some of the fastest in the 1/4 mile use these ams and buschur fmics, however look at any of the fastest track evo's in the world.... there is a wide variety being used. anywhere from arc, hks, blitz, buschur, ams, ect...

like said before there are many names that go unsaid in many of these threads to keep the product base american made...

i have absolutely no problem in that i just see it fit to put japanese parts on a japanese engineered car... i guess thats just my opinion

 

Are you refering to the HPF FMIC?

 

American final made? Where are the cores to these american made intercoolers made?
