KN INDUCTION OR STANDARD PANAL FILTER ?
I have got a kn on my 95 wrx import and it runs fine but some people have said i am better with the standard air box and a decant panel filter. Would it make any differance or should i just leave the kn on?

It really depends on what power level you're at, and if you have fmic pipework preventing the use of the OE airbox.
The OE airbox wil prevent the intake air from being unnecessarily heated before being drawn through the filter - thus helping power output, up until the point the airbox itself becomes a restriction
If you stick with the IK, make a cold air feed to supply the filter
With an IK fitted, your MAF may not read quite correctly for a given amount of air flowing across it, and more than likely cause a lean fuel mixture condition - If you have an aftermarket MAF based ecu (like PowerFC ) it's normal practice to rescale the MAF to suit the particular filter fitted, to ensure the fuelling is correct
