Yeah right! Cool.

Well thanks for the info.

You learn something new everyday :p

[QUOTE=tuna]siginicantly cleans up the airways in the manifold, you -will- acheive at least a 15hp improvement in peak performance.

the tumblers are basically a secondary throttle assembly hidden inside the manifold.[/QUOTE]

i was just wondering what they are needed for? (as in, why are the cars built with these if they function better without them?)

thanks

they channel the air over the injector to better atomise the fuel.

and they do produce cars without them... ie the sti :)

thats what i was gonna say...

to make wrx goes slower :D

that's what it seems....

-Luke

what would a workshop charge to remove these?

any particular reason it differs between the rex and sti?

is it more expensive to build them without tumblers?

thanx

-Luke

its a fuel effiecency thing.

understood. Thanks!

(no more silly questions from me)
