thanks again for this. just intstalled em today. took a couple hours...taking the bumper off is the easy part. cutting those damn holes right is a problem...not really, my dremel just kept dying.

with this system do you have to remove the bumper everytime you have to clean the filters?

Yes you have to remove the bumper to clean the filters. Removing the front bumper is super easy though.

Don't get swayed by thinking it's difficult like I did at first. Digitonium made a DIY for removing the front bumper for reference.

Besides you don't need to clean the filters too often anyway. I'd probably do it every 20k miles or so.

Thanks for the DIY. I know I will be religiously reading this when I install my G3 intake (which soon be soon :))

ADDED!

I used this write up to help me this weekend to install - thanks. 3 things I would add:

1. Step 10 - it does require you to remove the bolt that holds the air inlets in (not just the tabs)

2. Step? - when you have to remove the cover near the window, to get to the two bolts for the strut bar, it has a bunch of plastic tabs holding in. Don't fear, just keep pulling up and it will come out - I was very tentative not to break anything, but in the end, I shouldn't have worried as they are pretty strong tabs, molded into the part.

3. Step? - when you test fit the lower tubes through your dremelled holes, cover them with the blue painter's tape, because they go in and then turn, and will most likely (guaranteed) rub against metal and get scratched. I had to put them in and out a few times to get the correct fitment, and by the end had various scratches (not that I really cared, but some others will).

I also used the DIY for the Bumper Removal, and looked at Semtex's install thread (in the Intake section), as it has more pics for the actual filter/lower tube placement. You will notice that there are several positions to put them in, all of which are very tight - make sure you cover all of the wires/hoses that touch this tube, as long term you will have some vibration and rubbing.

Also, look at my install thread as well, as I have a few more suggestions as well. Lastly, take your time, do it right the first time, and check all of your clamps.

Holy crap that's a lot of work to install an intake. Hope it's worth it. Guess I'll know soon enough when I do mine.

It took me about 5 minutes and a screwdriver to change the intake on my old 99 TransAm.

Yea its alot of work on this car but very easy. I took less then 10mins to do a intake on my cobalt, but there was only one and u didnt have to remove the front bumper...lol.

Awesome write-up. Thanks Snakes.

more diy should be like yours OP. i like how you circles all the points of interest like bolts and pins that need to be popped off.

im surprised a dremel is needed? why would stillen make a product that wont fit unless a dremel is used?

They had a whole lot of design variations, they decided on this one because the filter location achieved the best gains, only way to get the tubes with a proper bend is to cut into the radiator mount, its really a simple procedure and doesnt weaken the integrity of the mount whatsoever.

Not sure why stillen made it like that but its a easy step to do. And from what i seen, GTM's TT Kit and i think Stillen/GTM's SC kit is also the same, the pipe goes through that same spot.

Just installed mine yesterday with my son. Not as easy as I thought (took about 4 hours) but that's coming from a guy who has never taken a bumper off in his life.

I did not remove the engine cover or cross bar either. (didnt have deep sockets and didnt want to go to sears to get them)

It wasnt too bad although I'm scared to death I did something wrong somewhere and I'll find out about it sometime in the next month while I'm driving.......

Hopefully not!!

I placed a piece of hose over the AC line and taped it in place. I guess when I have someone install my HFC's and CBE I'll take the bumper off again and check for any wear.

I will say that I noticed a difference when driving. Second gear, at 3500-4000 RPM was impressive. I don't have numbers to back it up, but it sure felt faster. (traction control light came on a well)

you what, what, in the what, what? lol. Please explain that better...you shouldnt have to tape anything, if so...u might have issues in the future. Also u dont need a deep socket to take the strut bar and engine cover off, a simple 10mm and 14mm socket will do

I just did this this weekend and searched all over this site for help, unfortunately i never found this topic. Perhaps that's because Stillen is spelled incorrectly in the topic title. Perhaps an Admin can fix that up. None the less great job on the write up and everything said here is true.

Only thing I can add to any of this would be

1 you really dont need to remove the cross bar to get the stock intakes out so you could save a little time not hassling with that.

2 the bumper isn't as scary as it seems. It's really light and pops right off as stated.

3 be ready to reprogram your power windows after you hook your battery back up. Link to that here.
