What kind of throttle body should someone get for an 04 Cobra? What size and brand would anyone recommend? Also, this is a dumb question... but what does N/A stand for? Just wondering.

 

N/A stands for Naturally Aspirated. No Supercharger, No turbocharger, no nitrous. It pulls all of the air it needs from the outside air. No forced induction of any kind. The GT's, V6's, 99-01 Cobras, and Mach 1's (kinda) are all N/A. '03 and '04 Cobras are Supercharged from the factory so they are not N/A.
