Question Airbox mod?

Has anyone taken out the restrictor in the airbox by the fenderwell? Been thinking of doing this for some time, but dunno if its worth it or not.

Some on the old Yahoo Club have done this. It's extra tubing to keep the engine luxury-car-quiet. IMHO not worth going in there to remove it unless you are doing other intake modifications at the same time.

I did it a while ago, then took a small piece of the tubing from it, cut it off, and reattached it to make sure the air is being grabbed from inside the fender, not the engine compartment. To be honest, it was so long ago that I don't even remember if it had any effect on acceleration. The beast never seems to accelerate at the same rate each time anyways. In theory it should. In theory removing the screen in front of the MAF sensor also will increase airflow, but neither one probably did anything noticeable in the 1/4 mile. But it does sound a whole lot better and it was worth doing just for that.

I took mine out 2 weeks ago. I added a K&N filter at that time too. I reset the ECU and have noticed that the car is more throaty and seems faster via the ole butt dyno.

A few friends that have rode in the car before and after have noted the same things. Again, not realy dyno #'s, but it was worth it from where I sit.

I don't know how much is K&N and how much is from removing the intake silencer, but the combined results are very good.

Question

Is it easy to do? How long does it take? If its easy and reversible, I may just give it a shot just to try it out.

It's not too hard. I used the Impreza instructions here as my guide. They are about the same.

Kastle, thanks for the link to the instructions. I've been trying to do one thing on the car each week, will try removing the intake resonator this weekend if it's not raining.
