What is it with these filters i thought they where supposed to be a good upgrade,as for power she pulled like a train on the way home.
I guy i bought the car from sent the orginal air box over in the boot so i could change over if i wanted too.
Why would this mod have been done in the first place what do you gain.
I have a full stainless steel exhaust would that be classed as a freeflow.

TBH it depends on the weather,speed etc etc,there are alot of factors in wether your Cone is producing more HP or not... dont take the ''your losing HP'' remarks as gospal
the only way you would know for sure is to take it a rolling road and do a couple of runs with and with stock...but your not gunna go that are yer

..
One thing for certain is you get the sucking air noice when you put yer foot down and that just adds to the lovely tones of the 6pot IMO..
Its made cuz in general these will give you a HP gain but also will drink more fuel though be it not alot in both cases but it is there! .. K&N dont take into account how hot these engines get when running outher wise the fookers would of made a heatshield for an E30

.. and that goes with all the cone makers..
So unless you get yerself a Viper Induction where the Cone is incased and is only linked to the outside worls through a hose running to the grill of yer car,your have to MAKE a heatshiled..
Ive seen another pic somewhere.. cant remember now but basically the e30 owner had a cone like yours and had made a tunnel/cover that literally could slide over the cone to the grill hence stopping any engine heat entering the cone..
2 things you gota do if you want to keep it:
make sure you have enougn air-flow to the filter,there should be a pipe/tube running from the front of the car be it the grill or around the wheel arch area which is giving you a nice flow of outside air when your moving AND you HAVE to stop engine heat from entering the Cone as much as poss..
Seems easier to change back to the stock filter agreed... but depends on how much yer like the grunt!
