Iv'e been reaserching these individual tb induction kits and everyone says theres is the best. (no suprise there) but im not sure exactly how these things work. If I understand correctly then its like straping 4 TBs right to the cylender head where the plenum used to be. Is that the gist of it? and if so, wouldent that be damaging to run your engine with no filter? thanks guys I feel like I should understand what these things do for me before I decide if I want one.
