DIY Air Intake

2000GrandPrixGT2000

Hey guys I am looking to make an air intake similar to Nawarkk's for my 2000 Grand Prix GT. I currently have the stock air filter on there and am looking to put on a spectre air filter. Here is my parts list:

Coupler to connect tube to TB: http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Coupler-Reducer-4%22-to-3-5%22-Spectre_22905797-P_N4023B_P|GRP2026____
Tube: http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_4%22-Aluminum-45-Degree-Elbow-Spectre_22905794-P_N4023B_P|GRP2026____
Spectre High Flow Air Filter: Advance Auto Parts: High Flow Air Filter by Spectre - Part 9732

Will that work out? I can drill a hole in the tube to mount the IAT right? Will I need extra support to hold up the filter? Any comments, suggestions, or concerns are more than welcome so feel free
I am very new to this so I am looking for all the advice I can get :th_thumbsup-wink:

Alright so I edited it because I was told that a 4" tube would work out better
How does that look/sound?
Where should I drill the hole for the IAT?
Any suggestions for supporting the filter and keeping it steadyl?
 
I would not get another coupler to go from the tube to the filter.. I mean unless you really wanted too. Seems like a waste since the filter can fit different sizes.

IAT sensor I would drill a hole for it in your 4" tube, granted it's not too hard. Try and drill it close to where it originally was located.. I doubt this makes a difference but hey just throwing it out there.

If you get strong clamps between the TB and the tube, your filter will go no where, trust me. The only thing I would caution you on is your PCM. Put some more tape around the wires so that IF the filter rubs against them, it won't short circuit them.
 
So I could just tighten the filter directly onto the 4" tube with a clamp without any problems?
I was going to use the coupler because I thought it would hold better but if it will hold good enough with just the filter I will just use that
 
It should be more then fine. If you start noticing the filter sliding off, then I would go ahead and use the coupler for a more secure fit but try it first without the extra coupler and see where that gets ya.
 


Hey i have the same exact car a 2000 grand prix gt, and im looking into doing the same by installing a cold air intake and making it myself like your doing. Is there anyone that has a guide to show how to go about actually taking off the stock air filter and putting the new one on? I am pretty handy but have never done any work on my cars engine before and am not too familour with parts to the engine and what not to touch and i dont want to do any harm to the engine and unbolt a wrong bolt ect.

Any help would be greatly appreciated I'm sure im going to be getting flamed for not knowing much but whatever, you have to start somewhere right?

Start by taking of the black diagonal bar. Should be two 13mm bolts towards the front of the car and another 13mm bolt towards the rear. There is a sensor clipped to the bar. Just squeeze the head of the clip together and yank it out. Now you should have the bar out of the way. Go set it somewhere else.

Ok now.. I would start by taking off the corrugated rubber pipe. Disconnect the IAT sensor from the rubber. It's not hard to take it off. Use a flat head screw driver if you have too. It's kinda hard to take off the rubber from the throttle body.. You have to really pull hard on it. I used a flat head screw driver to angle it out from the Throttle body. There is a clamp that connects this rubber pipe to the air box. Undo that and you can yank the rubber piping out.

Okay.. not the air box. There are two little clip type things on the air box. Undo that and you can split it apart. The air filter should come out now. That piece you unclipped should also be able to be removed. The piece you unclipped should be where the rubber piping was leading too.

There is now two little bolts that are horizontal.. they are really small and I forgot the size of them. Remove those and the air box should split in half now.. Remove this part and then pull the PCM (computer chip) out from where it was resting. You have to pull directly opposite of the way it's sitting since it's a bit hard to get out.

Once that is out, the res of the air box is just clipped. Just give it a few good yanks upward and you should be able to get it out..

And there ya go.. now you can work with making a new intake!
 


I spoke to a friend and he said that on the pipe leading to the engine there is a sensor wire that should be removed as well and when i get new piping i should get one with a sensor hole to re connect it to, or instead i can simply drill a new hole in a piece of the pipe and put it back in?

As far as the instructions above on removing the air filter after i remove all of it do i still need anything, such as the computer chip you said and some other components that might be important?

Just want to fully understand everything so i don't cause more harm than good and so i dont have to spend more to bring it to the shop if i mess something up, thank you so much by the way very helpful and I am glad someone is willing to help me.
 
your plan sounds familiar

CTKGP do you remember the exact measurements of the pipe ect. you purchased or did you get the whole k&N package with everything included?
 
i bought a 4in coupler, a 4in tube with a 45* bend and a K&N filter all from summit

the tube was just one size if i can remember whole thing cost me like not even $70
 
What size hole did you drill to fit the AIT sensor into the chrome tube?
I was hoping my final product would look close to that, thanks for the picture
 


I just fabbed up a homemade 3" fender well intake today, ran me $49. It looks good, sounds good and performs well too. I originally fabbed up a 4" FWI but it didn't fit as well as I liked so I went ahead and switched to 3", figured it would feed my stock GT well enough.

I used the stock rubber elbow that is attached to the TB. It does have those restrictive ripples on it so I shoved the 3" PVC up until the bend where it is smooth. I then attached a 7" long K&N cone filter to the other end which sticks inside the fender well (I had to do a little cutting to the brace in there). I have a roof flashing keeping the hot engine bay temps away from the filter which also makes the install look cleaner too. I'll post a pic tomorrow, definitely easy to do. No offense to the guy above but don't run an open cone in the engine bay like that unless you like to suck in hot air, kind of defeats the purpose.

Here is a good thread to check out:
http://www.grandprixforums.net/make-4-fenderwell-intake-fwi-20.html

A couple things to remember:
- The largest diameter piping you can fit in there the better.
- The largest air filter you can fit the better.
- Bends are your enemy so keep them to a minimum.
- You want to keep it as short and direct as possible.
- You want the inside of whatever tubing to be smooth.

i didnt have the exact drill bit, i had a smaller one and just kept widening it till the sensor fitted. just use some kind os sealant or glue to keep it in there and so it wont leak
 
I've found some 4" tubing that it 35* and some that is 60* near me. Couldn't find anything 45*... I'll have to keep looking. I was checking out my filter on my nice FWI today and it was DIRTY!!! I'd like to keep it a little cleaner and make it so that I didn't have to take things apart just to get the filter out for regular cleanings.
 
cleaner would be filter in the engine bay

btw mk frilla, thats a 7in long filter just to let you know. filters come is a bunch of sizes, i would get a t least 5 or 6 inches long so you know there would be no restriction. or go big and get a 9in filter!
