I was just wondering if the diameter of a cold air intake off of a gsr was different than the one for an LS i was looking into AEM and they are two different part numbers but e few people on EBAY seem to think they will fit. Since i am short on cash i was hoping that they would fit so that i could get one used off of ebay for alot cheaper than a new one. But i cannot find any that are for non-vtec motors on ebay
Don't do it, the diameters are diff. (2.75" vs. 2.5"), but more importantly the GS-R intake manifold sits much lower so a GS-R intake on an LS will sit really high and fit badly. I bought a used AEM CAI that this guy said was for an LS, but it turned out to be a GS-R one. The pipe comes up high enough to prevent me from using a strut brace, and the piping rubbed the body badly enough that it developed a gouge that went all the way through the metal. Get an LS one, or if you plan on making more power than just i/h/c/e, get a Type R one. My Type R CAI should be here tomorrow. The Type R intake is 3" and is shaped the same way as an LS one. Good luck.
P.S. I have a bypass valve for an LS CAI for sale if you will need it. I bought it before I knew I had a GS-R intake, I didn't install it luckily, so it's brand new in the box.

Mods: That's for me to know, and you to find out...
Not only that, but the bends on the GSR CAI are way different that those of the rs, gs, etc. The GSR has a somewhat odd intake manifold that bends down...while the rs, gs, and even Type R don't...so in other words...don't do it!!
Just because it says it's for a Type-R, DOES NOT MEAN THAT IT WILL IMPROVE YOUR CARS PERFORMANCE! the ITR intake ppipe may meet at the TB on the IM but, the diameter is not the same.
Getting a part that is made for another car may or may not work but, at the same time may not provide the maximum performance gains possible and in some cases may even harm the cars performance and affect the part or the cars longevity.
Putting a larger diameter Intake than Throttle Body inlet size will create turbulance at the TB opening and will NOT allow for the "Best" flow possible or the Maximum performance gains.
Save your money and get the correct model for your specific car.
being a noob on this board you obviously took me the wrong way. I didnt get a chance to explain why I got the 3" so dont go and put me into the category of "I bought it because it's for the TYPE R" or "bigger is better" I got the 3" one strictly because my car is lacking high end power (being an LS and all) I also have the DC sports 4-1 headers to go with that. I'm also upgrading my TB and IM later on so I didnt see the point in getting the LS one when I'm gonna need a bigger diameter CAI down the road.
"Save your money and get the correct model for your specific car." The Type R one costs more than the LS one, whats your point?

Yeah the AEM Type R CAI is just their standard CAI in the Type R application.
1Greyteg, I personally went with a 3" intake pipe because I believe my application had sufficient demands to warrant the bigger piping, that's all. I surely didn't buy it for the sole reason of "it is bigger so therefore always better" or "it's a Type R so it must be better," please please please don't put me into that category! After doing a LOT of reading about intake designs and such, I finally decided that for a 150-155whp LS motor, a 3" is probably a better idea than a *puny* 2.5" intake pipe. Put very simply a GS-R AEM CAI is 2.75", I'm making more power than a GS-R, so why should I go smaller? I need more high-end power anyway, which the Type R intake will probably give me over the LS's low-end power because of the flow characteristics of the different diameter pipes. Plus I may bore out my TB to 62mm sometime fairly soon.
If all one is doing is bolt-ons and that's where engine work will stop, by all means the LS 2.5" CAI will be the best idea for your LS. Don't be sucked into the Type R mystique and don't be attracted by the "hey that thing's huge, it must be the best for flow" idea.
