Air intake differences 05 vs 06+?

Is there a drastic difference in an 05 GXPs air intake system in comparison to an 06-07 model :confused: ? I see the K&N CAI kit doesn't say they work with an 05 and am wondering what the differences are (if any). Anybody have some good pics of an 06 or 07 stock air intake system I can compare and contrast mine with?

Obviously my plan here is to put a CAI kit on my 05 and I am seeing if one for an 06-07 will work.

Thanks!!
 


Well, I do see that there are cheaper ways to get a filter setup that will flow as well, but this car is a year 'round Daily Driver in MN. I am not interested in anything that looks cobbled together for the sake of saving a few bucks and only works well when under hood temps are low. I want it to look professional and I want it to be as sealed from getting under hood heat as possible.

Plus I think I have found it for a pretty good price:

Ken's Auto Wholesale

That's $223.35 shipped.

I like the added power the CAI gives, but the added mileage and washability makes it pay for itself over time for my situation. I've got a 98 Trans Am WS6 for any serious racing situations :th_biggrin1: , so I don't need to eek out every last HP at the lowest cost possible. Just looking for a quality, no-fuss, CAI setup to gain some power and mileage that is reusable forever.

I just can't figure out if it will work on my 05 or not???
 
i just got a new intake for my 08 grand prix and im a daily driver in mn also. Mine costed me only 65 bucks and it looks nice imo (chromed out)

1) The difference in temp shouldn't matter. I as good as proved it.
2) Open cone looks a ton better than a box, according to nine out of ten inmates. I'm actually serious - the guys who show their GP's typically refuse to use a "cai" box because it's ugly
3) K&N box doesn't seal out heat worth a shiit. Have you looked at it? Paper thin plastic? It'll be just as hot, extra restrictive, and you'll make worse power and worse gas mileage than open cone.

K&N box is open on top - you don't want to leave your filter uncovered when you detail your engine bay, box or not. Just stick a $45 9" K&N cone on there and call it a day - save that $180 for a mod that actually does... something, instead of a silly piece of plastic.

But then again, it's your car and your money - do as you will, big spender. :th_thumbsup-wink: We're only trying to point you in the right direction and be helpful trolls.

Good luck!

Edit: Just to be sure we're on the same page, you want one of these things, right?

Well I see this is a very hot topic for some people here...lol. I read some other threads before posting this one up and figured it might trigger some direct responses. I'm not a big spender, but I can afford to spend more than a few dollars on this project without breaking my bank... And my time is definitely worth money to me and my family these days, unfortunately.

I understand where some of you are coming from, but a cone filter on the end of the factory intake tube that is flopping around in the vicinity of where the stock airbox was is not something I will entertain. Aren't there some components that will end up loose and not mounted to anything as well if you don't use the factory airbox or something like the K&N? I need to dig into this some so I know what all is going on under there...

Can you link me to or post up that data that proves out the open cone setup as being superior?

Also, I have a 2000 Silverado with a K&N CAI kit on it, and that shield is made out of metal... Is that not the case on the one for the Grand Prix GXPs? And doesn't the shield butt up against the hood when it is shut to create the top of the "box" where the filter resides? Again, that is how the one on my Silverado works... It doesn't seal off completely, but it does a pretty good job of blocking the hot air from around the engine from getting pulled into the filter. And I am pretty confident in my abilities to not hose the filter down or get chemicals on it when cleaning up under the hood :) .

Thanks!
 
cone slapped on throttle body looks better than a CAI box. better gas mileage too.

No offense, but I disagree. Moving the filter away from the engine to get more cooler, denser air looks much cooler to me :) .

Plus you can't put it on the TB unless you retune it to run Speed Density and ignore the MAF.

negative, all u have to do it put IAT sensor near the cone... its been dyno proven from a member on here.... open cone had greater HP and TRQ numbers. do what u wanna do though.

Ahh... No. That sensor inline of the air intake system is not an IAT sensor - it is an MAF sensor. You must have the MAF connected or the PCM will identify that it is missing and, among other things, set a DTC and not run optimally.

As for dyno results, I would like to see that data, as I stated above.
 
when looking through the other threads i stumbled upon one that it said it was proven that a CAI provides .5 horses more than an open cone. So if you feel like spending an extra 150+ dollars then go ahead. the open cone i got connects to the MAF and it has a bracket to mount onto your car so it does not bounce. The company i purchased mine from is custom made for each individual car
 
Just put a quality dry flow filter on the end of your maf sensor. Also you can run a filter condom if you are worried about the salt and crap in the winter.
 


my bad... i totally forgot we were talking about a GXP... ill see if i can find those dyno sheets on here.
found it pretty quick

No offense at all to SlowNA06, but that test is not very relevant for a Naturally Aspirated application... A boosted car with no intercooler setup is going to act differently than a naturally aspirated car at different temperatures and atmospheric conditions. But what it does tell me is that an open cone system flowed nearly the same as that particular CAI system - which is more of a plus for the CAI than the open cone if you ask me... It means the CAI, even though it has less fully exposed surface area, flows very nearly as well. And the K&N is pretty much an open cone since it uses the car and one shield for it's "box".

But really the numbers are so close that they really don't suggest either setup will make more power. We're talking about a DynoJet here. I don't know how many of you have worked with them before... but they are well known to have variances even on pulls made back to back - which the guy almost did in this instance. I know I'm new here, but I'm definitely not new to modifying and racing cars.

I'm going to dig into the system on my car and compare to the pics you guys posted and see if it looks like that system will work on my car.

Thanks for the pics and info!

Well I don't just "feel like" spending the extra money... I just see some of the benefits of buying something that has a nice finished look and is a smooth, easy bolt in that ties up all the loose ends and eliminates the flow shortcomings of the stock system but also pulls as much cool air as possible into the engine...

Please post a link to this - it would be useful for those that don't want their stuff bouncing around... and think zip ties look shabby.
