intake manifold
#4
#6
Basically it opens up shorter runners at above ~5k rpm and everyone knows that shorter runners at higher rpm gives better hp. As far as the HP gain its mainly prevents the high rpm losses inherent in the lowend torquey stock intake manifold so at 6500 your hp is ~175w/MEVI instead of ~150w/USIM NA of course. Boosted these number could be even more exaggerated.
