Has anyone added the above intake? Looks like the filter becomes unaccessable unless you remove the tube. Is it too low and in danger of getting wet or what is under the pictures. I have emailed the folks at GSM and no response. I like the look, but don't want extra hassles.. Your thoughts and experiences please..
P.S. yes I have read the ongoing issues with the s/c so maybe they are too busy right now..
I installed it last week. The intake pipe runs to a fitting that goes through the stock air-intake hole that you find when you remove your stock airbox, and a (large) K&N filter attaches to the underneath side of this fitting, inside the bumper cover.
On my 300C, the stock air silencer was still in place, so I had to remove it first (something not mentioned in the description or instructions, and which did make the install quite a bit longer than the 45 minutes it's supposed to take).
Installing the filter (or servicing it) requires removing the left front wheel and tire, removing the inner fender liner fasteners (re-usable fasteners were included with the kit to replace the "one-time" stock fasteners), and peeling back the fender liner. It's a pain in the butt, but probably not more than a 10 or 15 minute job to service the thing once it's in.
Non-official, non-dyno results -- it looks nice (I got the chrome version of the pipe), sounds great, and seems to have a noticable effect on throttle response (that I know probably would never show up on a dyno).
Downsides -- the filter location makes installation and service a moderate pain in the ass. I'm also concerned about sucking in water, although I seldom if ever drive the car in the rain.
There was a thread over on 3CF regarding a little donut-shaped device AER sells to place on CAI tubes as a failsafe for the water issue -- if the filter ever sucks up water, the increased vacuum pressure causes a failsafe opening in the donut to open, sucking in (dry) air through a foam filter. This would seem like a great idea for use with a CAI like this, except they only make them for up to 3" intake pipes, and this one is (I believe) 3.5". I'd love to find something similar for use with the GSM CAI.
I should probably also note that this is my first GSM purchase; I ordered it during the group buy a few weeks ago. I received a tracking number within 24 hours, and the part a few days later. Everything was included, and instructions (with pictures) were good, with the exception of not accounting for having a stock air silencer in place.
