I just bought a 2007 997TT (pics coming soon). And as soon as I get a car I like to go through it and kind of 'make it mine'. I cleared codes, washed her up, and will do spark plugs soon.

I also cleaned the MAF sensors and while doing that took out this BMC filter installed by the PO or some tuner (EVOMS maybe, as this is an EVT775 car).

Take a look at the pics. I will be installing an OEM filter as soon as it arrives. Sometimes aftermarket is good.........but not always.









If you have rough idle, shakey starts, or car isn't running well, you might want to clean the MAF and check your air filter.

**Also for reference, some cars use a #25 Torx Security for the MAF screws, but my car actually had STAR's. Caused me a lot of headache getting those off.

 

Are you worried that the car was driven around like that? Possibility of crap flowing around the filter?

 

I pushed it out of the frame just to show, but the edges had separated. I think it couldn't have been TOO bad, but what else can I really do.

I'll change the oil asap.

 

saw your post on 6speed. I'll definitely keep OEM

 

Compression test it and make sure. You can change plugs/coils at same time to make it worth your while....even though piece of mind that engine is in tip top shape is worth it all on its own.

 

The tech 'cleaned and oiled" my BMC filter once, the car ran like crap immediately. Ended up cleaning the MAF and going back to s OEM filter.

 

As I posted on 6speed.....


Yep..Good call. Tried a BMC once, before I learned they did no good. A lot of money and the rubber turns in to a Gummy Bear after a short time ad it falls apart. Hard to believe!!

Also the fastener you have is call ed a Pentalobe (security version here)...It is like a Torx, but with 5 points instead of 6...When looking for the tool...search "Pentalobe"

Also...OEM is the best intake...No one has any evidence anywhere that any other intake performs any better...I have not seen any anyway and have searched for a long time!

Good luck,

Agreed. Why tuners still recommend Oiled filters baffles me. There is absolutely no performance gain. Stick with the OEM paper filters. And don't buy them from Porsche..

I buy my pollen filters and air filters from this place. Same manufacturer. Great price and super fast delivery..

Not just tuners...Porsche too - I think the 997.1 GT3 and/or GT3RS came with BMC filters as OEM.

 

OEM 7GT2 or 7GT2RS do not have anything that look like that.
Cannot comment on GT3 variants.

 

How often do you change the filter?

 

On second thought I might have been remembering cup cars.

 

Yes all cup cars use them. But they also get engine rebuilds frequently

 

from my 7GT2...GT2RS is same I think I will look. It is a grey open cell foam.

 

eesh just imagine the wear that's gone on inside with that thing. Can't understand why anyone would use one of these on an engine of this expense. Stupid.
