Ben, It looks like you're asking about cold air intakes. You said it was a 2003, and not a stick shift, so that means that it isn't a GT. The 2003-2008 GT's had a six speed manual transmission and a different engine than the base and AWD's, and the difference matters when buying a CAI The base engine is often referred to by it's engine code of "1ZZ", the GT has the "2ZZ" engine (in the 2003-2008 model years) I haven't installed a CAI, don't know off the top of my head if there are different ones needed for base auto tranny, base manual tranny, and AWD. But you need one for the 1ZZ engine, base auto tranny. I'd think people here would be glad to see someone asking about performance mods instead of another gas mileage thread. There are people here who are very familiar with all kinds of Vibe details (which is why you came here inthe first place), sometimes we forget that not everybody shares the same knowledge. I think someone was trying to point out that you posted a link to an intake for a GT, but that you would need a similar but different one.The search here won't let you search for three letter words, so you can't search for things like CAI, SRI (short ram intake), a number of other things that would be useful to seach for as well. So if you tried to search fo CAI, you'd have gotten no results. There are a lot of discussions about CAIs, sometimes it's hard to find them though. IT helps to get creative with the search. There are 180 threads that have the word "intake" in the title. There's been more than a few times where this site's search has made me feel like a moron, so don't let that bother you. So try that, see if you can find one of the older threads where people were discussing which intake to get. THere are a few respected name brands of intakes people here seem to favor, I think some of those have been posted in the replies you've gotten so far. There is a good thread Poor Man's Complete Performance Mod Guide for the 1ZZ-FE(Vibe Base & AWD) for Under $1200 It lists some of the less expensive things you can do to get more power out of Vibes. Another really good thread is The Great How-To Modification Index! It lis an index of threads that provide information and instructions on how to accomplish a wide variety of modifications. There's one on Cold Air intakes in that list, woudl be a good one to see what is involved in installing a CAI.THere's another good site,
http://www.urbandictionary.com I use it a lot to look up internet jargon. I remember the first time I saw the term IMHO (in my humble/honest opinion) was in an email whhere someone replied to me by saying "Well, IMHO, I think ..." and I got all bent thinking they were insulting me by calling me an imho, whatever that was, really pissed me off even though I didn't know what it meant. When I found out, well, it made a difference. Not necesarily the case here though, that site defines flamed as "being attacked online/on a forum.to be flamed.usually overly harsh, and often using references to personal information.flames are an unfortunate, but inevitable, element of unmoderated (or user moderated)forums. often done "anon""There's generally a low tolerance for flaming here, we're usually a friendly and helpful bunch. If you do run into it, don't take it personal, some people are just like that. They are trying to help, in their own way. I think you'll find this place is a lot better than many other forums out there in the wilds of the interweb.
