I'm sorry, I don't know much about 944s beyond my NA. If the cone setup could be put where the airbox is, then everything's good. I was just saying that I had no gains with my cone so I went back to the box.

I don't think anyone has shown real gains with a cone in our cars unless other work was done additionally. Porsche really worked their magic on these cars. I have recent GTI and it is SOOOO easy to get bolt-on power that makes a difference. It just doesn't work like that on the S2. Porsche did their homework.

My $0.42 as a 944S2 owner:
1. Cone filters may make 'better' sound, but they most likely won't result in any HP gains, as stated above.
2. The 944S2 stock filter has a 'ram air' effect. Changing the location of the filter (necessary with a cone-type filter) will negate that effect.
3. I don't like K&N filters - from what I've seen and heard on car and motorcycle folks, while they may allow more airflow, they also allow more dirt particles into the motor. More air = GOOD. More dirt = BAD.
Keeping the air filter setup stock is the best bet going for the 944S2, IMHO.

I'm not implying that VW did NOT do their homework. In fact the 20thAE GTI was rated the most correct GTI since the original by all who reviewed it. It's fun, responsive, effecient, and has tremendous handling and brakes.
However, Porsche has different standards. We all know the evolution history of the 44 so i don't need to repeat it. Even the 1991 S2 944 had functional changes from the 1990 S2. The VW on the other hand did not really change that much in its 6 year run or however long its been. There was no need. No pressure to perform. Then again the S2 was $53,000 and the GTI is $17,000. There is a difference.
I shouldn't really compare cause my GTI is turbo, so little things do make a difference. A chip adds 50hp dynoed. A chip in my S2 added maybe 5 hp ? Even Porsche wasn't getting past 225 on the S2 with their sport edition mods in the UK. Basically, i can drop $2000 in engine mods to my GTI and put it over 250hp from 180. Sadly i don't exagerate. $2000 on my S2 engine...well there really aint much to do except change my belts maybe! Better spent on the suspension!

One of the reasons there isn't much power gains to be had in a 944S2 is because the 944S2 motor is a relatively early version of a 4-valve per cylinder head. As such, many preceive it as a fragile unit and often shy away from suppling aftermarket 'go fast' goodies for it. (Same applies to the 944S and 968, BTW).
Another reason it is difficult to squeeze out more power from the motor is that Porsche already did that. Given the technology of the day, they extracted alot of power from that not-so-little 4-banger. Even the Firestone Firehawk S2's didn't have that much more power!

You will not see any gains with the intake unless you change the rubber hose between the MAF and Throttle Body to see maximum gains. The stock intake box is designed for long service chaing intervals due to the placement in the headerpanel. Also the whole system needs to be enlarged but the TB is not really a problem untill some other larger problems are taken changed.

I can only imagine what that cone set-up would do to HP in a cramped S2 engine compartment as it draws broiling intake air from around the the engine and through the radiator.

Actually Clark, the airbox, or cone for the S2 is outside of the engine compartment in the bumper. It doesn't draw air from the engine bay or the radiator area. It gets air forced on it directly from outside. The upper front slits between the turn signals are basically 2 inches from the airfilter. Air going into those openings hit the filter head on. Especially a cone.
Some people would call this a "Cold Air Intake" or "Ram Air" in some cases. Whatever its called, you can't get much fresher air than that!

Oh! I didn't even notice that pic was incorrect! I thought that was another style car or 968! OOPS! Wow, someone converted it! I would think it makes more sense to put the cone where the stock box anyways! Not bring it back inside!
My bad Clark!
My bad Clark!
