I am ordering a throttle body spacer and I do not know if my truck has drive by wire throttle body? 04 silerado with a 5.3

 

STOP!!

Why? TB spacer is only good for drilling and tapping for a nitrous plate, otherwise waste of $$

 

No Bill they make a really cool whistling sound when you huck them at squirrels

 

Really? I was doing a series 77 k&n intake granetelli mass and the throttle body spacer. Should I use this intake of is the volant better? or another brand?

 

i think volant is designed better IMO and im happy with mine..and NO TB spacer

 

why does no one like th tb spacer? no hp gains?

 

NO GAINS!!!

i wouldnt even reccomend the maf, spemd the dollars elsewhere, i hear good stuff about volant!!

 

all they do is whistle.

 

snake oil...

throttle spacers dont work, granatelli mass airflows do not work. while im at it dont buy a hand held programmer, do not descreen your stock mass airflow sensor, do not buy electric superchargers, do not buy gas line magnets, do not buy super gass additive and theres tons more im sure. its all gimics that dont work

 

X2 dont waste your time with those!
