If you're going to bother fitting an aftermarket filter you need as long and smooth an inlet tract as possible, and 3" pipe. Personally if the mouth of the filter is less than 76mm I wouldn't bother with it. I saw 10bhp difference at a rolling road just by fitting a filter a little on the small side, followed by a massive k&n filter.
If you insist though, silicone joiner, 90degree large radius ally pipe, then a joiner to fit the cone.
