From my expirience I say it is not worth it. I have a neuspeed p-flow intake on my gti which is a k&n cone filter and a heat shield. On days when it rains some of the moisture I guesse gets on the filter and until it drys out, the engine doesn't run smoothly. If You really want to do something with Your filter i would say just instal k&n drop in filter that's it, but do not expet any noticible power gain....
first off, I JUST made a topic about this, you just have to L@@K. Secondly, I have searched high and low, and only bavauto.com sells a good kit for e34. There have been conflicting stories, so I ordered one and when I get it I will post my findings. But, cones DO increase throttle response greatly, as on my old E30 it made spectacular difference.
I read your post, and i posted in it. It wasnt about this specific topic, you were talking about the entire CAI kit. thats not what i want.
I was simply asking if the cheap filters are bad.
Also i dont want any noticeable power increase. Im just looking for something that will make the car have a little bit more aggressive sound at higher RPM - and i know that the cone filters and removal of the air boxes do that, but you have a good point about the filter being wet....
there really shouldnt be a huge difference in filter to filter, quality is important especially with CAI versus the normal short intake with cone.
ive used a crappy intake on my CAI and it was fine, just maintain it properly and also do yourself a favor and buy the K&N recharger kit, it will work even though its not a k&n
well universal in general does = cheap, but when your talking about cone air filters, theres not really any specifics, its just mouth size over the pipe. even K&N calls them universal air filters. I just can't seem to justify spending 38.99 on an AIR filter. Is there any other company that makes disposable cone air filters? <sigh>
