    maybe a silly question about a cold air intake but.....

    i searched and saw a ton of cai for an engine with only one throttle body? my engine has 2?
    and a ton of stuff on the drop down tubes i am unfamiliar with. i have always added cai in other cars like audi, isuzu, nissan, toyota. this one has me a bit confused. anybody have this duel inlet with a cai install. thank you

    You realize the car already has a CAI, right?

    Cone filters under the hood are HOT air intakes, which equate to LESS power.

    Re: maybe a silly question about a cold air intake but.....

    no... i assume that is the stock intake. i was wondering because i am not familiar with this layout of tubing and valves leading to the tb. i can wrap the black down tubes in a insulated heatshield to help keep air separate from the engine and radiator. are you saying with this current set up i could just replace the air filter and have the same effect as the whole kit? most times my other cai. are located behind the bumper in front of the wheel well out of the engine bay. it is the way for my maxima and my audi.
    thanks for the info, that is why i ask .

    It is the stock intake, but caddy has always done a good job of making their stock ones as close to cai as possible. The aftermarket ones will be similar. With what they will say is less restrictive flow

    In most cases, if the engine is stock, with relatively low output, the stock intake can flow more air than the engine can use at WOT, at redline.

    If by change the air filter, you mean switching to a K&N (or similar oiled filter), don't bother. You won't gain any performance or fuel mileage, and they flow more dirt, and pack up 3 times as fast.

    Heat wrap won't hurt.

    Are you saying a cai won't really help that much? I have an 04 cts 3.6 like yours and I was considering putting a cai on it. Do you have one on yours?

    I'm saying that in most low performance, unmodded applications, an after market CAI will do nothing.

    Under hood bling and maybe some induction noise? Sure. If that's worth the price to you, go for it. Just make sure it draws air from OUTSIDE the engine compartment.

    I don't have a CTS, I have a Seville STS. No after market intakes available, but I wouldn't buy one anyway. There is a K&N stock replacement filter available, but I'm not spending money for no power or economy gain, and to allow more dirt into the cylinders.

    At last-- a voice of reason on the CAI issue. Let's admit it: it's all about induction sound and maybe a little WOT benefit.

    Re: maybe a silly question about a cold air intake but.....

    yes i agree to a certain extent. i have this from k&n for the stock 2003/3.2l. if in combination with a better exhaust it makes good sense. if i remember right for each 100 lbs of weight reduction is equal to about 10-hp increase etc. or 10-hp increase is equal to 100lb weight loss. i will have to see how the intake can be put outside of the engine bay. thank you for your thoughts. i will let the good folks know what i can come up with.

    i am going to investigate a tube going into the space between the wheel well and fender. i had to do something like that for my maxima. if it is done right it is good as gold. my biggest obstacle is the carb emission hoops in california.
