Intake Silencer Removal
aka Resonator Box Removal
aka Snorkusectomy (sp?)
Removing the intake silencer will give your WRX a better-sounding intake, a much more audible stock CBV (compressor bypass valve), and some people say your turbo spools up faster.
WARNING! Modification of your car can void your warranty
This is a fairly simple mod, so here it is:
Tools: flat-head screwdriver, ratchet/sockets (I think metric), open end wrench
Estimated time: 30 minutes
First, take off the air scoop by removing the two bolts holding it on in the front, and pulling the rear end off of the intake silencer. Then, remove this nut. Now for the hard part - remove the front passenger wheel and begin to remove the plastic clips holding on the fender lining. Use a flat-head to pry out the center (screw-like) part of these clips, then the outer (claw-like) part. They won't come out if you try to take the whole thing out at once. Take out all the clips to the right of the brakes, and also remove the little plastic panel directly below the headlights (this directs air to the brakes for cooling). When you have done all this, pull back the fender lining, exposing the "snorkus". Make sure you remove these clips before you remove the lining, or they will break. When you can see the intake silencer, remove the nut and bolt on the right side. Then, simply pull the whole thing out. You might have to remove the air filter and push from the inside of the airbox. Put everything back together (minus the intake silencer, of course) and you're done! Some people prefer to buy the rubber plug from the RS models to plug up the hole where the scoop met the intake silencer. That way, only cold air is drawn from the fender. Personally, I re-attached the scoop and left the hole open so there is never a shortage of air. Enjoy your new, cooler-sounding intake (and faster turbo spool-up?)
