Hmm I am not quite sure what to make of this as I have custom built draft and positive ram air systems on many cars and not run into that problem. I would check your exhaust system and general engine health(plugs, etc). Generally the computer adds more fuel due to the reading from the MAF sensor, and the ambient air temp sensor, and if your engine is running too rich I would have to say it is not because of 15% more air flow. I would dare speculate that your car is merely surviving as it is. Then when you added the K&N filter you only magnified the problem. I would almost have to say that the culprit is more than likely what you are thinking, lack of fuel. To get deeper one would need more info, (old Filter, dirty plugs, dirty inj.'s) I would assume that in the P's you might run into a dirty MAF sensor due to humidity and dust, but one would think that would cause the sensor to read less air flow not more, but you can never rule out Murphy!HTH

Also I have read that others have had issues with the filter oil tainting the MAF Sensor. GL

Same thing with my 99 996. K&N now in a box in the garage. Liked the perception of more air..not sure about the sound... but really didnt like the CEL and stumbling idle and high RPM issues. Know anyone who want to buy mine?

Weird!

I just installed a K&N type 63 on my 2003 C2 and it seems awesome so far. Great sound, improved throttle response, and no issues whatsoever. Idles the same, and pulls hard in the high rpms. you can really hear the Variocam switchover now!

Had mine installed for about 10K miles and never had a problem... make sure you followed the instructions accurately ( MAF positioned the correct way, battery unplugged to relearn air flow )... same experience as kitw.. sounds great!

Only drawback is the exposed air filter... stay out of automatic car washes or you will drown the engine!

I really wonder what these things do. It seems to me that they pull in a lot of hot air as oppsed to the stock system. Not sure on the K&N, but others I have seen seem to.
