i like the whole effort mazda put into the tmic having its own air duct built into the hood, all the tmic available fit into the housing. also tmic LOOKS so much better than FMIC its right there for your eyes to glisten upon, instead of the baby rectangle you get to see through the bumper mesh on the FMIC. and even more so, what happens if you get into a small accident? i was in a head on with my MS6 but NONE of the engine components under the hood were damaged at all, it was only cosmetic (and not my fault lol) but if you have a fmic, the slightest accident with destroy a lot of expensive stuff becuase of the tight fit up front. its a pretty big variable, but i like working with the space given to me. also theres a little less turbo lag from a top mount, and the overall look of the car is kept clean. also i think the disi looks pretty ugly without a paintjob, dress up kit, headers, and manifold to go along with it. the only good looking FMIC is the corksport IMO, becuase they use the top mount air duct and turn it into a ram air intake. everything looks really good with that setup.
