Speaking of MAF sensor failures, I used the stock filters on my old P-car and had that bugger alert ALL THE TIME.
Leading evidence: 'Use stock filters' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check sponsors first' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

But, it's now 2 authorized Porsche dealers/service centers that I have spoken with who recommended BMC usage to me.

Is there anything I should know prior to replacing stock air filter.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Is there anything I should know prior to replacing stock air filter. Looks straight forward. What is number/brand of OEM filter and where can I get.
Thanks in advance

There are a few to choose from such as KN,stock and a B something or other. You can find them all over but check our sponsors first. If all fails go to your local P-car dealer.
Just be careful putting the airbox back in and taking it out. It has two little plastic pegs that slide into holes in the engine bay and they are pretty easy to break off.
Those reusable filter will have no noticible increase in power. The filter is hardly a constraint given its large surface area. Paper will filter better and oily filter may cause MAF sensor failure.
Changing the filter is pretty easy.
Oh not this debate again...
I'll accept that freer-flowing filters may or may not add to performance increases though their usage by racing teams seems to suggest that, matched with a freer-flowing exhaust and chip mods, they do. Then again, at 60-100 mph on the street, will one notice the difference? Who knows? It's a free market, do what you like. But I digress...
These non-paper-based filters do have a bit of oil. Letting them dry a little bit before installation is a good idea. But here's the key: the oil is mixed in an alcohol solution. When the alcohol evaporates, it leaves the oil residue...NOT a viscous glop of blackened motor oil. So, it isn't going anywhere but sticking to the filter. Think of it like hair gel. It comes out of the bottle wet in an alcohol solution, but as the alcohol evaporates (dries), you're left with a hardened styling formula. (Hmm...I'm not sure I like that I even thought about that analogy).
Speaking of MAF sensor failures, I used the stock filters on my old P-car and had that bugger alert ALL THE TIME. It drove me mad. I think it is something that is inherently hyper-sensitive and somewhat unstable in some Porsches. I DON'T think that free-flowing filters necessarily contribute to that type of alert.
Then again, what do I know? But, it's now 2 authorized Porsche dealers/service centers that I have spoken with who recommended BMC usage to me. It seems some mechanics seem to prefer them, particularly when paired with aftermarket exhausts.
Go Bucs! Thank G0d for the bye-week.
