Any suggestion on these ?

I only had seen so far the ones from Z1.

Open to listen what's the best or who to purchased them from

 

EPS,motordyne,SOHO motorsports

 

ported or larger throttle bodies should be one of the last mods to add. it doesn't add much power if any if you don't already have all the other bolt-on mods.

I have EPS throttle bodies and would recommend doing headers before throttle bodies.

for intakes, you have plenty of choices, for the easy of things, i would push for Z1 since they sell theirs with the race filter option. I went 3" intakes but there are some folks putting down just as much power on 2.5"
