Cold Air Intake - LOFOCI WAGON - 05-24-2008
Okay, I have an 05 2.0 Duratec and am having a hard time finding an intake! My choices seem to be, Focus Sport or AEM? Either would be fine however, I want the Blue one from AEM. Is there a site that will deliver an AEM inake to Canada? Thanks for the help! :huh:

K&N and steeda are available as well.

Cosworth as well <--Also blue, if that's what your concerned about

from what i hear cosworth doesn't make theirs anymore unless they're talking about the header, i can't rememeber which lol. anyway, they're also very expensive.

I just had the K&N FIPK kit installed on my '05 2.3L today and love it.

The Cosworth CAI (if you can get it) modifies the overall inside diameter of the MAF housing which in turn changes the amount of air flowing into the engine vs. what the MAF "thinks" is going into the engine. The main reason I went with the FocusSport CAI is because it uses the factory MAF housing tube. The Cosworth relies on a baffle to slow down the air so that the volume being seen by the MAF is roughly what it sees when stock.
I had also heard that the inside diameter of the FIPK from K+N was different than the stock housing, but that's not proven by me nor did I do enough research into it at the time.

CAI's from AEM and others also do this... because it gets you some horsepower without tuning the engine.
At part throttle, the engine learns out the differences in the tube diameters so the engine runs alright, but at WOT, you hit airflow numbers that the engine hasn't compensated for, and your mixture leans out a tad, which results in a little extra power up high... that's why CAIs that use their own MAF tubes tend to see more HP gains than those that don't.
If you tune for the new MAF diameter, you'll undo most of that difference. However, in the end, a larger diameter tube will make more air available to the engine (intake diameter matched to throttle body diameter would provide the greatest gains).

will that change in MAF signal cause the car to deto? it will for sure in a WRX but somehow i dont think the focus motors are tuned that aggressively
and you could always keep it stock and remove the silencer for the airbox to make it louder

I went with the AEM Cold Air Intake! I am going to powder coat it the same color as my strut tower brace from focussport! Thanks for your help everyone!
