Most of the CAIs (cold air intakes) and SRIs (short ram intakes) are simply a "tube" attached to the MAF housing, with an air filter of some type (usually a cone). They rarely trigger a CEL if installed properly, which includes disconnecting the battery during or after installation, so that the ECU can "learn" the new intake. I had one, a Steeda SRI, on my '05 ST, a Duratec like yours, but 2.3l rather than your 2.0l. It made a bit more intake noise, but was otherwise very similar to the sealed 100K factory box, except it was serviceable. My Steeda is for sale if you are interested. Good luck.
And, welcome to FF!
