Just installed K&N intake.............
Just installed K&N intake.............
Wow. What a job.
Total time --- about 5+ hours.
(I though I remember somebody saying it was an hour job. I suppose that could be true, just like it is possible to beat Tiger Woods in a round of golf.)
The K&N instructions are subject to interpretation as they tried to get away with only one exploded drawing, and the pictures are poor so you have to pay attention. Much of my time was spent being careful of not using the wrong part or damaging anything.
One of the hose clamps is way too small to fit around the intake tube and a positioning guide or holder, so you will have to use one of your existing clamps taken off of the origninal air box assembly.
You will also have a lot of fun trying to take off the mass air flow sensor. Pay attention to the instructions because a bit later in the install you have to take the rubber boot off and spin it 180 degrees to get the sensor to face the correct way.
Another snag that required a run to the hardware store was get additional hardware to help secure the Porsche factory plastic intake. With following the instructions, the intake kind of leans off to the side and will not line up with the hole in the rear deck lid. So I picked up a small "L" bracket, screws, washers, and a nut to keep it in position. Not that big of a deal; just time consuming. Definitely should be supplied.
The test ride:
There is no doubt that the car is more responsive and has more *****. Not much going on under 3K RPM, but hit it after that and things start to happen fast. You'll also notice a more pronounced howl under hard acceleration.
Overall, it was $250 well spent. Probably the best HP pop for the $.
My back is sore from bending over the engine compartment all day, but then again so is my face from smiling.

Congrats!
LOL- yeah I had a tough time with the metal airbox assembly, the instructions suck.
Took me 2 hours... are you sure you weren;t taking a lot of beer breaks in between??

The K&N runs about $275
Evoms runs about $600
Fit and finish/design, I like the EVOMS, it's a little nicer, but as far as performance, I don't think you will see much difference between the two. I'm probably going to go with the K&N because I don't feel that the EVOMS is worth the extra $325.

i blew 4 mafs total (2 each) using both systems... not worth the headache in my opinion... sound great though
and its sounds like this is a my99-2001 problem only as it seeems to be more prevalent in these models

Same problem here...1 went thru 2 MAFS before I put the stock intake back on. I tried drying the oil for the second MAF and still blew it after 3 months. Have to admit...i like the sound and power. I am on my 3rd MAF...over a year and still good. Good luck.
It's a touchy subject, seems to be isolated incidents, a lot of good reviews and thousands of miles w/o an issue, but there are quite a few people who have blown their MAFs.
i dont think its the oil...
with the k&n i had hi temp readings on the MAF... and basically they were electrically not functioning.
then with the EVO i had out of range errors...again electrically not functioning.
if it was oil... then you could clean it off...i think it is more to due with a crappy maf design, and thats why they changed it for later 996's

Hmm, can you elaborate? I don't see how one filter gets less dirty than another one when used under same conditions. KN filter will provide same filtration whether round or flat.
