K&n typhoon intake is the least aggressive and has never thrown a code (that i know of) but has been measured to still give us a few horses and it sounds good also. Ive had it for about 2 years and no problems, even got it on ebay for super cheap. just check out the K&n website and look up your car, they have all the numbers and dyno graphs.
Edit: i have the v6 but there is still a typhoon kit for the 2.3 i4. i would guess its just as reliable, just check the website and your model year.
