I never understand the need for stuff like this. It seems Porsche, a performance company would have worked out the best intake filter to maximize performance, yet the aftermarket touts benefits. Maybe Porsche is constrained by the need to provide better fuel economy?

 

it’s a $300 air filter - porsche is also constrained on supply chain logistics and reliabiltyi and costs - they are in fact the most profitable car company in the world - they are known for performance but also know these days for shaving costs where they can - tripling or quadrupling the cost of EVERY airfilter going into EVERY Cayenne is not a smart business decision - especially when it will make little if any performance difference that they can market

I installed this filter on my wife’s ‘21 TurboS eHybrid - my hearing must be shot given my age and hard living, cause I can not hear much of any difference - but the filter is remarkablly better build quality than the OEM model it replaced and it’s “red” so it must be faster.

 

To me it’s the cost of ownership, $300 “lifetime” BMC filter vs. $60 one time use OEM filter. I know I will keep the car long enough (if everything goes well) to change the stock filter at least 3 times throughout the ownership. So that’s $180 if I stay with OEM filter. I can easily sell the BMC filter at 2/3 or more of what I paid on forum to recap the cost (done this multiple times), so $100 at the end. You may argue I need to wash/re-oil the filter every year and possibly ruin air sensor but so far I have not had any problem with it the past 15 years.

The extra performance including more turbo spool / intake noise are bonuses to me

 

I have used the BMC filter in many of my cars, both for everyday use and for motorsports.
You should not expect spectacular results after installing this filter. This filter does not increase power (depending of the car, maybe 2-3HP more, which is unnoticeable), it slightly changes the engine sound (turbo whistle) and slightly improves throttle response at low revs. Some say it improves mpg slightly. All these changes are almost imperceptible and you need to know your car really well to feel the differences.
The advantage of this filter is the fact that it is "lifetime" and requires only washing and oiling. When oiling, you need to be very careful not to overdo it with the amount of oil used, as you may damage some engine equipment.
Please remember that this is a high-flow filter and, as is often the case in life, it is something for something. This filter does not filter as well as the OEM paper one. Therefore, I would not recommend it to those who use their cars in highly dusty areas. I would also not recommend it for cars with a MAF sensor (mainly diesel) because excess oil from the filter may damage this sensor.
Porsche Cayenne does not have MAF but it does have MAPs. This sensor is less delicate than the MAF and can simply be removed and cleaned with a sensor cleaning detergent. MAP contamination may occur if we overdo it with oil during cleaning, but usually nothing bad happens especially when the filter is oiled by the factory.
This type of filter is often used in motorsports where high-performance engines need additional air. But such engines are tuned for such filters. In normal cars, especially with turbo engines, the engine computer is programmed to the efficiency of the OEM filter and will set the parameters variably depending on the current air supply, fuel and load. That's why the effects of using high-flow filters in production cars are negligible or non-existent.
However, there are car manufacturers such as Lamborghini that install BMC filters in some of their models from the factory. Well, here the Italian company must use Italian filters (BMC is an Italian company but belongs to K&N).

 

I had BMC air filters in my 991.2GTS and couldn’t really tell the difference in sound & performance. I’ve tried other “performance” filters on several performance vehicles with same results. Some have dyno’d their cars and the power difference was insignificant. This debate, including cold air intakes, have been pretty much beaten to death in many other forums. If the placebo effect works for you, then you’ve achieved your goal. I’ll take data instead. At the end of the day, it’s different strokes for different folks!

 

Just did my 2024 Cayenne S e hybrid Coupe today. Simple install just looked at video online real quick to find quick release clip positions. Only need to unscrew two T25 Torx screws that hold OEM filter in place and then remove similar holding screws from BMC before installing it after removing OEM Porsche filter. Viola. 😎

BMC model FB01023. Universal fit for V6/V8 Cayenne:Urus/Bentyayga also!

Nicely packaged plus cleaning kit ordered

Air filter/OEM cover.

Nicely constructed

OEM filter placement

BMC filter vs OEM Porsche filter…a bit more rugged construction. notice Porsche OEM is made by Mahle

Install done…great fitment. No gaps.

 

Did you hear a difference though?

 

Short drive...no CEL or any warning lights. Check. None expected. Turbo/intake noise s a bit more pronounced but no additional exhaust noise and likely HP gains if any cannot be felt...car is fast enough as is. But for me cheap mod and given cost of intake replacement after one or two air filters the lifetime filter pays for itself a bit. Simple and cheap mod/upgrade.

 

I have the same BMC filter, can I drive the car without the plastic engine cover???

No, the car needs cold air from outside, not hot air from the engine compartment.

 

Why haven't APR and other tuners come up with a cold air solution for the 2024/2025 Cayenne S (9YB)? @APRacer

 

Mod for SUV is a low priority as majority of owners don’t bother

 

the factory solution is cold air, yes? air is routed cold and remains segregated from the hot air as designed by porsche.

apr has the other set up w the carbon fiber component connection between the filter and the turbo, for 2.9, 3.0 and v8: https://www.goapr.com/products/engin...parts/CI100055

 

Does NOT work with 2024+ Cayenne S
