Stock air filter?

insignificantly.

ok great im just looking for a little more flow on a cleanable filter so it sounds like the pro dry is a good fit for me

For ease of service, a drop-in is probably not a bad idea. Otherwise, no real performance gains, as others have said. I'll probably go with a Green filter, when the time comes.

What is a better flowing Aftermarket air filter That fits in the stock air box?

AFE touts 51% increase in air flow.

I stick with OEM stock filters for the best filtration. I don’t want to chance any extra dirt or contaminants entering the engine for little to no gains. I’ve had an engine go on me with cylinder scoring from who knows what, but it did have an afe dry filter on it.

Surprised they don't have one out yet.

You get about 7whp with a drop in if you're tuned. I just reinstalled my K&N filter, car definitely feels peppier. I may switch to the afe oil filter since I've seen the quality is a bit better than k&n.

im not really looking for gains vs just the re-useable aspects of it....

Unit 7371 is supposed to fit the Supra.

Another K&N filter here. Easy drop-in filter. You can hear the induction sound a little better with it installed. For the price/performance I'm happy with it.

Have you noticed any drop in low end torque / throttle response? There are some BMW owners who have noticed that they have lost some power down low, but gained a little up top.

I've run the stock, K&N, and aFe filters (and have an HKS I need to install) and I haven't noticed any loss of power down low or gains up top. I have noticed a bit more induction noise when stomping the gas low in the rev range in a high gear.

I decided on BMC. After going back and forth so much between keeping with the stock filter or this brand or that brand I eventually threw my hands up and said, "If BMC is good enough for Porsche then it's good enough for me." As far as what difference did it make, I haven't noticed anything. That being said I'm no Niki Lauda.
