Cold air intake

[kenbui02860]

I have a 944s and looking for a cold air intake, any suggestions on a good brand would be great.

[pearldrum]

A "cold air intake" won't do anything performance-wise for your car. I bought a cone filter and adapter on ebay for like $15. Although it did nothing for performance (which is what I expected) it made my engine sound alot better. I think it was $15 well spent...I wouldn't spend anymore though.

Vibrant makes seperate parts so you can adjust the positioning for the intake . Which will help adjust the air flow positioning to add performance to the car. I know some companies who make the intake but the cone is located behind the radiator. There is no air flow there.

If there was no air flow behind the rad, then there would be no air flow through the rad (it would have no place to go) so your car would overheat. I think what you meant to say is that the air behind the rad is warmer air so you get less volumetric efficiency.

[kenbui02860]

Sorry that was what i meant the air flow is just weaker there than where if I can adjust my intake to recieve more air .I pretty sure this would work better and sound better

My understanding is there's an aftermarket cold air intake set-up available for the 944S that put a cone style filter under the header panel just above the bumper.

This is the longest I have seen one of these threads go without getting flamed....

I am impressed as well TNT, so in my opinion providing cold air through means of rerouting the intake is not a good idea on an NA 944, This takes you out of stock class in autocross, where we already get our butts kicked, and it doesn't help your performance at all. As pearldrum stated at the start, all a cold air/cone filter will do it make a different sound. I like the sound but i prefer sticking with my stock airbox, because it actually does a damn good job. If you really NEED to make a cold air intake check out lindsayracing's behind the headlight box, you'll have to make your own, because that one is for a turbo. And this will force you to cut that bracket off the back off your driver side headlight. So really its up to your, but theres all the option, which I'm sure have all been covered in the past posts on this subject. Use the search please.

the intake location of the air stream is on the cold side on the various 944 cars. Porsche has gone to considerable length to do so. Look at the air path on any 944 and you'll see the extremes that the engineers went to to avoid pulling air from the engine compartment. Some are ducted all the way to the driver side front wheel well. The S2 is routed ahead of the radiator.

Because a 4 cylinder motor really doesn't pull down all that much CFM, the air filter and intake assembly is really quite easy to oversize. Rest assured, the Porsche designed air intake system is no less effective than their cylinder head and injection system because the same engineers designed it.

The fallacy of a cone filter is this. One, they don't really offer any more surface area for filtration, they actually offer much less because the stock filter is pleated. Do the math, you'll be quite surprised. Two, the cone is located in the motor compartment (most of them are) and as some have pointed out, this will draw hot air coming off the radiator, hot air being emitted from that big hunk of aluminum called the motor, and the headers. Hot air will hamper performance and a cone will probably run slower than the stock filter.

You know my positiion on the K&N system (expensive junk that will oil down your injectiion sensor system, do nothing for performance, costs money, and admits more dirt into your motor) so save your money and buy a premium stock type filter.

In short, the air intake system on a Porsche is a good one.

Happy 944 motoring.

...p awesome, you layed it down my friend

[UconnTim97]

...P beat me too it...lol

Same old tired arguments - don't change anything cause the engineers knew better. Not everyone is a purist, and there's nothing wrong with making your ride your own. Besides that pleat thing is ridiculous.

you can change stuff, but just bolting on a snorkel and a cone isn't going to make your car any faster. If you want more airflow, and more importantly a real power improvement, you're going to have to build some kind of heat shield to ensure that the intake is drawing cold air... just like the stock airbox already does.

OK guys. Figured it out. I went to a porsche performance guy around the way. He said my best option to customise my own intake and build dual air intake. I don't know how to lay it out but i do know how to make it. Thanks for all the sugestions.

[TNT25169]

I'm pretty sure he's pulling your chain. Getting air into a 944 is not really a restriction on the engine. The engine gets as much air as it needs and you might just be wasting your time to fabricate something like that. The hp gains will be minimal, 2 hp at the wheels maybe. You might want to look into a cam. I have heard that makes a good difference. Or look into one of FRwilks chips. He posts here on this board and rumor has it that his chips are pretty good. Just my 2 cents...

[Sabyre]

AMEN ..P!

[TNT25169]

I can't believe no one said that before me.

[..P]

Well guys, does anyone have a ladder, so I can get down off this soapbox?

There's always going to be one guy out there who wants to booger up a perfectly good car, and who is willing to argue about it, tee hee, such is life I guess.

Getting more hp from a 944 is cool and all. You just need to know what your getting into. There's a lot more to the car than just the engine. I use my car for racing and summer fun and you could say I'm a little rough on it but it's still my baby and I want it to perform to it's peak. I don't care that the little badge on the front says Porsche, it handles like a dream, it's my car, and I am going to make it the best it can be. I just know to take the advice of the elders....

Well, I'll definitely be going with an aftermarket (K&N) setup with this engine rebuild I'm working on.

Lots of people say the cones add power if routed correctly...an equal number say they don't do a darn thing.

But in the end...no opinion is as accurate as a dyno. That's the only way to know for sure. Run a baseline, take 15 mins and bolt up the cone, then run her again.

Unfortunately, I will be adding a number of minor modifications at the same time so I won't be able to dyno after each addition (I just don't feel like redlining the car 5 times in a row).

I don't know, maybe I will...time will tell. I'm a long way from being finished. But I was planning on adding a chip, intake, exhaust, and ignition system to help pep her up a little.

At the very least, I'll do a before/after for the chip+intake. If I can do 1 at a time, I will...but unless I can do it all in one day, the results could differ due to a change in the weather. It would be easier to do everything at once, but then that would beg the quesiton...which additions yielded the largest gains?

But I digress. At the very least, the (K&N) gauze filter is certainly less restrictive than the (OE) paper filter. The original engineers were not building the stock motor for sheer horsepower...they had to build the motor with longetivity and ignorant owners who would forget to change air filters for 60,000 miles in mind. I've yet to see a race car with an AutoZone OEM paper filter because it's "just as good as a K&N", for whatever that's worth.

But if you're in doubt, hit the dyno. It's the only way to know for sure.
