Our car got 4 cylinders but control by 1 TB. xan suggest you to mod 4 TBs for each cylinder to boost the performance.
With 4 TBs you need bigger air intake module or CAI to let more air in.
but this will cost you a lot money and your car FC sure sky high. But you gain more HP. Not worth la to mod 4 TB. some more need to change manifold if you wanna mod 4 TBs.
If you just wanna change to bigger TB than the current one. Then better save your money cos the effect is not much. you gain a bit pickup but high FC also.

Thanks for explaining. I'm feeling kinda lazy right now actually.

U know.. weekend.. Friday night..
Here is some explanation that I can share with u, and the costs that may be associated with the whole throttle body idea.
Yes, true that we have 1 stock TB, but what I meant was connecting 4 TBs with a plenum, with each TB controlling each cylinder. NOT 4 TB FOR EACH CYLINDER!! Mau bangkrap ka itu macam..

And yes, with 4 TBs in a line u will need a higher flow of air intake, making our stock intake manifold and air filter redundant. Replacing the whole manifold would cost around RM 600 depending on brand & quality.
FC increment.. Not so. Effect is about the same as modding your exhaust system.
Costs? U can go for a cheapo one, around RM 2xx-3xx plus A PIECE, or branded/high quality ones like Works', which may fetch up to RM7xx-8xx A PIECE. Multiply that by 4, u're looking at around RM 3-4k.
Unless u have that much money to begin with, I would suggest that u go for high-cam instead if u're driving a manual. If u drive an auto, then u can try replacing the stock 1-piece TB with a bigger one, but be warned that the gains may be minimal unless the intake is changed as well (open pod will be sufficient).

Wah y never tell earlier.. I love it.. Somemore Bacardi 151.. and Everclear.. Drank those b4?
Wah wah wah.. Will definitely try!! hehe.. Eh shelby, bring ur Accenture girls aite..
DJ Mixermaster is in da house!
ITB is only good for cars which has either high cams, or Vtec systems like Honda.. No point modifying ur Campro Milo O also.. Without the IAFM and CPS its a useless piece of diecast metal.
Not really lah.. ITB gains are much more obvious in turbo cars where they can gain anywhere from 30-5x HP.. For NA cars.. A max of 10-15HP gain would be realistic..
