2003 Cobra Parts

[Hammer]

Hehe,
Welcome to owning a brand new "selective" car Doug.
Formal kits should be out pretty soon, but for now, the pickings will be slim. (and for the brave.)

As far as an open element setup, you could argue it a couple of ways....
1. An open element setup (Like a K&N Filtercharger) may get warmer air, but there is no bend in the tube nor restriction in the air flow before the MAF.
2. In the CAI's favor you have the cold (or less hot) air from the fenderwell...

As far as dyno #s, I've never seen a palpable difference in horsepower between the 2 types of setups. (Just an opinion from my experience...)

Like I said, I would contact Mike at Dallas Mustang if you have specific questions as they've already played with a few 03 Cobras.
(especially exhaust work...)
