"performance" panel and cone filters are a well documented complete waste of money on an E30.
Buy good quality paper filters and replace regularly - best filtration and power.

Can you find them, because the only proof I've ever seen on here is that there is NO gain, which is why the Wiki states this:pnd wrote:panel filters have proven dyno gains they have been posted on here

If you can dig out the dyno results that say otherwise, I'll happily modify the Wiki to accommodate them.

i can't be bothered to find them but a guy a couple of years ago tested k+n and normal and a cone and found small gains in both bhp and torque. I have had these cars since the mid nineties and always fitted a performance filter and always found them to be more responsive.

In letting through more air they filter it less meaning more crap going through the engine! OEM filter is the way!
