air intake
are these worth it?
air cleaner kit OR i know it will get some hot air from the engine bay and being after the IC, but will it help the turbo spool easier or any other benefits? I had one on my 944S and it sounded great, don't know if it helped power or not being it was already on the car.

I ran a K&N knockoff cone filter for awhile with the stock AFM before I went to MAF and liked it alot. The hot air was never an issue and in my opinion the car breather much better than the stock air box with a K&N filter in it. I got a universal AFM 3" end and had to fab a bracket to hold the AFM up but I would recommend it. Just my 2 cents.

I just removed my stock airbox because some clown broke the bolt holes and epoxied it back together. Had an SAAS (K&N knockoff) cone filter lying so I just whacked that on. Will report back later after a quick blast.
Okay...blast over with. It feels like it has made a difference to the power. It will spin the wheels easily in first when boost comes on, and then there's the 'flutter' you hear between changes. I like it.

Sometimes you don't have the option NOT to buy one of those setups. The stock air boxes are so damn brittle, they break VERY easily. Mine was broken when I bought the car. But since I was not much of a fan of recycling the hot air from the IC, I ran (or should I say concockted?) a setup that deleted the J-boot, and routed the intake air similar to the way that the MAF setups do. But it was an extremely tite fit for the stock AFM. I actually had to flatten the post IC charge pipe a little bit to make it fit. Butt dyno results were definitely positive, as was throttle response. It wasn't long after that when I actually did make the switch to MAF.

Pic of J-boot delete. Spoolup was definitely quicker, even with the constriction from 3" down to 2.5" @ the elbow, because that is still less of a constriction than the AFM itself.

Any increase in HP from "breathing eaiser" will be lost by drawing in hot engine compartment air. Depending on season, the air in the center of the engine compartment could be as much as 100F hotter than the outside air. And that will destroy any advantage.
The stock airbox draws in cool, outside air. The cooler the air, the more HP produced. That's why Porsche designed the system the way they did. I've seen setups that have a snorkle attachment so you can have the cone filter and still get cool outside air. But that's the only way you can get an advantage from a cone filter.

if you're gonna do it, do it right;
stock airbox + snorkle vs. free intake here's some more info on why cone filters are probably not good for a 944; k&n filters

When I owned my Pantera I was active on a forum there and one of the guys on there posted a results of a test he performed using stock type filters by fram and motorcraft (I'm making up the comparo companies but you get the idea) and K & N - there were four total, one of which was K & N. Bottom line the K & N flowed a lot more particulate matter (dirt) which over time is really bad for your engine, and no significant (measureable) increase in air. For my money if I did use a cone it would not be a K & N, it would be stock type material. Just my 2 cents.

And wouldn't filtering capability be a function of how "generously" one is oiled??

It is my understanding that the K&N type filters need oil to keep particles stuck to the filter itself because the material openings are larger therefore letting in more airflow thus increasing HP. The convertinal filters or dry filters are denser thus make it harder for the engine to suck in the air like the K&N type. Having tried both K&N and conventional the K&N whether K&N brand or a knock off is the way to go. My 2 cents.
