what do you think of aps tall boy for my tt setup? or any suggestion?

 

they have all shown similar gains.. so it doesnt really matter which way you go. Its just a personal preference of looks. But most people just go with the spacer.

 

Once you are forced inducted the gains found in the intake manifold (plenum) seem to be more obsolete. Plenum mods seem to be more effective when you are made to naturally aspirate your air (NA), and alot less affective when you are forced inducting the air (FI).
