i was wondering what you all think of these, are they a waist of tome for me to buy right now or not

API Throttle Body Air foil

Throttle Body Bypass Kit

also was wondering what mm i have for a throttle body on a stock 91 Z28 5.7L and what would be a good size for me to go up to, still want to drive it on the road from time to time, thanks in advance.

the air foil is a waste of time/money. never heard of a tb bypass kit and im not sure on your current tb size but a good size to go with would be 52-58mm. something that isnt a waste of time/money for your intake system is the MAT airflow sensor relocator.

 

None of them. Also stay with the 48MM stock thottle body. Save your money for Headers & 3" Catback exhaust system. That will give you the biggest bang for your buck.

 

We are getting an air foil for ours because everybody seems to love them. As for the TB if you go to a 52 or 58mm TB, you will want to port the plenum to get the best flow. We have a 58mm and ported plenum with SLP runners. Probably the best combination.

 

well i have the 3" cat back now and my headers are on there way tonight so i should have them on by next week, so my next step was going to be the throttle body so i guess i'll look into a 58mm, any sug, on a website to check them out??
