buy a power throttle body ($149) 65 or 68mm. or spend your money on something else that will improve your car more

 

feedback about this throttle body?? the TB stick or not?

 

no, it doesnt stick at all and its really good quality. aebs makes some of the most quality products in the industry and i wouldnt hesitate for a second to put one of their parts on my car. im running the aebs 68mm throttle body

 

68 MM its not too big ?? you run it with the OEM INTAKE?

the gain its in HP or moore torque? at low or high rpm? thank you

 

then get the 65mm. no with an edlebrock intake manifold.
vtec head= get edlebrock intake manifold
non-vtec= get skunk2 intake manifold

both. and both.
