I live here) but I meant why you would need it, Smog shops here must just not care...

Smog shops wont pass it and charge you smog and require you to get it fixed and pay again to smog it properly.

I know RA :-) but some people like the extra noise though. And the k&n stickers.

[curtisr]

The first clue that the factory snorkel set-up is a good one came to me when I asked for a K & N cold-air system at my favourite auto parts store. They told me that K & N doesn't make one for the 924s, anyways. They do, of course, make a filter to fit the box. [Which, by the way, I found to not fit my 928's air box very well: I had to twist the straps to take up the slack (as it were).]

[flash968]

i'm quite sure i could find power in a cold air intake. in 30 years of doing this, i have never seen a car that could not benefit from one. it's very hard to show it on a dyno, and you have to use an eddy current dyno. you can't use a standard dynojet. you also need a HUGE fan that can make 100mph wind.

due to german sound restrictions, they have to build their airboxes with a that in mind. unfortunately they always cost power.

a manometer will show you where the OEM airbox falls down. it's not hard to find the restrictions. some of them can even be calculated.

i see why people have a hard time with the OEM airbox, but i also see how it can be done, and i am sure it will work. the problem is that you're going to spend more money that it's probably worth to get the amount of power you would get. i just can't see somebody spending $200+ to get 5hp.
