'86 944 turbo

Has anyone installed a K&N filter for the 944 turbo. Did it make any performance gains? Or is there a different air filter for these cars? Let me know.

Mine came with one, it works good as far as I can tell, many feel good ol' paper filters-better. I believe the main concern was what happens when the K&N isn't oiled well enough to trap particles, without the oil there is no filter.

I'll let you know Thursday night (or Wednesday if the UPS guy is fast).

I can hear the diff. more than feel it.

I installed the new K&N X-Stream filter. I noticed a performance increase as soon as I changed to the cone filter versus the air box. I started spinning the tires in second when getting on the throttle right after I installed it. <img border="0" alt="[burnout]" title="" src="graemlins/burnout.gif" /> I do have a testpipe, so I guess the cone really helps the turbo breath. I noticed a performance increase after adding the testpipe also. It sounds great too.

Hmm...I read on here and a few other sites that the cones don't help as much as a good filter in the stock air box. People were attributing it to the intake being right behind the intercooler and lacking adequate airflow.
I'll be content with the K&N filter, since the turbo is pretty damn fast stock, but I'd be interested in seeing some dyno comparisons.

I have a K & N for the stock air box that I'll sell for 15.00 plus shipping, The car it was in was totaled and now the filter is sitting in my garage...

Dave E can you send me some pics of the filter to my email leosagos71@hotmail.com If its in good condition i'll buy it.

A number of threads have discussed this issue; I can imagine that a test pipe coupled with the KN would have a far greater impact than just the KN. FOr me, it sounds a bit "growlier" and perhaps there is a bit of seat of the pants difference, but that's probably just me justifying my purchase...

Search for 'cone filter stock air box' in this forum and read for yourself.
I don't know if the argument is correct, however, which is why I would like to see dyno runs of the same car with both options. Preferably in some sort of wind tunnel that more accurately simulates driving, cuz the cone behind the intercooler is going to benefit more from high speed air flow.

Since there are people who say each is the better option, I'll stick with the cheap K&N filter until I have some concrete evidence.
But if it turns out the cone is better, I'll get one.

I have the MSDS cone filter. I don't think i can feel or hear a difference. But there is one thing I like about it as I am preparing to do some work: accessibility- one or two screws later and my filter is off. Taking off the OEM air filter housing was a chore!

I also have a K&N filter I would like to sell if anyone is interested. It is for the stock airbox and is in like new condition. I decided to go back to a paper filter based on convinience. I race motocross and I clean enough filters with that.

ag951 it's this simple. I had a K&N filter in the stock air box for a long time, and drove my car with it in, i.e. hands on experience. Then I switched to a K&N cone filter. Read all you want. I don't need to read anything I've already done it, and I know what it did to my car. I noticed as in I drove the car lots before and after. I don't drive any differently now, and I don't need to go to a dyno to tell me the car just simply runs better and has more power. I'm not going to go do dyno runs just because I put a cone filter on the car. I do have a testpipe, like I said, and I do believe this is a key part to it working this well. I did the conversion for $13, cone filter included. The adapter I modified came with a generic cone filter. I installed it with that filter while I was waiting on my K&N cone to come in. There was a difference right away. When the K&N came in and I put it on I didn't notice a real difference between the generic and K&N cone filters, I just trust the K&N more. So for $13 you can see for yourself what it will do to your car. Then change to a K&N cone if you want.

For $13 I'll test it out. Where did you get it? And if I ever go get a dyno, I'll share my paper filter, K&N square, cone, and K&N cone.
