My post was the second post, so there wasn’t much to review. He didn’t indicate the model, I didn’t see it, so I asked — especially since he said he has multiple “cars” in the post. I own 3 Porsches; nobody has any way of knowing which car I’m talking about based on a picture of a used air filter or a single model name in my signature. Sorry I asked. Will unsubscribe now.
Interesting…
why no BMC? a little more washing and oiling I figure you’d be ahead than the obvious loss of airflow you must have been experiencing with those filters in that state.
10 track days will do that. Remember your engine wear isn't about miles, it about how many revolutions it has made. Running 10 track days at a consistent 5000-8000 rpm sucks a lot of fuel and a lot of corresponding air. When you are on track with other cars that are spewing a ton of exhaust, it will also get sucked in. Just saying. Gotta pay to play!!
On a different, but somewhat related note, this is the same logic for engine break-in debates. An engine run at 4000 rpms will require 1500 miles for the same break-in as one run at 3000 rpm for 2000 miles. That's why the whole idea that break-in should be based on miles makes no scientific sense.

You don't break in an engine at constant RPM - have to keep varying the RPM/load during break-in.
I prefer gradually higher RPMs during break-in, which makes sense as most of the initial wear-in will occur very early on. Going from 4000 rpm limit at 1990 miles to redline at 2001 miles, what's the difference really?

Is the OE maintenance interval every 40k/4 years? Yours look properly dirty! I wish these were easily accessible for visual inspection - a downside of a mid-engine config.
I clean my intake filter on my supercharged Audi probably every 2 years (~8k miles) and its never as dirty as yours... guessing the side intakes ingest more thrown up debris vs a conventional front engine intake?
Yep, I have had exactly the same thing with mine. The log book maintenance interval is completely inappropriate if you track your car. They need to be replaced every 5000km.
~5000 miles on my first set of BMC filters. Absolutely no reason that I can think of to not use BMC’s, especially since most RS models ship with these as OEM.
Now that I have two sets, swap out every 5K miles, or sooner pending usage. Clean one set, replace the other, rinse and repeat.
The image shows the new filer and used - keep in mind, that my car saw a decent amount of daily driving, and Im not talking only sunny days. Replaced about two weeks ago.
Same reason I didn't do BMC filters. I'd love to see an oil analysis comparing silica levels with the standard filters to those with the BMC filters over the same mileage/use case. Other oiled cotton gauze air filter tests show evidence of elevated silica in the oil from less than adequate filtration allowing dirt into the engine.
Do the RS models that include BMC filters as OEM have the same induction system as low on the vehicle? Perhaps the 4RS intakes in the rear window area get cleaner airflow that doesn't pick up as much dust and debris as the standard GT4 ducts.

Mind those air filters
