DIY BMC Filter Install 991.2
I just pulled the trigger on a BMC Air filter for my Porsche Carrera 991.2 and was told the rear spoiler needed to be removed as well as the rear bumper and tail lights to do the install. Looking for a DIY..
Thanks

I'm pretty sure the bumper needs to be removed too. My tech had the bumper removed for the install.

I'm just trying to locate some decent step by step instructions just so I do not damage my car. I remember running across some before but I can't seem to find them now... I found this video buts it's on a 2015 and he has managed to take his bumper off without the spoiler removal..

Fans
Tail lights
Spoiler
Bumper
Just find some step by step instructions on how to remove the ECU. It will cover all of those except the bumper... The ECU removal is the final step so you can start from step 1 all the way till the removal step which you can skip. After that just find some step by steps to another project that requires removing the bumper and skip to that part.

Not to step on anyone's toes, there's a 911 (older model NA) video that tests an aftermarket air filter w/ OEM, back to back, on a dyno.
The aftermarket resulted in a slight gain at the top RPMs, but a loss through low and middle. The conclusion was that the OEM was a better all rounder with the low-middle gain outweighing the aftermarket slight high gain. This fits with what I have read previously.
Where the aftermarket was a clear winner was in the increased intake sound over OEM. The owner of the 911, if I recall, opted for the sound gain. One advantage for aftermarket filters are that they can be cleaned and re-usable, allowing to recoup the extra expense. They also look cooler if exposed.

I'm hoping since I am tuned that the aftermarket filter will result in a lower duty cycle for the turbos. Also keep in mind the old 911's were NA and currently all GTS's come already with a bmc filter not the standard oem paper filter...

I learn something new every day...I had no idea that the new GTS cars come with the BMC filters. What do they recommend service wise?

Wait what? I believe quite a few folks here on the forum with GTS have DIY'd their BMC filters.

So, if I get this right, my new Carrera S with dealer installed X51 PowerKit will need the GTS replacement filters, when I get to that point?
