Actually, K&N filter... I took the K&N filter and took off the excess oil by carefully blowing air pressure into the K&N filter. The reason for going with the K&N is because I used the filter on my previous 964 and 993 P-cars. Either way both are great filters!

I am not affiliated with the K&N filter. PCA has determined that the K&N filter is not to be blame for the (MAS) Mass Air Sensor issues. Simply, the MAS has failed due to defect which has no relationship with the air filter. However, having excess oil on the filter before install is not a smart move in my humble opinion (common sense). Below is the technical response from one of the best P-car master tech's in the United States.
If you put on too much oil you might coat the Air Mass Sensor and according to K and N.

Will a K&N filter cause my vehicle’s mass air sensor to fail?
At this time, K&N is unaware of any evidence that K&N air filter oil from a K&N air filter can damage or cause the malfunction of a MAF sensor, regardless of the make of the vehicle involved. K&N takes seriously any claim that one of its products is incompatible with its designated application or can damage or cause the malfunction of any automotive component. Such claims are thoroughly investigated and, when appropriate, testing is undertaken to determine their merit. In the case of MAF sensors, ongoing tests have shown that contamination from K&N air filter oil has not caused any failures or malfunctions of the MAF sensors in the test vehicles. K&N is aware that MAF sensors can become contaminated for a variety of reasons, unrelated to a K&N air filter (such as backfiring, blowby, leaking airbox or leaking intake duct) and that various methods have been used by some service departments and repair shops to clean a dirty or contaminated MAF sensor, such as spraying with an appropriate cleaner. K&N has not completed any tests as to the efficacy of such a process and, therefore, does not officially endorse or recommend any cleaning process. However, if given the choice of either replacing a MAF sensor or cleaning it, K&N recommends that the consumer ask his or her automotive dealer to attempt cleaning, before replacement. It should be noted that the presence of contamination does not mean the contamination was the cause of the MAF sensor failure. Sensors can fail for electrical or mechanical reasons, unrelated to any visible contamination.
I have replaced numerous air mass sensors on vehicles that have a stock filter, so I don't think the filter oil will cause a problem. Will you get 20 HP, I doubt it. They claim HP gains on numerous cars yet when you go to the products page for Porsche there are no dyno numbers.
It's up to you whether to spend the money for the filter or not...
