Good question. Any experts out there in this field? cmon there has to be someone of all the members on our forum. lol

in terms of hp gains, there's not much difference between all of the intakes made for the IS:
you could go w/ a joe_z/plp pipe w/ a drop-in filter
shortrams - aem, injen, fujita, K&N, SRT (w/ race ecu)
only true cold air - lms
(note: watch out for the earlier/1st gen intakes - some have thrown cels)

SRT is going to be your best bet in terms of HP gains, however it comes with high price. You could find a new one over on .net for about $300.oo though.

yeah but srt comes with ecu upgrade and doesnt add that much more. i might as well get an aem intake and the ecu separate. plus i intend on going bigger with the computer. i think the cold airs gonna add a little more than the short, i was just looking for some reassurance.

But the SRT has been proven to add the most HP

i was wondering for the is300 which intake brand gives the most horse and torqe.

Apex84

the SRT gives the most HP

SRT w/ R-ecu will be the best bet if you just want to keep it a simple N/A setup. The R-ecu adjust your A/F ratio good enough to make decent power.

However, if you want to fine tune your car, or want to go full out N/A setup, than there are some other possible directions you can take...

1. LMS CAI or KN FIPK w/ Apexi SAFC-II <<<< Probably most popular choice
2. LMS CAI or KN FIPK w/ EMU <<<< Tune other things as well as A/F ratio
3. LMS CAI or KN FIPK w/ Full Standalone of your choice <<< Big Baller Status

PS: other thing to consider is whether or not if you are planning on boosting your car later on. If so, I wouldn't waste money on some of the N/A goodies.

all those n/a parts are usable with boost xcept the knfipk, right?

If I were to get the SRT, how much of a benefit would getting an exhaust be? All these exhausts have a 4.5" outlet which is just too much for me...anybody know of a less flashy, smaller outlet exhaust?

Where can I get it for $300?
