4) Take lid off airbox:

The right side of the airbox has clips that slide into a lip on the bottom part of the airbox.

8) All done now put it back together.

Conclusion:

The mod is simple and the Dremel cuts through the plastic very easy. Install took 30 minutes. You can definately hear the SC whine when you get on it but it is still mild. Personally I think it is perfect balance, not to loud and not too quiet like stock. When you nail the throttle cars around you will know your blown :thumbsup:

Thanks Jess (WAIT4ME) for sharing the mod.

^ from what i read this was good for 5hp...Now this is with the crappy oem filter but if you went with a good filter like a green one from http://www.greenfilterusa.com/ ( better than K&N, higher quality materials ) I can guarantee you'd pick up probally a total of 10hp. I dont know if they have one out yet for the V but i'm sure they'll come out with one soon enough.

Thanks for that write up, It is very good.

The 5hp was if you just do it with a bone stock tune and no other mods..

With our tune, and you do this adds 20 hp to the wheels. I posted the dyno graph for it over at ls1tech. Ill try to merge the posts over to this site tonight or tommorrow.

When i quoted hp gains, it was on a bone stock configuration for each mod. Back to stock, then mod one thing, re dyno.. back to stock, add mod, re dyno..

That way it is easier to pinpoint what gains can be had in stock form. :)

Ohh and as for no filter vs stock one vs V6 cts k&n "which is the same part number as for the V" No filter change made a difference in hp. I tried.. :D

Do you have to buy anything or is this just simply cutting the bottom of the stock box off.

Is the airbox part available from GM? If so, what part number? I'd rather buy another, cut the bottom out of that, and save my stock airbox.

Maybe this is a dumb question, and if so, sorry... Is there a huge differance between this mod, and a CAI?

I'm a guy whut likes pics before I start cutting. What about the brake cooling duct? Has anybody done this mod and added shielding to keep out hot underhood air?

I pulled the brake duct and just put in a K&N filter. I felt better throttle response. Untill a proven enclosed system is put out there really wont be much of a gain with a large tube intake that just sucks up engine heat. Using the K&N filter though I like to dab off all the oil as they love to drown their filters in it. Not so good for mafs

I'm going to accomplish this mod when I return home, cheap mod and still keeps the V stock looking if needed to go to the dealership. Any special tips to know that the pic's in the post didn't show?

Thanks

I did that to my 08 CTS so I think it's a Drumstix airbox mod actually. :shhh: :D

There was a very similar and popular mod for my 2001 Bullitt Mustang that many owners (including me) did -- definitely opened up the intake noise at WOT on that car, so I can only imagine on a SC system. I think I might order a spare box from GM Parts Direct so I have one to mod and one to keep original. Thanks for the write-up!

I don't think you are the first one to cut out the bottom of an air box. Many cars have been doing this for years.

Any one see an increase in boost by cutting and installing the K&N?

Cars are cutting air boxes? Ok, I get it, I think... :hmm:

Has anyone seen any negative side effects from doing this such as excessive dust or water contamination in the air filter? I think i am going out this afternoon to do this, kind of forgot all about it!

No negative effects that I have heard of.

I know someone else asked this but again, is this just a mod to substitute getting a CAI or is this something that can be done in combination with an aftermarket CAI by cutting the box?

Either or. A modified air box or a AAI( ambiant air intake ;-)

You can combine it with LPE's rigid intake tube to guard against potential stock tube collapse in high-output applications.
