lol... more CAI questions
new member here....
i've been gobbling up all the info in this forum about adding a CAI, but I'm not very mechanically inclined so i have just a couple more questions. first of all, i've seen that many people use a k&n 4750 xstream filter, but i didn't know if that would be an appropriate filter for my car. the k&n site says "for racing purposes only" (ha ha), but i'd like to know if there are better options for me that may also be a little cheaper. in addition, i live on a dusty gravel road, so this might be a factor. second of all, i was wondering about completely removing my catalytic converter. is this possible, or are there sensors in the cat that are necessary for proper operation? i know it may be on the fringe of illegal, but i don't think there are any strict emissions laws in the great state of iowa. if it'* possible, what will it do for my power and exhaust note? all responses are greatly appreciated.

check his sig, Twister, he has the same car as us.
OK bignews...the Xstream filter is probably overkill for our cars, we dont suck nearly as much air as a supercharged car does. There was a link in here the other day to a site that had the different K&N filters. You need some sort of cone/cylinder with a 3" ID (Inner Diameter) for the pipe. We have found that the cheapest option is a pipe for a honda from autozone, and a rubber coupler from a home improvement store. The dusty road shouldnt be that much of a issue with the K&N, the only thing is that you might need to clean it more often. If you are really worried about it, they sell little covers to go on the filters for dusty applications.
For the cat you would be better off to get a high flow one installed. You will need some sort of oxygen sensor spoof if you decide to remove the cat, which isnt necessary in our cars. A high flow one will do the same thing and its legal.
Do have any more questions/need pics?

i do have a couple more questions. first off, i should've been more specific with the filter question. i've seen you guys write that the 4750 is good because it has a lengthy flange for easy coupling and it has a place to put the IAT right in the filter. i'm basically wondering if anybody knows offhand of another k&n that offers the same features for a lower price. i'd like to do this the best way possible and use a 3" smooth pipe with the IAT in the filter for optimal flow. second, what is the best way to lengthen the wires on the IAT? i read that someone thought splicing may affect signal flow through the wire. and third, what'* the best way to support the CAI once it'* on?

Macho, I had problems fitting my 6 inch filter in there, so that one thing he is talking about would be a pita. Thats what I meant by more engine room in the series 1 compared to 2.

I will check my filter dimensions tomorrow for you, though I dont have the hole for the IAT in the filter, I suppose if you really wanted to you could drill a hole in the end and stick it in there.
As for lengthening the IAT wire length, splicing is a nono because it might screw with the resistance readings. The best way to do it would be to get some thin wire and solder them to make the wires longer.
If the material you use is light enough, the coupler that connects the intake to the TB will support it just fine. Look at Twisters for an example, he was able to make his pipe fit better than mine.

As for lengthening the wires, i just bought a extension from intense for 20$. Make sure the coupler is very loose over the TB. Simple test is to just let the pipe bounce by itself by lifting it up and dropping it. you can see and feel the stress if there is any. i also shaved off the first IAT hole in the pipe, so i could angle it better.

thanks a lot for the help guys. i'm excited to order some parts and get started on this thing. i'm planning on a CAI, 180 t-stat (or would 160 be even better?), remove the MAF screen, and remove cat converter and install rear O2 simulator (intense sells those, too). anything else i should know before i dive head first into this deal?

160 tstats are too cold for our cars, 180 is the best thing to get. It sounds like you have everything covered. What about a free-flowing muffler?
