I will definitely do this soon. I have always found that higher flowing filters give a subtle but noticeable improvement in early throttle response. Also there is more intake sound, and as I discovered first with my e92 M3 from 2011, if the engine sounds really good, the exhaust sound doesn't matter as much

IMHO, changing to a “high flow” air filter is a bad idea. The more air you let in, the more crap you let in regardless of what the manufacturer may state. On top of that, there is no way you would ever actually feel any difference in power. However, the placebo effect will likely be real.

It wont make a noticeable difference with thestock exhaust other than intake wooshing noised snd deeper cold start/revs. However, decork the exhaust and intake side starts to matter especially with tuning. Then power becomes limited by fueling

It's not about more power. You will make little to no extra power. However, since more air is immediately let in, your initial throttle response feels sharper. Not night and day, but this is a cheap mod. Sound is better also. So it basically improves the subjective driving experience.

For the practical life of a car, the the less restrictive filter makes no difference. I have run almost every car I have owned with high flow filters. Some for 6-7 years, and have had no issue whatsoever. If you want to run a car for 300,000 miles, I don't know if it matters or not.

Power wise you wont feel anything but if you run a K&N or BMC one of the pluses is that you can take them out and clean them...and believe me, on these mid engine cars you will be doing it every 3-4K miles.

To each his own, my method is somewhat relative.
i do switch oem filter to free flow air filters Only on racing seasons as i enjoy the better throttle response and yes it does a slim deference in the track but not much on the street which is why i switch back the oem's after i tap them with my hands before i return them back when thee race season is done. in the street especially where air filteration is a factor to you then use oem as its generally excellent with normal restriction and for auto cross and circuit where without much traffic use aftermarket inn the end. just my 2 cents

Because they have to build these cars with daily driving in mind and they also have to build them for people who don't change their filters. They also have to be able to manage in the dirtiest of conditions. If you are using you car to commute daily in a polluted, heavy traffic setting, a high flow filter may not be the best choice. If your car is a toy that sees less than 5000 miles a year of country driving and the track in dry weather, you will be fine.

I agree with VVG. They do work, but aren't for everyone. The ones in my Macan S definitely improve throttle response and add a dyno proven 10 hp. I only drive about 3,500 miles a year on this daily driver though.
