K&n induction cone on Subaru classic
I fitted and induction kit to my 97 impreza if I blip the throttle slightly you can hear a noise coming from one of the sensors on the strut tower same side as the filter. Has anyone had the same issue. It's only happened since I put it on

Ha, I wasn't getting at that.
As suspected, it's no doubt the BCS clicking away.
I can hear it on mine sometimes - ever since I had it mapped, inc. a cone filter, etc. At first I wondered what it was. Then realised it could be the BCS. So I did a test by temporarily disconnecting the connector between it and the ECU. Hey presto, sound gone.
You can do that quick confirmation test too...

Oh I forgot!...
When I first heard it it was quite loud (it's the 3-port VTA from the A'PEXi boost control kit). So I simply bought a universal thick rubber exhaust strap from Halfords, neatly cut it to the right size, and screwed it down between the BCS bracket and its inner wing mounting position. It works well. You can still hear it when idling...sometimes...but not enough so it distracts you/drives you nuts. It's very faint.

Yes, my rubber 'gasket' mod was to attenuate the volume of the BCS clicking noise.
Because without it in place, the clicking was being transmitted through the BCS body, directly to its mounting bracket and on into the wing, thus amplifying the noise.

Each to there own. I'm pretty sure I'm not the only one running this set up .My last Subaru had a ramair cone .I don't go racing with it .I'm a enthusiast if anything. My boy racing day's on the rds are long gone.If it ever did go bang I would rebuild it as it's what I do for a living so I don't mind.I know of a classic import that had a stone go through his cone and got away with it.Is there actually any hard evidence that cones destroy mafs,Not just pub talk I mean .I'm always interested in learning some thing new. I work at Ford we have tuned focus rs here with the cones on with mafs and still running strong
